I'm more confused now than I was before. I didn't think that would be possible as I was pretty confused before.

Jamie, please help me find the pipe thread gage on your website

Fantastic video.

Great video. Thanks I have some questions. 1. What kind of thread is on the side of the check valve? The little female threaded hole? 2. I have a Quincy QT-54 air compressor. The unloader valve had a 1/4” OD copper tube attached to it. It’s a male thread that looks like a 1/8” MPT but it’s not. I need to convert this to a 1/4” NPT somehow. So I need a female adapter that screws onto that male thread on the unloader valve and has a 1/4” NPT on the other. Can you help me to choose the right part? 3. My 1/2” OD copper tube from the compressor connects to a brass fitting on the tank. This is where the check valve is. The brass cross has two small female holes on either side. One is for a PRV and the other is for an elbow that hooks to the 1/4” OD unloader tube. I want to replace this whole thing with a new check valve with a 3/4” MPT on top, a 1/8” FPT on the side (for the PRV), and whatever male thread there is on the tank. Can you help me on this too? Sorry for all the questions, but all these different threads are driving me nuts. Thanks, Paul

I bought a can of R600A. It has a little smaller self healing top than the usual refrigerant top. When can I buy a Schrader valve that fits this top, OD 0.414" ID 0.392"?

Good stuff bud Now we just need to know what fits inside of the EGR tube nut on an F-150 Lightning (Yeah right)

Holy mackerel ! Ya gotta be Euclid to get the right size.

Actually, a better bit of info would be, what size tap and dye would i use to clean up bad threads on a flare fitting? I.e. 1/4”???

Too bad you didn’t actually measure the last fitting so I could see what part of it to measure.

Do you have a link for the ruler that you sell? I can't find it on your site.

OK but you didn't explain WHY pipe thread diameter is 1/4" larger than the measured thread diameter. That makes no sense, there has to be some logical reason why they are sized that way

JIC is more in depth? Oh dear God...

LOL

Why don't US start marking thread size by actual thread size!? You are confusing all the world. Thread size is 3/8 (sorry we have not mentioned compression), good luck finding adapters. We have adapter 9/16-19W! Nope you need 9/16-24. Aaaaa.... And don't get me started on imperial measurements.

what the fuck is this??? It drives me nuts!

Terrible video. The narrator holds the measuring device facing himself and measures the fitting that is down in his fist, nothingwe need to see is visible. Further, we cannot SEE what he is measuring, the OD of the fitting, the ID of the interior of the fitting or the ID of the inner diameter of the threads themselves.

that ruler is politically incorrect!!!

More lost than before
