45 degree tank valves???

[Wiznutaggie]

I’m buying a set of tanks from a guy this week (hp119s) and he also has these hp100s that I’m thinking of buying. They have these 45 degree looking valves on them that I haven’t seen before. What’s the story with this style of valve?

Not sure there is a story. Genesis branded valves in the early to mid 90’s were angled. I’m thinking the idea was that the regulator was less likely to hit your head if the valve was angled.

I suppose, although I can’t see how the angle would really help much. Were they normal 3/4 threads if one wanted to change them?

Early technical regs weren't made with fifth ports and swivel turrets. These made hose routing much easier on Poseidons and DS4 first stages.

They look like 3500psi HP tanks with 7/8"-14 UNF threaded necks.
Nothing wrong with them, all of my steels are PST/Sherwood/Genesis 100s/120s.
But ...
New valves are avail, but pricy and getting harder to find, and some parts (valve stems) for the Genesis valves that you are asking about are not really available at this point.

Newer HP steels are 3442psi and use larger "standard" sized 3/4" NPST valves.

Great info! Thanks y’all. Good to know the valves are costly to replace / hard to fix. That helps my purchasing decision a lot!

They won't take a yoke regulator.

Not hard to fix unless the stem-threading is buggered-up.
Service parts are otherwise readily available from Northeast Scuba Supply
I have those same valves (currently manifolded on 100s). The left right pair, especially with the isolator crossbar are sought after by those who have 7/8 necked tanks for doubling.

One other important note. The 7/8 valves (with rainbow unicorn exceptions) can only be used with 300 Bar DIN regulators.

I have some doubles with that config. I have had these for roughly 25 years or so and they have held up well.

Now the decision became harder again lol. I've got 300bar din regs, so no issue there. Guess it depends on price then. What's a good price on these older tanks?
