It depends on whether they're Genesis high pressure tanks or not.

High pressure tanks take a weird, 5/8" thread, and are for strokes.

Real tanks all take the same thread.

7/8" Machine Thread... not just Genesis, but PST as well.

Until this year when PST made the HP tank debate a thing of the past
by making it officially okay to overfill your 104s :)

Now the only stroke tanks left are Catalina, Asahi, and those stupid
PST 3000 psi steel 80s.

That would be the tank manufacturer that never used an inferior aluminum
alloy, right?

I've never heard of these. What name to the market under?

I"m not aware of these either, but PST just released some pretty cool steel
100's with a standard thread neck. I've got two of them which work as well
as any of my other DIN tanks and, once I confirm the capacity of the yokes
on my regulators, should work pretty well with them also, which is, of
course, the attraction.

Genesis and Sherwood's current HP cylinders are Asahi.

Surprised the hell out of me... saw a steel tank sitting in the shop
and thought the size looked a little odd for a steel tank. Looked
closer and sure-nuff, it was a 3000psi PST 80.
