loctite 55 as thread sealant

Discuss loctite 55 as thread sealant in the Plumbing Jobs | The Job-board area at PlumbersForums.net

If the thread is super smooth (well machined) I take an old screwdriver and drag it vertically down the thread to create a key for the loctite to grab to. In addition I apply from the start of the thread (ie the first thread to enter the fitting) towards the top, then back down to the start. This way the loctite is pretty sure to be dragged into the thread rather than pushed out when tightened. Love the stuff…don’t get me started on CT1
 
Loctite 55 is very good on rad tails, but I often do it with hemp and paste.

PTFE I keep for threads I don't want to seize up, and for wrapping 3/4" olives to allow connection to 1/2" alkathene. Wouldn't use PTFE to attempt to seal a thread out of choice.
