John, thanks for the feedback and your kind words.

Thanks for the positive feedback John, So where was the toolroom you worked in, on the surface, down the pit or underground?

Glad it helped

Glad to hear that!

Thank you so much!

Our pleasure John, thanks you for the kind words.

Glad it helped. For what project did you need the help?

You are welcome!

Glad it was helpful! Vinoy

Thankyou, Glad it was helpful!

Hello Joe thanks for the Hi! I am not sure If I sent you a reply last week inviting you to do a collaboration on a Hydraulic Video of your choice did you get that invite? Cheers Minos.

@@Hydraulic.Online sorry for the delay. I just seen this. Yes I'd love to do a collaboration. I love discussing all things hydraulic. I think it would be really fun and interesting to have a discussion of all things hydraulic. Thank you for your response. Just let me know when!

Thanks for your comments Trimaine, how did it help you and what were you trying to understand?

I do not think it matters as far as the actual connection is concerned. Lubricant is recommended for most Airconditioning fittings as it alows for better seating. From my experience appling clean lubricant on the threads and seats will give you better seating with the added benefit of protecting the threads from corrosion in agressive wet or marine environments and also in long term applications. Lubricant on the treads in high vibration applications may be a issue and cause some thread types to loosen. for example in hammer rock breaker applications BSP and code 61 or 62 Flange fittings seem to hold on better than JIC fittings.

You will need the original hose and the ends to be able to identify what type of hose, how long to make it and what type of hose fittings to to use. Without a sample hose and fittings, it will be very difficult to know what to make. If you know the machine type and the function you could take an educated guess based on past experience .... but then again who wants to guess fittings and hose length. You may be better off trying to contact the manufacturer as they should have all those items documented, but it does not mean that they will tell you.

Hi Mullet Joe! Thanks for the comments and the big Hi ! When you are ready to do the "KZfaq Thing", drop me a line and we can do a AU and US collaboration together. You pick the topic. ps Midnight in Montgomery story was pretty funny. Cheers Minos .🤓

Fanzidel You are right they are a Metric thread. And probably a Japanese Isuzu and or Hino proprietary thread. If it is a hose that has failed we carefully cut the old shells of and remove the old hose then "silver solder" part of the original fitting with the metric thread onto a standard hydraulic adaptor or hose tail. On Steel Tubing, companies like "Stauff" have a range of metric compression fittings that adapt to JIC, or BSP threads and also to other metric tubing.

Hello Heinz JIC and its complimentary UNO port thread is good in most applications. If however the application involves vibration or high pressure pulses then BSP seems to hold on better for longer. Metric is also another good option but with its many sizes as well as two pressure (or Light and Heavy duty) options it can get overly complicated.

@@Hydraulic.Online Thanks a lot for the quick response. Very helpful to me.

Try Searching for Plumbing or Pipe Line Suppliers. Also Some Manufactures use a bolt on flanges with BSP treads for the Suction Side of the Pump. Sorry I do not have a way to send you any pictures.

Yok Yok there is no real reason why threads in a hydraulic system are not standardised. Generally it is the Cylinder, Valve, Motor and Pump manufacturers that decide what threads to use in the products they make. During WW II the American Army and Navy did just that and created the AN - JIC / UNO Standard thread connection system. The AN - JIC/UNO system is still widely used in Australia and America. BSP is a British Thread and as the British did colonise many places around the word they took their thread standard with them as well . But as Global sourcing of Products Grow variations of threads will continue to grow as will the range of "Adaptors" available to connect different parts together.

BSP is a type of thread, it means "British Standard Pipe"

You might want to check on the angle of the hose comming out of the fitting, it might be getting over bent or squashed when at certain angles or it could be excessive heat build up from too much of a restriction from high oil flow through too small a hose. Or it could be just an old hose or the wrong type of hose. You might also want to check on the fittings you are using if the shell (ferrule) is longer than the tail this coulbe be causing internal damage when crimping.

Sorry I do not understand your message.

Hi Ping not really sure about what type of connections a Sany might use if they also sell them in the USA they may have JIC fittings, alternatively they might have a derivative of the ORFS fittings (flat sealing faces with an O ring but with a metric thread) and actually called a Chinese flat face. Or they may have European metric fittings.

Hi sorry we missed your comment, how is it all going, and where in the world are you?

Where are you Larry ? are you in Australia or still in the Philippines?

Thanks for your comments Janki are you working in the hydraulics industry?

Sorry are you asking can you use male of female fittings?, the answer is It does not really matter it is your choise, but generally female on Hose and male on pump or valve or cylinder or motor.

Do you want to ask which side of the hose fitting to connect the hose?
