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. -- Tom Sargent ________________________________ Message 2 _____________________________________ Time: 08:59:49 PM PST US From: Dave Saylor Subject: Re: RV-List: leaking nylo -seal fittings 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. --Dave On Sun, Jun 22, 2014 at 8:29 PM, Thomas Sargent wrote: > I have a pretty big leak in my static air system.
