yoke on hp?

[awills101]

what is the yoke on the first stage rated to? im about to switch to an hp steel tank (3442) and was wondering if i had to switch to din?

You can use a yoke on a HP tank. Yokes can be used on tanks up to roughly 3450 psi which is why the newer tanks do not exceed this rating.

I think it is going to depend on the yoke. Yours may be marked to indicate the maximum pressure.

Many new yokes are marked for 3500 psi but there are a lot more rated for 3000 psi. The very old yokes were probably designed for LP tanks and, perhaps, 2500 psi.

If yous isn't marked, I wouldn't assume it is rated 3500 psi.

So, I sent 4 Oceanic first stages in to the LDS and had them install DIN fittings. Problem solved! It cost me $75 per stage for conversion.

alright thanks, i just wanted to make sure before i bought the tank

Modern yoke first stages will do fine at 232 bar (which equals 3365 psi, close enough for guvamint work).

you are good to go
DIN is a more secure connection, but if you travel, can be a little problematic as yoke valves are a more "universal" valve.

ill check mine, its a newer reg so hopefully it'll be 3500, its an atomic z2

In that case, there are adaptors DIN->yoke that exist.

They do exist, and I have one, but I never liked it because it pushes the first stage too close to the back of my head.

OBTW, I'll sell the one I have if anyone wants it!

You can use a yoke on tanks rated to 3440 psi but I would not recommend it. I have seen too many o-rings extruded out of such connections at those pressures. A DIN connection is much more secure.
