Does exposed thread sealer ever cure, does the inside sealer cure? ?
Good Morning,
I used permatex thread sealer and the small amount surrounding the sensor on the outside is still uncured (72 hours), semi liquid is this normal? I used the small red tube mnfctr #59214 designated for ""NOTE: Permatex Thread Sealant seals threaded metal fittings on hydraulic, pneumatic, fuel, and cooling systems.""

I had to adjust this question because I did not ask it correctly. Once again getting old sucks, My question is does the inside cure while the outside stays liquid? I was expecting it to harden and am just making sure the threads are sealed. Does the outside sealant reflect the state of the inside sealant ?

Thread locker and a lot of sealant is anaerobic. So on a close fitting mostly air free space it will cure. Puddles do eventually cure but it takes a long while. Unless the bottle was quite old I wouldn't worry about it and assume it is hardened/set in the hole.
If you want to test it put a little on a nut and bolt and snug it down. Come check it in a couple hours and it should be somewhat set...

It was just looking at the extra left outside the threads as you screw it in and it piles up a little at the surface, I kept thinking it wasn't curing. So your saying if it is not inside, soft is what you get, but inside is cured.
Bottle was new.

Mostly. I'm unsure if that particular sealant cures hard or just sets per say, but on the threads it should set at the described interval.

Should be a softer set. not hard. Its designed to seal and allow easy disassembly in the future. If you ever used the hard setting black Permatex you'll appreciate the difference. Should have called that stuff Permanantex!

My bad, I somehow superimposed Red Loctite in my mind!!! You are correct, the white Permatex thread sealant never really gets HARD, even the baked on stuff remains somewhat pliable....and Yes, the black Permatex Aviation Form-A-Gaskset sets HARD and is a b!tch to remove off of anything, good stuff though!! My apologies to the OP, I reread the the original post just now and I don't know why in the hell my mind went to Loctite!👍

Are you referring to #2 or something else? I ask only because I use #2 quite often in places where the regular white stuff doesn't get hard enough but I never found it to get hard or be permanent.

Not #2, I'm referring to #1. That stuff sets up hard like a glue. I only ever used it on stuff that I never planned to take apart. We used it on pipe fittings and years later the fittings would be stuck so tight we've crushed the pipes trying to remove it.
