100 Polyurethane CO2 / HPA Tank O-Rings (90 Durometer) [RED] - Replacement Urethane orings for Paintball co2 / high Pressure air Tanks

Not great for internal parts, works on co2 tanks just fine though

This purchase was much needed in order to rebuild classic paintball markers. My son and I are updating and replacing old rotted parts. Thanks to the easy purchase and very fast shipping of these high quality enexpensive orings I am able to get my old gear back into the game. After a 20 + year break, I am so excited to be playing again this time my 13 year old son, that is my paintballing buddy. We are now rocking the local fields here in the Kansas city area.Thank you.

They fit without falling apart when you take the tank off.

So far the O rings have done their job as expected.

Fast shipping, Great Price

This bag FULL of O-rings came for a decent price.But, since it was a decent price, these can't be considered "high end" rings. There are quite a few (almost all of them) with significant flashing left over from the molding process.That said,paintball tanks don't require a super expensive and perfectly made O-ring. All they have to do is fit around the threaded end and mate with the inside of the ASA. The pressures aren't that high and the tolerances or not very strict.So, while I ding the manufacturing quality of the rings, I also think they are more than adequate for service in the paintball field. We're not building jets or performing brain surgery with these things. All in all, this bag is a good deal on a perfectly acceptable product.

I couldn't ask for a better o-ring.

Fit right on my tank and ran it with no issues so far
