LOCTITE PST 592 Thread Sealant for Automotive: Low-Pressure, High-Viscosity, Anaerobic, Prevents Galling | Opaque, Off-White, 50 ml Tube (PN: 483630)

Stuff works great and exactly as advertised. Used on differential for 2021 jeep wrangler.

I have used this sealant for years!! It seals under many adverse situations with loose and worn threads.Eases threading of fittings and has a long set-up time. I have used this sealant in Many different applications!!!I have used it for many types of high pressure gases up to 250 psi. I have used it on water and air. I have used it with black iron , cast iron, Brass,PVC, CPVC and stainless (all grades). It seals very well and eventually sets up semi hard. It can be dis-assembled, but it is a little stiffer than regular teflon, teflon tape, pipe dope etc.Easier than sealant used for steam applications. I have not used this with steam!! Works fine on fittings for water heaters!!. Coat all around the threads evenly and wipe off any excess on the ends or inside the pipe or fittings.

This is an excellent product from a reputable brand. Use a little just to stop thread galling and maintain a tight seal like it was from the factory. You only need a little so use it sparingly.

Much better than pipe dope or Teflon tape. No leaks. Sealed my oil pressure gauge threads really well.

Great product use it all the time.

This stuff is great for any threads that are applied to oil connections on a motorcycle. Highly recommended. Goes on easily around the threads. It can be a tight fit if applied to the start of a thread application so it's recommended to have this applied towards the end. I used this for the installation of a Jagg Oil Cooler and it worked as it should. The instructions of the Jag Oil Cooler include the use of this thread sealant. No leaks and no complaints. I also recently applied to the end of the oil drain plug after an oil change to ensure there would be no leaks and it worked great. Of course the oil drain plug o-ring was still there so this was applied to the threads just before the o-ring. The o-ring has a tad bit of new oil put on it.

Used for flywheel bolts that enter into crankcase. Stopped the leak that looked like a rear main leak

Used properly and for the correct application, this stuff is awesome!Works perfectly without activator for brass fittings and other "active" surfaces such as iron, copper, bronze, and soft steel.*Requires* activator for "inactive" surfaces such as stainless steel, aluminum, magnesium, zinc, titanium and others.Definitely worth heading over to Loctite's website and reading the "Do It Right" PDF for automotive applications. Tons of great info on how to achieve the best results with a variety of Loctite products as well as product selection guidance among the various formulas.
