Your cart is empty. The Polyurethane 112 O-Ring seals your DIN Regulator to the DIN 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 PU90 o-ring set includes a bonus plastic o-ring pick to make changing your o-rings even easier. Don't get caught on a dive trip without an o-ring, pick up a set today.
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.

The O-Rings fit nicely on my Scuba Pro DIN. The pick was useless plastic junk that did not work -- but fortunately I have a decent Park Tools pick. Still gave the 5 stars because the O-Rings are very good quality and sealed nicely.

The pick was not strong at all. The tip of it bent right over with little pressure on it.

After trying a few incorrect size/material O-rings and losing a couple of 88g CO2 cylinders, I finally found a perfect size and material O-ring which has held for 3+ weeks now with no leaks! I full expect it to last indefinitely, as long as I'm careful and don't physically damage it when changing CO2 cylinders. Good thing there are plenty of spares in this package and a very useful O-ring pick tool as a bonus! Simply Fantastic!!!
