Can anyone tell me if the o ring on regs (the internal one that holds bottle and reg together whilst pressurized) is a standard size on all regs?Obvious follow up question (if answer is yes) is what size is this?
not always, the oring depends on whether your bottle has a deep chamfer or a shallow chamfer on the opening. As for size, i don't know but contact HPAC, their number can be found at www.hpac.co.uk and they will be able to tell you
Dunno if it'll help but when mine split, I dug a similar one out of my ion spares kit and it worked like a charm, so they must be pretty widely used in that size for various purposes
They are a bit fatter normally...I chnaged teh one on my Stako coz it was leaking around the neck...pretty sure it was either an Ego or Shocker o-ring that I used.
