2 Set of 6 - Learn to Brew Nylon Washers for Co2 Regulators

I believe at one point an alternative washer may have been sent out, but the correct washers were sent to me in April 2019. They have the ridge which fits nicely between the CGA 320 CO2 tank and my regulator for a leak free seal. And if you get the wrong ones by chance, send them back for free... I took a chance despite the neg reviews and was happy I did!

What kind of crap is this. I got something completely different than what’s pictured. These washers are white and thin and won’t create a good seal on co2 tank. DO NOT BUY! I got the order today and amazon says I can’t return them

Like me you likely came across this item and thought, "Cool! Twice the gaskets for half the price!" Then you read the reviews and think, "Nah, it must be some mistake that won't happen to me!" You may based your purchase upon those little pictures which show exactly what you need. After that you'll wait five days only to receive a crumpled beige envelope with six very small disappointments. The gaskets pictured are not what I received, but at least I know better than to try to use them and lose a tank of gas.

Perfect for soda stream. I had lost my only small washer that came with my CO2 doctor contraption and this worked out great. Plus, now I have several as s back up.

This plastic / nylon gasket is the perfect and recommendable item to connect CO2 beer regulator to cylinder easily with no leaks. But must be installed correctly. Came in a pack of 6 units (mine came in red). Before installation, follow obviously, all security procedures (you're dealing with dangerous and under pressure materials), and make sure all valves and regulator are closed. Check the shape of this gasket and face the right side against cylinder connection. After that, use the wrench, but do not over tight regulator nut against cylinder connection. Open cylinder valve slowly and be sure there's no leaks at all. Then, one by one, depending on your setup, open other valves and regulator. Check for leaks. You can use a solution of soap and water. Spray around connections and check for bubbles. Or try to put all assembly under water and wait for possible bubbles, that means a leakage. For security reasons check for leaks in a regular basis. When replacing CO2 cylinder, discard used gasket. Install a new one.If you're not sure or familiarized with this procedures, take your regulator assembly and cylinder to a welding shop. They'll do it for you.After that, drink beer (responsibly) and be happy!

The washers I received were not notched like the ones in the picture so I am still losing some CO2 through my cylinder. Not impressed with the flat piece of plastic I received in the mail. The notch (or lip) is supposed to be specifically designed to fit very tightly with a CO2 tank and regulator, this IS NOT what I received in the mail. Quite disappointed!

I use CO2 on my fish tank as it's extremely heavily planted (literally wall to wall plants), and I run high lights and fertilizers on it as well. Anyway, you need something to create the proper seal between the regulator and the tank, and these have been extremely consistent so far. Works well, would purchase again.

I read the reviews the old reviews from 2015 said they shipped them the wrong ones (not even close to the picture) The 2017 review said they got washers just like the picture. Soooo Stupid me I ordered them believing that the company had probably made a mistake in 2015, well guess what I got 6 black rubber washers that have no ridge and are too large to fit in the regulator connection. instead of the white hard nylon washers that are pictured. Its only 6 bucks but a week out of my life.
