    The best co2 seal you can find.

    Posted by Frank J. Douglas on 31st May 2023

    We use lots of co2 gaskets in our fishroom and GLA has the best there is. We used the paper gaskets that were terrible and always leaked. We used the softy type and they just dont last more than once. Now, these jokers here you can use these at least twice. They say they are made of nylon but this stuff is perfect whatever it is. It crushes perfectly with many of our cylinders with aging valves that are quite beat up on the valve itself so these things fill every scratch and defect within the brass interface of the cylinder valve. Now having used these seals for a year now I came today to buy 50 more so we have a decent supply for the next couple years.

    This is the best co2 seal available.

    I echo what many say in regard to these seals. Really nice crush to them so you get a perfect seal every time. All nylon seals are one time use so dont be dumb, get several.

    This is the best co2 seal you’ll find anywhere.

    Posted by Harold Johnston on 7th Jul 2022

    I’ve been using co2 for over 40 years both for my reef,planted and my home brewery. Needless to say I use co2 seals a lot. I’ve used everything, including the brass seals. This seal is some kind of weird material that’s of the right consistency for longevity and excellent crushability. It seals every time and I even use them 2-3x. I don’t recommend doing this but like I mentioned I go through a ton of seals so I bought 100 seals to last me a couple years.

    Best co2 seal available

    I go through a lot of co2 and have used all the gaskets including the permaseal. This particular gasket is of the perfect consistency and forms a 100% leak free seal every time.

    By and far the best co2 seal available.

    Posted by Scott Ramsey on 9th Sep 2021

    This is a must have by the bag full. You need one every refill and these are 100x easier to use than the stock version supplied with the GLA regulator. The stock units are fantastic, but super soft. This made is harder to dial in the regulator position. By using this seal it resolved that issue 100%. Love these GLA seals.

    Love this product

    I found that the hard seals that come with the canister (i do the swap-out thing at my local shop) does-not work and tightening-down on these makes a nice seal. Buy 2 :-)
