so i used loctite 545 thread sealant and i still have a few leaks here and there… i was wondering if anyone’s used this stuff and how did they coat the fittings with it.
thx in advance!
Being that fittings are tapered thread. I dope up the threads towards the top of the fitting. So that when it seats the threads would be sealed.
Good Luck.
when i used it i put it on the majority of the threads , especially the 1/2" ones seeying as those always seemed a lot courser thread and took more to seal… When tightening i would keep a rag there and catch / wipe any drips / excess… I probably was a bit wasteful with it but any on the fittings i used it on dont leak! There are still 2 fittings i havent applied it to yet and thats just because of where there located / tough to get to and those are my leakers… Only loose 15 psi a night tho and thats with the temp going down to single digits which finds any leaks u got!
ok, i was doing strips of it longways on the threads. i dunno why i thought that’d be better. i think ill do the ‘around the thread’ way and be more wasteful with it heh.
gonna be a b**** to fix it…
A heavy drop or two on the bottom 2-4 threads ought to be all you need. As you load the fitting (by hand), you’ll see that the sealant fills in all spaces as its tightened. Hand torque and leave the fitting alone. If you so much as tighten or loosen it at all afterwards - you may develop a leak. By far, this is the best stuff I’ve used, period.
Ive actually adjusted one of my fittings a day after i put it in and thought it might leak but it didnt… it is good stuff!
yea i heard this stuff was the best thats why i got it. i blew it on one of them tho wahhh
is it okay to overdo it tho? i just wanna make sure on the next one
There’s no reason to, unless you want to waste product. Just enough will not require you to clean up your mess. If you do it right, you add it, tighten the fitting and walk away from it. Can make a setup look a whole lot cleaner as well since there’s only a tiny bead of 545 left in the gap, not a bunch of nasty thread tape hanging out of the fitting.
It does not hurt if you overdue it if thats what you are asking … I was wasteful with mine… but the threads i applied it to arent leaking 
When you say bottom, you mean the part that is screwing into the hole first?
All the fittings into an air tank should be tightened by hand only??
yes
and
yes, but with a wrench…not just your hands
The ‘hand torque’ comment threw me for a loop too…
