tank valve o-rings

[ROCK HUNTER]

I am diving with a yolk connection on my apex regulator. 130 hp tank does any one know what pressure would be safe. Is 3700psi unsafe ??? Have logged 15 dives to 135ft I also carry a 20cf pony.

You are definately safer if you convert to a din fitting on your regulator.
You are above the pressure rating for a yoke to O ring connection.
You can extrude an O ring easy enough at lower pressures.
Be smart and make the change. Cost you maybe $50. Cheep insurance.

yeah i would have to agree with capt gene.
