I have never worked on hydraulic hose, i do not plan to. I watched your entire video for absolutely no reason and now i have more useless trade knowledge. thank you, i learned all my best skills out the back of a van.

You'd be a great teacher. Where I went to school we had Manufacturing Engineering Tech prep. I had a great teacher. Seriously man if ever you are given the opportunity you should teach your craft. You have a relatable demeanor. You explain things with common sense. Most importantly your humor could captivate the attention of a teenage male audience. Seriously I think the world would be blessed if you were a teacher even part time at a vocational school. Hope you consider it if given the chance. As always rock solid content dude.

Hardly anyone knows the size of the hoses correlating to the #4/#6 etc. I've been working with hydraulics for over 15 years, and you're basically the only other one that I've seen explain it that way.

I've always used a company qualified and insured and it sure paid off when we had a bad hose on a case 580 on the campus in one of the main pedestrian ways. Just a drip but still unacceptable so I went to a great company in Mesa AZ (multi equip dealer, good guys) and they made us one and we installed and it blew out the fitting and leaked 10 gal hyd oil all over. When we took it back a Goodyear rep happened to come in and saw the hose and checked the spu on the hose and it was on a notice of a bad lot and they had not been notified yet so Goodyear bought it all. Saved our asses. Pays to use a pro with the right stuff. Good videos, I enjoy these indepth and sane reviews. Be safe

I drive forklift at the warehouse damn near all day. Your Videos occasionally cover crap that I work with. It's nice to see some it. I Ain't gonna repair that stuff. I've seen how some guys abuse the equipment. You sir are a National Hero

Really good breakdown. I'm in aerospace, but you explained it simpler than the people I learned from long ago.

Thanks for the video. As an machine design engineer, I spec hoses and fittings all the time and now I know how they’re made.

I'm about to graduate from tech school and work for an equipment shop that works on skid steers, telehandlers, tractors and more so this will definitely help out. Nice vid man👌

“Bang bros for mechanics.” That belongs on a tee shirt.

Love the long format! I teach Chem and Engineering to high school kids. I try to make sure they leave the class with "Don't make this stupid mistake and end up dead" knowledge. That stuff is always missing from the textbooks for some reason. Would love to see more from you on that. (I already use some of your life hack safety reviews.)

As far as not unusually cut o rings theres only a durometer difference between o rings of seperate sizes. the higher the pressure the higher durometer needed. Furthermore the o ring needs 10 - 25% of space in the groove it fits into. This space provides room for the seal to expand into when energized. If the ring has no space in the grove then it will be extruded in between the sealing face and the seal will leak. The oring also requires a certain amount of preload, my experience is lower pressure systems need more preload on the oring between sealing faces as they will not have such high pressures to energize the seal. It seems wierd but low pressure systems are often more finicky to seal than high pressure systems.

Thank you as a forklift operator you give insights into how our machines work. Thank you for the information

Only part way into it, and I appreciate the sharing of knowledge. Very nice for up and coming people in the industry. Some random bits that are good to know for the new guys: JIC are all SAE fine thread, so if you have buggered threads you can chase them like a bolt. The "dash size" is how many sixteenth of an inch the hose ID is, so -2 is 1/8" ID, -6 is 3/8" ID, and so on. Parker and some other companies make "seal savers", which are copper cones that go on the flare to prevent galling when you really crank them down. You'll most often run into AN/JIC (ANs are Army/Navy spec JIC fitting, usually made out of aluminum), ORB (O-ring boss), ORFS (O-ring face seal), NPT (which sucks imo since there's always a leakage path, hence the need for thread sealant), BSP (British standard pipe), and BSPT (British standard pipe thread).

The shorts and funny videos you post give me a good laugh, and your long videos are extremely informative. Love this channel

As someone who works with a lot of tractors, hydraulic lines are one of those constants in my life I'm always having to deal with. Sometimes they're a breeze to fix. Just got to unscrew the line, bring it into town, then reattach the replacement. Other times though... They're one of those hard to reach types. Whether it's crawling into a tight space, not having enough room to twist the wrench, or hanging upside down while hot oil dribbles down your arm. It's a job though, and it's gotta get done.

I enjoyed watching you handle your hose. And yes, proper application of lubricant applies to damn near everything in life! I like your style!

I work on race car equipment every day, we use AN fittings and hose which is very similar to JIC (both SAE 37° Flare) I’m glad you know that the dash sizes are the number over sixteenths. not many people know that! I’ve built fuel lines, hydraulic power steering lines, oil lines, brake lines, etc.. using AN and NPT and ORB and even some metric 😬 fittings! Good video!

Personally i prefer the 4% steel 96% recycled shoe plastic shenzhen fittings, but thanks for the tips!!

I used to work for custom crimp or Val power, and machined every component to those crimping machines, started out making the dies then moved onto making all the other components. Watching this video brings back memories of those machines. Parker was our number 1 customer at the time when I was employed there.

I've learned so much on my lunch break at the shop. Always wondered how everyone knew the difference between all the fittings, thanks!

We got a crimping machine a few years ago. Saves quite a bit of money vs having them made and less downtime

From the farm, I’d never heard of these fittings. I’m used to the pioneer fittings. But these are different. Interesting learning such things.

Happy to see you using Parker Hose and Fittings with your Parker Karry Crimp. Excellent choice reliable hydraulic connections.

I usually catch your short videos, but definitely dig the longer ones. Keep on, keeping on brother.

Too cool for grade school. Your skill, education and ability is rare. Great job sharing. Speaking of “whacking with the file” I release the die load slightly and rotate the fitting to a high spot to a die face and crimp again. That removes the burrs and saves me time.

I love the simplicity of your crimping machine, I live in the UK and we tend to used two piece fittings and adjust a dial to the hose size. Its handy if you dont have the correct fitting, you cut the ferrule off the old hose and pull the fitting, pop on a new ferrule and you are in business. Then there is the range of fittings you come up against, BSPP, BSPT, Metric, JIC, ORFS, Boss. Fitting a quick hitch valve tomorrow, the 4 ports have different sizes and types on the old valve and all 1/4 bsp on the new one. Oh joy!

Awesome. I really enjoyed this. I learned a lot about that. I've always had questions and you answered them. Thanks again.

I’m a transport mechanic. We use gates hoses and the PC 707 crimper. Gates products are really well made (Parker makes great stuff too) but gates has an app (e crimp) which gives you a lot of great crimping data. It’s very helpful to learn from. Thanks for the awesome video bro!

Thank you for the video! My old boss taught me how to make hydraulic hoses, but he never went too much into the technical data. I just got my self a cimper for my service truck and I’m glad I found this video, learned a lot

I am installing hydraulic hoses on a exercise pool. This video was great just to understand what I am looking at. Nice to familiarize myself with stuff beyond the manual.

THIS IS YOUR BEST VIDEO YET! Keep em rolling dude. Bravo.

I do Commercial and industrial hvac. I always keep anything spare. It may sit in the van for years but you'll need it the moment you throw it away.

Thanks for that, I work with a large variety of hydraulic fittings to calibrate pressure gauges, the explanation on why we use tape to seal tapered fittings is very helpful. I didn’t notice you mention BSP fittings, perhaps they are less popular in America or maybe I just missed it

You did a great job . The size explanation was spot on . The flat seal fittings are touchy . They go on how many flats to tighten . Really enjoyed the presentation.

Love the long videos, plz make lots more.

I’ve replaced quite a few hydraulic fittings in my day. I learned a few things here and we used the same Parker crimping machine. My current job has no hydraulics. Thanks all the same.

I've noticed my crimp connections have rings around the bottom, either 2 or 4. Sometimes the lines are solid & others dotted. My co-workers & I call them "ought" lines. When we have to make a hose I just duplicate the old hose best as possible including using the same lined crimp coupling. I've always assumed these "ought" lines were for 2 braided or 4 spiral reinforced hoses but can't find any documentation online or on KZfaq to confirm or disprove. Do you have any ideas on this? Great video BTW. Very informative & easy to understand. Thanks.

After I watched your video a hydraulic line blew up on my tractor. Thanks for the info helped out alot

Chill intro, Good content, and an ending that made me laugh, this channel is great

Finally someone who explains the die* difference in a video. So many videos without that explanation. Thank you

This is really helpful! I work as an elevator mechanic Apprentice. We use high pressure oil lines of the time.

Bang bros for mechanics love it haha “well I like to slip it in there and have a feel for that inner lip” lmao cracked me up! Nice work!

Unpretentious, helpful, informative, intelligent and down to earth. Are you sure you are not secretly Australian :D Love your work!

Very well done. Would love to see more long form instructional videos.

I use to watch your funny shorts videos, but i found his i think its very helpful. Thank you.

Here’s to hoping I have all the right stuff and that my manual fitting crimper actually works. This video helped, thanks! Hose got here today, fittings will be here Wednesday. I can’t afford to have a shop make all the hoses I need replaced on my 60’s model Massey Work Bull 204 (front loader and backhoe pretty much all need replaced.)

great video, thanks man! You're a real likable guy too, interesting to listen to. You don't waffle useless stuff just speak sense. Happy to buy you a beer if you end up in NZ.. cheers 👍

Really clear explanation. I learned a thing. Thanks!

I have to deal with hydrologic hoses at work because i'm apprenticing as a tractor mechanic, so i do know some things like how different fittings seal. But things like crimping aren't something we do as there's a specialist for hoses near by, so it's easier for us to just go and order new hoses from there, and we won't need to have the hydrologic stuff clogging up the parts storage. And even if this wouldn't be relevant to me, it's still interesting to see stuff like this being explained.

Thanks for making this its been a mystery to me on how these are made. Thanks !

Good stuff, love the longer videos

GREAT VIDEO!!!!! I JUST PICKED UP A PARCRIMP UNIT WITH ONLY 1 DIE [GREEN] . I UNDERSTOOD THE BASIC IDEA OF THE CRIMP MACHINE BUT NOT THE SIZE OF HOSE AND FITTINGS.. THANKS FOR A EASY TO WATCH VIDEO !!!!

"Bang Bros for mechanics", that's a killer!😂😂😂

Great video! I learned something today, Thanks

I don’t think I’ll ever use this information but it was interesting to learn anyway.

Really good vid, You’ll find most places wont re end hoses because every manufacturer’s hose is designed for specific fittings and matching dies. Its a material and tolerance thing, as others have said, its for a reason, lucky = leak, unlucky = hoses blowing out of fittings and associated disaster.

I love learning stuff in the back of a van. My current job. My technique for making hoses is to go to the nearest hydraulic shop. My last job. I had to make all my own hoses. We used gates hose/fittings/press. To my knowledge as far as making hoses. Gates fittings are used only with gates hoses. Parker are only used with Parker. I heard that the Parker hose machine is way easier than the Gates.

I’m a pretty shit DIY guy and everything I touch usually ends up worse than it started, so I like watching your videos as it gives me hope that I’ll learn one day. Would be great to see more of these type of videos and/or random work stuff. Keep up the good work.

Your a really good teacher my man

Very Informative and comprehensive, thank you very much

I have been a hydraulic technician for four years now and this is so good There's so many fittings JIC BSP ORFS METRIC JIS

I like these long video, very informative and Helpful. Thanks

Bang bros for mechanics😂 shit like that is what tells others that you truly are a real mechanic, love the vid man. I don't mess with hydraulics but at least I'll know more when I go get some lines made soon

We’ve had a hose crimp and all the accessories in the service truck for several years but no one knows how to use it. I finally pulled it out are started looking at the hose fitting chart and crimped my first hose about two months ago. Honestly I was like, what was so fuckin hard about that. I’ve made up maybe 10 hoses now. This video really helps with the finer points. Thank you very much!

Very interesting and very informative, thank you for making the video dude

I work at oriellys and make multiple hoses a day. This was a well made video!

Thanks for the tips! I’m a welder but this is good to know

Feel like you're next long form video should be you showing us how to fix that air compressor.

Thank you for showing us how to do this.

I’m happy to learn this.

in case you or anyone else doesn't already know this: given that ORB and JIC are the same threads without the same seat; "in a pinch", you can always plop the proper size o-ring down onto an MJ to replicate the MOB and be ok.

"I'm becoming bangbros for mechanics" Instantly made me sub lol

Great video man, very informative.

Worth watching just to hear “I’m becoming bang bro’s for mechanics”. Thanks for that! 😂

Thanks for the content man.

Great content for mechanics and Maintenance guys, well done, make more !!!! Show us a cylinder rebuild! Better yet make yourself a parker rep ! You would get more sales then most reps do when they visit plants !! Lol I would love to see a no BS sales rep presentation!

Thanks for this great video

This was awesome info, thanks for that. You taught me a lot. If I ever find a inexpensive hydraulic press I will get one just to have it (Parker is far too rich for my blood). Cheaper than buying a hose. Mainly because I want to replace my hoses on my truck with serious overkill hoses lol

Thx. I love your channel. This was so new to me. Who knew ? I’m a gnu.

@funk fpv I use the same crimper as yours, there are in fact different dies for the crimps. We use a variety of 26 series crimps and 43 series crimps from Parker. They have 2 different part numbers for the dies and they are NOT interchangeable (ask me how I know lol). Everything in your video was great but the line about the dies only being different for the hoses and not the crimp fittings could really fuck somebody over. I can send pics or make a short video and email it to you or something if you want some reference. keep on keepin on

One thing you must always always remember when building a hydraulic hose is the ID must be smaller than the OD or else the hole will be on the outside of the hose and it'll leak like hell

Thank you man for doing this

Thank you. Thank you. Thank you.

I learned a lot here. Planning a project that will involve hydraulics and I feel better equipped to order and assemble parts.

Thanks so much for this video

Love this!!!

What’s up brother. Glad to see another video!

I like JIC cause it'll usually give you that little extra to tighten down if it's leaking. Once ORFS starts leaking, you really can't stop it unless it's just from being lose. I'm biased towards ORFS just because that's the majority of what I deal with at the dealership I work for.

I'm must be getting old cuz this is quite interesting to watch and learn.

Thank you bro.. lifesaver

Great video!

One trick I was always taught in seating the fitting: give a slight twist and if you feel the resistance of the braid, you know that you’re in. I always enjoy your content, and as someone who makes hoses somewhat regularly, I appreciate all of the insight!

Service guys rock

"Bangbros for mechanics" Muahahahaha Love the videos brother, keep'em cuminn :-P

I thought JIC stood for Just In Case!🤣 Good video!

Do more vlogs man love your repair videos 📹

The only hydraulic fittings Ive ever messed with are on airplanes. Its nice to hear about other facets of the hydraulic power.

Just learned something new today...!!!! I've done research on why it's important to use the correct blinker fluid...!!!! Can you explain the "why" using the correct blinker fluid is important...????

Very informative

Humor of the day. Bangbros for mechanics!
