best thread sealant
for Mrod fill valve?
Stay away from the stuff at box stores labeled "Rector Seal"!
I wanted blue pipe dope (teflon) and get some NASTY (guessing) castor oil based non-drying.
Did I mention nasty?
I frequently use teflon tape on the male, and then pipe dope over it and inside the female fit.
This seems to let the tape stick to the male, instead of balling up against the female's face.
Hate leaks..... hate is s strong word, that's why I used it.
There you have it, the world according to John.
