looking for high pressure steel tanks.

i need hp steel tanks 80 to 130 with yoke valve. if you have some for sale let me know via PM

HP tanks with yoke valves = blown O-rings

 

[andrewy]

thank you for suggestion, i have plenty o rings

I don't think the suggestion was to carry yet more o-rings.

If you're going to be diving with HP tanks regularly, you should seriously consider converting your regulator(s) to DIN. Aside from the lower-profile connector (nice) and the stronger connection (safe), your dive shop may actually put more gas in them on a regular basis if they know you'll be connecting with DIN. They won't usually push the 3442psi limit with yoke valves, which usually means an underfill in the range of 3250-3300, filling conservatively. I have gotten a lot more 3450-3500psi fills since taking the inserts out of my valves and migrating to DIN.

pun was intended i have din MK20 too. i meant convertible yokes. din & yoke

So maybe I'll just remove the inserts, and replace them after the tanks get filled?

Or better yet spend the $50 to swap to DIN
