Permatex 59235 High Temperature Thread Sealant, 50 ml Tube , White

I used this on oil plugs for oil pans, transfer cases, differentials and a few other things. No issues or leaks so far. Easy to apply, reposition and seals well.

Worked well for John Deere oil filter conversion. Also worked well on some gas lines I was doing. Nice and easy to apply with the special tube tip

In my Q.C. lab days, I had a partner who would periodically measure, with a precision optical comparator, tooling for machining threads. He had gauge wires to check the pitch, and go-no go gauges for quick checks. I really wish they used the same exacting standards routinely in Asian manufacturing. I have had more sloppy parts, with off-spec. threads since the East dominated the manufacturing of many commodity fittings. I actually got parts with an apology note enclosed, that said, to use lots of PTFE tape to make a good seal. I ran out of S.W.A.K. anaerobic sealant, which was my usual salvation for loose threads. A new supply of that is very pricey. PTFE tape failed, Hardware store pipe sealant failed. So I tried this. It is a lot like S.W.A.K. sealant. I let it setup for a full four hours. I re-pressurized the system, and thankfully, no leaks. I like the way it goes on as a thick fluid.

Used this on a Nissan Armada rear differential. Worked great. No leaks.

Nice and hefty when spreading around, better value than small tube

Needed high heat sealant, this fit the bill. Can go wrong with permatex!

I used this to seal an old gas line we capped. Worked great. No leaks.

Great product!
