| Subject: | leaking nylo -seal fittings |
I have a pretty big leak in my static air system. I used nylo-seal
fittings throughout. I never know how tight to make them. How do you
know when to stop tightening? I just use my fingers. The leaking fitting is
a T screwed into my altimeter. I've tested all the components and when I
added the T, I added a leak.
Is there any point in putting teflon tape on the threads to improve the
seal? How about something like a little silicone sealant around base of
the fitting after it's screwed in?
Or do I just keep tightening the thing until it seals?
Thanks for any wisdom/experience on this subject.

Teflon tape on pipe threads (ie, into the back of instruments) will help a
lot. It won't help at all on the B-nuts. The threads that accept a B-nut
are different from the NPTs that go into instruments.
If you didn't use the little plastic inserts that go in the end of the
tubes, that makes a huge difference.
I like using a crow's foot to tighten nylon B-nuts. It's handy in cramped
quarters and keeps me from over doing the torque.
