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

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.

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

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

I dont have any issues with the product itself. I would have given it 5 stars. My issue is that I received it without the cap to seal it after using it. Now that I have cut the tip to apply to the connections the rest will dry and become unusable for future use.

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.

This is a great thread sealant for air compressor fitting. But downside is when I got the bottle only 1/4 of it was full. Not sure why that is.

Used it on my Victor dual gauge. For my argon tank. Stopped the leak the first time I applied the Vibra-TITE. Great product

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.

Works great - just as advertised.

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.
