race spec fittings leaking oil?


Recommended Posts

The thing with Jic fittings is that you should do them hand tight then one dlat thereafter and no more. Going beyond that and you begin to stretch the threads. Ideally it would be to chanfe for fittings but you could use a bit of thread tape on them. Its not the best solution but it should work.

If you do it that way dont put tape on the cone part of the fitting.

I would try changin your hose ends though dude.

Yeah Army-Navy fittings (AN) should not leak. Something is wrong. lol

The hose ends onto the adaptors (number 2 in photo 1) do not need to be very tight and they are easy to damage. Even anodised Aluminium to Aluminium threads and cones/seats will benefit from lubricating to prevent galling.

If the hose/end is leaking from...

...number 1 in photo 1 the hose and end is not assembled properly.

...number 2 in photo 1 the adaptor cone or the hose end cone seat is damaged. You can get soft aluminium Conical Seals that kinda repair the cone/seat. See photo 2.

...number 3 in photo 1 there should be PTFE tape or a Dowty type seal washer. See photo 3.
