Tank/Valve/Reg compatibility question(s).

[micklock]

You could sell the tanks on cave diver forum, some sidemount divers prefere the angled valves.

Since the advent of the 3442 E series cylinders in the US, the need for 7/8" valves have pretty well dried up. I would look around for used ones and rebuild them if price is your main consideration.

 

[Scared Silly]

i think you have most of your answers but something seems muddled.

1. I would like to change the valves as these are the weirdo angled ones. I assume that I will need 7/8" threads, so my first question is where I can buy a valve/manifold set that would work on these tanks. I wish to use them as singles until I get my dual wing and a little more training.

You have two questions here. You can still find 7/8" UNF single valves but to my knowledge the 7/8" UNF manifold is no longer being made by thermo or dive-rite. The Genesis manifold even with it crane neck is a very good manifold

My suggestion is that of others. For now, buy a couple plugs to replace the cross over while you look for another manifold to your liking. In the mean time start liking the crane neck.

2. I have a Scubapro MK2 for yoke valves. Can I use this regulator on this set, assuming I can get a DIN/yoke adapters or am I going to have to buy a new reg? I think most valves that are HP will require a DIN 300bar setup, yes?

As was said no need to buy new regs just swap your regs over to DIN and you will be good to go. You can buy DIN-to-Yoke adaptors but why bother? You will have the yoke assembles that can be used to make a DIN-to-Yoke adaptor or just swap it back when needed (this step will require a couple of tools).

I kinda like the angled outlets, I'd convert the SPs to DIN and be off and running.

 

[bighiller]

Is there anything like a pro/con to HP tanks?

Not a theoretical, but practical?

I understand some places have a tougher time partial-pressure filling nitrox and some dive boats can't top up to 3500... anything else?

 

[Bubbletrubble]

Buy the plugs, change your regs to DIN, and be happy. HP100s are great cold water tanks. Start enjoying them. That's an order!

 

[DoctorBob]

Please excuse my ignorance, but I do have a small question. Is the valve din? If so, why won't you change your regulators to din and purchase a din to yoke adaptor for vacations. Do you dive regularly at home?

Well, as for me, Most of my diving is on vacation, and I rarely dive at home. I have an old Poseidon regulator that is a 200bar din, and it does not fit this tank, and I don't think it can be converted. I guess I could convert my other yoke regs to din and get a yoke adaptor, but it sounds like too much trouble right now. I suppose If I did more local diving it might be worth it. Actually I got the tank for free, so for me it is just not worth making the change. I will probably look into selling it or trading it for a different tank.
Thanks for the suggestion, though.

I don't. I feel like I've got to be far more careful when screwing a reg in or out to avoid cross-threading (that worry may just be in my head), and they trap water much more readily than a straight valve head, so you really need to lay them head down instead of on their sides if you want to blow them dry with tank gas. I find straight valves less hassle.

I know when I tried to find a single left-hand 7/8" modular valve for one of my Asahi Genesis HP100s a couple of years ago (had to replace a damaged valve; the tanks were given to me, and I figured I'd get a left-hand so I could convert to doubles later if I chose), Thermo (or maybe it was XS Scuba) told me that they were closing out their 7/8" valves but they still had two left, for something like $130 ea. I wound up getting a left-hand Genesis valve from LeisurePro for $70 or so, plus $10-$15 for the plug.

Looking to sort out a little conumdrum I have.

I just bought a set of PST 3500psi 100cu steel Doubles w/ genesis isolation manifold (angled). So, here are the concerns/questions:

1. I would like to change the valves as these are the weirdo angled ones. I assume that I will need 7/8" threads, so my first question is where I can buy a valve/manifold set that would work on these tanks. I wish to use them as singles until I get my dual wing and a little more training.

2. I have a Scubapro MK2 for yoke valves. Can I use this regulator on this set, assuming I can get a DIN/yoke adapters or am I going to have to buy a new reg? I think most valves that are HP will require a DIN 300bar setup, yes?

Any help would be great!

I have this exact same setup and have dove them for years. Straight or angled valves have never presented a problem. Did all my tech training with a set of 100 and 120's both with angled valves.

If you want to dive these tanks as singles then order plugs. Northeast scuba supply and Leisure both had parts at one time.

You can use this reg by buying a DIN conversion about $60. If you will be diving other yoke tanks then pick up a DIN adapter for about $50.

And yest all 3500 tank valves will only work with DIN regs. No screw out insert.

1) keep monitoring E-Bay
2) ...it's a long shot, but maybe check out/reach out to vintagescubasupply.com or it's counterparts in the vintage scuba gear reseller market......maybe they can make inquiries for you or keep their eyes peeled for ya....
