As advertised and as expected from this good company - material was thin enough to get into the threads but not runny or fluid like to make a mess

Stuff worked great. Timely delivery. BUT, the tube was less than 1/3 full. Not enough in it to get the nozzle to work properly! WTF?

The end of the tube was not manufactured correctly, so all of the thread sealant leaked out into the packaging.

Q: Is this acceptable to use on a NPT fuel drain valve?

We always recommend checking with your A&P to be sure. This product should be fine for use with fuel but typically fuel drains dont require a sealant.

Q: is it possible to use this sealant to seal the AN fitting in the Christen system?

We recommend you verify with Christen to see what they recommend. We do not have an application chart for this material by aircraft.
