Premium Nylon CO2 Regulator Washers, Self Centering, Fits All CGA-320 Fittings (12) - Perfect Seal, Perfect Fit, Every Time!

Using these to connect my CO2 tank to regulator for my kegerator. Hooked up my tank almost 9 months ago in my home and have had no leakage. Works on typical CO2 tanks.

Appear to be reasonable quality, however, not in service for long.

Worked for my tank/regulator.

Not what I thought they were, a better description of the size is needed

I used these on my home beer serving system. I was previously using flat washers that the CO2 Gas Provider would sell me when I was swapping out my CO2 tank. I have always had a slow leak in my system. I gave these a try and the slow leak in my system is gone. These are the better mouse trap. I am using them on my CO2 tank regulator connection.

Stopped my co2 regulator to cylinder leak!

Regardless of the description, this washer does NOT fit "all CGA-320 fittings". I purchased this pack to use with the Kegco regulator also purchased on Amazon. My regulator CGA-320 has a large center portion that doesn't allow these washers to fit properly.

They are exactly as described and are of the highest quality I have used for the price. Will definitely be buying more!!

I live off sodastream water, but the included tank only lasts about ten days for me. I bought a 5lb external CO2 tank with a 60 inch braided steel line and adapter, which lasts about 8 weeks. After a couple years, the white seal inside the piece that screws onto the tank started to fail and no amount of Teflon tape could stop the leak. I removed the old white seal and replaced it with one of these green ones. IT FITS AND FUNCTIONS PERFECTLY! No leaks at all. Highly recommend.

The C02 Washer seal very well, and were easy to get. Great Product!

I had to remove the screw that holds the tiny filter on the inlet of the regulator because the hole is too small. If you don't have the filter on your regulator it's fine. Good seal

Did not fit my system even though it said they were compatiable
