Permatex 80631 Thread Sealant with PTFE, 1 oz. , White

My 5-stars is for the product itself.Shipping wise.... half of them were opened in the box during transit. One completely emptied inside the box, another halfway, and the other two were trickling out. I got 8, four were fine, four were not.The price is not bad for these size bottles, so I'll likely order again.... just cross your fingers it makes it to you without too much loss.The caps on these bottles come off with about half a turn, since they're so short, it's a single thread keeping the tops on so if you get a few at a time, they will likely shake around and uncap each other. Hopefully whoever packs the products for shipping, keeps them in a more confined box, there was some decent room for all my bottles to move around in which is likely the cause of my mess.

Used for head studs.

Ptfe thread sealant works great on all applications including head studs through water jackets I even used it on a break line flared union with and it didn’t leak definitely recommend this product

It's from Permattex , of course it's 5 Stars.

i think this is good stuff....permatex quality is tops....but this stuff is quite messy to use, its a sticky thick paste/liquid that doesn't flow and it forms a dry surface film quickly....i did 6 one inch pipe unions and it ended up getting everywhere, especially when trying to wipe off excess.....but there are times when its the best sealant for the situation....the bottle doesn't say what the right solvent is, it's not water as far as i can tell

Need a sealant for my compressor and tried this and it works great. No more air leaks it seals the threads perfectly.

way better than Teflon tape and easier to use

I have been using this product for years, it ha many uses, I used it in the automotive industry, and I use it for all kinds of plumbing, PVC, brass and copper, little advice, clean the jar and seal tightly so it doesn't harden on you
