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

Works great - just as advertised.

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.

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.

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

Worked well for several 1/4in NPT hydraulic connections.

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

They show a big bottle but is only about a quarter full

works great.
