This stuff is great for any threads that are applied to oil connections ...
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.

An excellent product from a reputable brand.
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.

This Stuff Works!!!
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.
