Yep.By "standard" I meant the sizes you can freely buy form an o-ring supplier.
Should be no problem.By the way, Apeks uses EDPM duro 80 o-rings. It it safe to replace them with Viton duro 90?
I can't believe how long I've been diving that just very recently I started to explore the o-ring world. I was having problems with tank valves so I was looking through tech manuals. Thermo and XS valves both have J valves and k and Pro delux but not all orings fit the channel exactly. Aqualung has a j valve but there are two different size yoke and the manifold uses a thicker oring. Then there is the o-ring industry. Japanese use JIC system the british use BS which is metric. The aero space industry uses AS568 which means everyone has their own part numbers. XS and Thermo uses 2 different for the same o-ring for the size 014 which is the most common yoke size. Then there's the application to consider. If you dive in pools the chlorine eats the rubber but Viton is chlorine resistant because it has chlorine in it. The the durometer matters if you are diving with high O2 because it's thinner than air. The wrong o-ring could slip out. So if you have different gear you can't just match the size and think you have the right o-ring. Always use the tech manual part and hunt down that specific o-ring.Hello.
Can anyone tell me if the o-rings used in Aqualung/Apex regulators (1st and 2nd stages) are of standard sizes or they use some proprietary parts?
Thank you.
