Is any kind of thread sealer or other compound called for on the (plastic) NTP threads of the pitot/static connections on instruments? I'm thinking these should just be dry but would like confirmation.
I've always installed them dry Scott, but I can't cite any documentation that says that. Never had any leaks I coudln't solve with a little more tightening...
The plastic fittings (the pipe thread part) should be dry and only slightly more than hand tight. I think the tube and nut end may bottom out on most types. Any thoughts on that out there?
