Your cart is empty. The Polyurethane 014 O-Ring seals your Yoke Regulator to the K-Valve on both aluminum and steel tanks. Polyurethane, like Viton (FKM) is compatible with Nitrox (high oxygen content air). The difference is that polyurethane is much more resistant to puncture and abrasion than Viton, Nitrile, EPDM, and other common o-ring materials. This Captain O-Ring 10 piece 014 PU90 o-ring set includes a bonus plastic o-ring pick to make changing your o-rings even easier.
What to expect:
This item includes ten (10) o-rings and one (1) plastic o-ring pick in a resealable zip-top poly bag with "Captain O-Ring" branded packaging.
Manufactured and warrantied against defect for one year by Captain O-Ring LLC. "Captain O-Ring" is a registered trademark of Captain O-Ring LLC.

I was having an issue with the rubber o-rings tearing on the k-valve of a pony bottle. I spoke with Jon, and he recommended the tougher, poly rings. In addition to the poly o-rings I ordered, Jon added a packet of rubber o-rings (for free), just in case the poly did not solve the problem. The good news is that the poly resolved the issue, and as a bonus, I’ve got spare rubber o-rings for my other tanks. The order was filled without any problems. Thank you Jon!

The o-rings are fine. that pick is garbage. It snapped on the first try. It is cheap plastic and should NOT be sold again. I ended up having to use my dive knife to pull out the o-ring.Spend your money on a solid brass pick.
