O-ring difference Nitrox vs Standard

[Chris Stock]

I'm building a save a dive kit and getting into Nitrox. I'm going to buy from my lds, but here's my question. If I'm building one kit for both gases, do I need both rings or should I just get the Vitron rings? Or do I need both?

just use viton o-rings. Technically on a save a dive kit the only o-ring you care about being O2 clean is the yoke face o-ring and only if they're partial pressure blending. Unless you're doing staged deco then none of them have to be viton.

While I applaud you for trying to support your LDS, I struggle with spending 2x as much...

I hear you on the cost, but I make a living building cool stuff from reclaimed materials. People can buy their tables from Restoration Hardware, or me. My company has been booked 5 months out for years. I have a dozen people working for me. They own homes and have kids, I help make that possible. I like to support local small business and will gladly pay a little more for the resources they bring. If all the local shops go away, then what do you do when you need THAT piece right before your trip? But thank you for the answer to the rings!
