I found this article from Borgelt Instruments useful.

For me, I had a leak in a tiny little calibration tube used with a Scheumann compensator. The tubing literally disintegrated when I touched it. It was rarely checked because the Scheumann is installed behind the gear with an inspection panel access.

The article pointed me to Permatex Aviation Form-A-Gasket No.3 Non Hardening sealing compound which was especially useful for the Scheumann tube replacement since the tubing I had to use wasn't the ideal fit.

Also, found a leak in a vario capacity flask...

And watch out for the all-in-one tubing connectors (or whatever they're called), the little o-ring in those tend to deteriorate. These are identified by multiple tubes leading into a threaded cylinder shaped connector. T-connectors are preferred over these...

If one is getting a new / used glider and wants to check out the Static / Pitot / TE systems on the ground, what is a recommended procedure?
