Vibra-TITE 440 Purple Hydraulic and Pneumatic Anaerobic Thread Sealant, 250ml Bottle

Worked great on my tractor. It sealed the hydraulic connector and it’s held up like I’d hoped it would.

I used this to seal all the fittings on my rotary screw air compressor and all the piping/attachments. This ix EXACTLY what I have been looking for. I have had ZERO leaks and the viscosity is great. Pipe dope is gummy, and tape is just crap. I am here ordering my second bottle I was so pleased with it, and thought I would write a review. Im shocked Vibratite is not a household name, but Loctite is. I would also recommend trying the VC-3 for normal threads you dont want backing out from vibration. I also love that product and it lead me to try this product.

It seems like good stuff but it came with not even half full.

It seals threads used in high pressure hydraulic fittings. Does a fine job.

Did not work, 4500 PSI air fitting and it would not seal the threads

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.

Anaerobic curing means it cures when there is no oxygen. The bottle seems empty but it needs oxygen so it does not harden. Will buy some soon.

Put this on instead of thread tape and the fittings leaked. I switched back to hydraulic thread tape and back to no leaks. Bottle is about 1/3rd full. Its shifty. I wont be buying from Vibra Tite again.

It works. Just remember no oil can be in the joint when you use this sealer. Clean everything , use solvent if necessary.

The sealant that came with my Quickjack car jack wasnt working and it was leaking ATF through half the joints. I decided to try this instead. Pulled everything apart, degreased with brake cleaner, added this and reassembled. No leaks! Make sure to allow for curing time before use.
