CO2 Tank Valve O-Ring Leak Stopper Permanent "ABC" Seal Washer Insert

I had a sloooooow leak that was driving me crazy. Tried multiple gaskets and changes and lost a large tank of co2. This thing seems to work well as no more leaks. Just remember, always lube your O ring.

I had a leak on my kegerator between the tank and regulator and this did the trick to seal it amazingly well. Installed it onto the tank putting some keg lube onto both sides of o-ring, removed the plastic washer from the regulator and I have absolutely zero pressure drop on my high pressure gauge after hours of having the tank turned off. What a life saver, highly recommended!

I used this on my CO2 tank and hand tightened it on the nozzle of the tank. When I attached the CO2 regulator something did not feel right. After taking it apart again I found that the upper part with the O ring that makes the seal had broken off the threaded part rendering the part totally useless. Not worth a penny in my opinion!

Fixes the leaking problem that Co2 regulators have. Just don’t leave it on the bottle when you exchange it!

Great product just remember to lube your Oring

I use these leak stoppers in all my CO2 tanks, but remember that some regulators have them installed already, so I also add a nylon "O"ring also between them.
