Cy,

Just looked up Loctite PST and it says "Not recommended for use on
plastic piping". For example I have a plastic fuel level sensor going
into aluminum
tank hole piece embeded in epoxy. It seems that the "TFE Pipe Thread
Sealant
w/Teflon" fits the bill better on that one.

NEVER EVER use Teflon tape. regular Pipe dope with Teflon powder works well
but the very best is Loctite PST.
