Where can I get a green colored ring for my RG2500 first stage? I've seen a few people with them on o2 bottles and on Optima's. I'd like to put one on my o2 reg. Can you let me know where I can order one from?
the green ring is used on the optima to distinguish the O2 first stage. it is set for a much lower intermediate pressure than the standard regs to reduce power drain from the O2 solenoid. I'm sure any DR dealer can get one for you.
hmmmm, I can't find it either... the normal red logo ring doesn't even have a part number in the service manual. weird. I guess if you want the green ring you've gotta get the CCR first stage part #RG1208‐CCR. just remember to set the IP up to 140 before you try to use it...
The green (or red) ring is not for sale separately. We do this purposefully so that we can distinguish green first stages as those with 90psi intermediate pressure rating vs. 140 psi for regular first stage. We receive the first stages with those rings from our OEM and do not sell the rings separately.
You could put a green cap on the first stage or mark with green nail polish if you need an easily recognizable mark for your o2 reg.
