Thread: How do you measure NPT fittings???

Tweet

When you get to the brakes, you will have different fittings altogether to deal with. The back fittings will probably be 3/8" tubing 45 degree flare fitting, and the front probably 1/4" tubing 45 degree flare fittings. I say this based on the cars I have worked on personally, not having checked to see what car you have. IMO if you are replacing the brake lines, the easiest way ( by far ) is to purchase pre-bent lines. Second easiest is to get a good quality hydraulic flare tool, and use regular steel lines and stainless steel fittings. I used PolyArmour steel line. It has a corrosion resistant coating and makes perfect and painless flares.

Thank You!!! ... ok Denny so no washer cuz they don't bottom out. Ah, there's an in/out on the lines? Thank you! I wasn't paying any attention when I took the lines off! ok Ted, I easily threaded both pictured fittings into the transmission so the threads are the same....
Oh, by the way, what I'm doing here is replacing the fittings & lines that hook the trans cooler to the transmission. It was hooked up with a combination of rubber hoses, metal lines & 6 {yes SIX} hose clamps where the rubber hose was conected to the metal lines on one end. It looked liked it leaked & they just keep adding hose clamps to stop the leaking! {ah, but it STILL leaked ..... anyway, I had some -8 an fuel line left over so I just figured I'd use it for the trans cooler lines. Thanks again! Bill
