4 oz bottle goes a long way!
I absolutely love this stuff. Iโve used this Permatex PTFE thread sealant on two complete vehicle engine builds, and Iโm only about halfway through the bottle, which says a lot about both coverage and value. A little goes a long way, and it applies smoothly without making a mess. I used it on cylinder head studs, intake fittings, transmission line fittings, oil cooler fittings, and several other threaded connections exposed to oil, coolant, and transmission fluid. In every case, it sealed exactly as intendedโno seepage, no weeping, and no loosening after heat cycles. What I like most is that it seals while still allowing proper torque, unlike some sealants that either over-lubricate or harden too much. Itโs held up against coolant, engine oil, and ATF with zero issues. Threads stayed clean, fittings went in smoothly, and nothing backed out during assembly or operation. This has become my go-to thread sealant for engine and drivetrain work. Reliable, efficient, and long-lastingโone bottle easily handles multiple builds. I wouldnโt hesitate to use it again on future projects.

Makes the job easier
What can I say....Permatex is a leader in thread sealant. Works great and used on John Deere mower oil filter change over install. Always a little messy but you get confidence in the finished job.

Great all around thread sealant.
Works great on bolts subjected to petroleum. Oil bolts, intake bolts, and any bolts that needs thread tape.

Great sealant!
The best thread sealant I have ever used. I've used it in every heavy diesel shop that I have worked in. When it fully dries its fully sealed. A little goes a long way and it lasts for quite awhile.

Nice but a little thick
It's nice and works very well, but it's a little thick and because of that not always easy to apply.
