Works as intented
I've always went with the Permanent seals for my co2 tanks. I recently exchanged tanks with my local gas supply company, get home and come to find out the output didn't have the threading inside for the seal to screw in. Knowing the company probably would exchange a full tank or refund I started looking at other options for a seal. After some research it seems alot of people go with these nylon seals and are happy with them and at a $1 a pop I gave it a shot. I wasn't expecting them to be so hard to the touch but tried it anyways. Going good so far with no gas leaks. For the 7th of the cost as a permaseal and works just as good, ill probably be going with these from now on. Thanks, GLA!

The best co2 seal you can find.
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.

GLA Co2 seals are the very best.
Been using GLA seals for years. Perfect seal every refill zero leaks.

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