This product has excellent solvent resistance and withstands temperatures to 300 degree F. Typical applications are hydraulic and pneumatic fittings, servomechanisms and fine filtration systems. Ensure parts are clean, dry and free from oil and grease before use. Product is normally hand applied from the bottle directly onto threaded parts. Fixture Speed with Activator is

This stuff did the trick. I tapped my steering box in my Jeep to run Hydro assist steering. Could not get the lower fitting to seal. Tried gasoila, tried teflon, tried a combo of both. Ordered this stuff after reading other reviews. Let it set up over night. No more leak. It works!

I made custom power steering lines for a steering rack that wouldn't stop leaking. Even after correctly installing the application specific seal rings. A couple drops of this stuff on the threads tightened everything up and let it sit overnight and when I filled the system not a single leak. Great stuff

I used this to seal air fittings on a paint pressure tank that was leaking. It only goes to 3 atm, but all the teflon tapes and plumber putties I tried did not fix the problem. I assume this is the loose tolerances in the manufacture of either the tank or the fitting. Anyway, I used this sparingly and let it set up overnight just to be sure and it has not leaked since. Also, I hand tightened the fitting and then gave 1/2 turn with a wrench, but I know from the torque gauge that I would need to apply a LOT of force to get it unsealed - a good thing.One word of caution - the warnings on the instructions about breathing in fumes, touching it, etc., are downright scary. Not sure if all brands have this, but WOW. I used gloves, goggles and a respirator just to be sure.

Sealing threads in a high pressure system (>600psi). Did the job and parts could be disassembled fairly easy after heating

No Leaks on my DIY log splitter NPT hydraulic fittings. Works as it should. Make sure the fittings threads are absolutely clean, I used brake cleaner, and sprayed the threads and dried the threads off with a terry towel to clean the grooves really well. let them air dry for a minute or 2 then proceeded to use these before assembly. The log splitter sees 2500psi regularly. The bottle is supposed to have a good amount of air in it so that it doesn't harden in the bottle. It's an anaerobic sealant meaning that it cures when there is no air, that's the reason for having plenty of air in the bottle.

Have not used it yet, so no comments on its functionality. The 50ml bottle is only 1/3 or even 1/4 full. The bottle looks intact with no signs of leaked fluid from it. Feel like I was fooled by vibra-tite so no more business with them. I suggest you stay away as well.---------------I would like to take my words back. Here is the direct quote from vibra-tite: "Anaerobic products such as threadlockers and retaining compounds cure in the absence of air. It is necessary to have a sufficient volume of air within the container to prevent the product from hardening." This is why the product bottle feels empty.
