Vibra-TITE VC-3 Threadmate, 30 ml Bottle with Brush Cap Applicator,Red,213

They used this were I used worked at the US Naval Ship Yard as an alternative to Loctite type products or Teflon Pipe Tape. I worked in he Diesel Shop and what had been happening is that when Pipe Tape was used on Screwed in Plugs on the Engines bits of the Pipe Tape sometimes would come off and end up some place in the Engine; in particular the Fuel System and cause grief.They started using this stuff to idiot proof the Job.Also Loctite type Products work but can sometimes be difficult to take apart.you spread it into the Threads and let it dry and it dries to a rubbery coating that seals and keeps stuff from coming loose. Once the Threads are coated you could put the un-used item on the shelf and come back years later and use it. Many Auto Part screwed in Plugs and Sensors come pre-coated with similar stuff.What ever you assemble with it will also dissemble easily later and the claim is you do not need to re-coat (you get a bout 3 uses without recoating). I have never tried that claim. But you can see the usefulness of that if you have a Mountain Bike or Skateboard that you need to take apart and re-assemble on the Road somewhere.The stuff is more expensive then Loctite type Products and not easy to find locally and then only at some exorbitant price.So that while it could entirely replace Loctite type Products I horde the tiny Bottle and use it only for special applications where Loctite is less likely to do a good job.This is a mundane example but I have an Electric Frying Pan that the Screws Vibrate that in use the handle Screws Vibrate out of. The Pan gets too hot for Loctite but the Vibri-tight works.

After reading some reviews and with the recommendation of a couple of g-nsmiths, I decided to try this. I've yet to use it on a fire arm or optics, but I've used it on some outdoor power tools and on a wood chipper/shredder where the manufacturer recommended "blue" thread locker. This seems to work better. There is a delay since you'll have to wait for the product to dry before assembly. Then it somewhat feels like you're using nylon lock nuts when you're threading the nuts on. There's definitely resistance there. So far it seems to hold the nuts and bolts in place. There hasn't been a change in torque values (for the fasteners that have such requirements).

Easy to apply and will definitely keep your firearm screws and such from backing out. Would recommend over locktite as it doesn't dry brittle.

Worked well on my pistol optic and shotgun stock screw. Before Vibratite, I was using the usual loctite blue but that did not stand the vibrations and jolts caused by a 10mm pistol and 12 gauge high brass shotgun loads. So my optic came slightly loose and lost its zero and my semi automatic shotgun had its stock loosen after 100+ shells shot. I then tried out the vibratite on both my firearms and went back to the range at least three times to confirm that it works and is better than loctite blue. It is confirmed. 10mm pistol optic holding zero perfectly now with no evidence that the thread locker is failing. Same with the shotgun, with the stock being firmly set and secure with no evidence of it coming loose. So, vibratite is good for firearm purposes

This stuff is great. It works much better than the blue stuff in my opinion. Leaves a polymer like coating. Easy removal but stays out. It can also be reused unlike the loctite.

I have used every kind of thread locker over the past 30 years, as a master race engine builder, machinist, and gunsmith. For many purposes I would use this over anything else without question! Not as messy as the other top brands, it can put it on fasteners and let it sit and install later, it can be applied to fasteners that will be taken out and reinstalled multiple times and still work great!

It's the real deal. This is great threadlocker and I use it on all my pew pews. The size of this tube will last me years, easily.

Works great
