Re: [PSUBS-MAILIST] Scuba tank hook up

Got it. In that case, I'd go with something like a scuba bottle fill yoke with a hose and fitting for your penetrator. Build an extra one of those or two to carry in your spares box. If you can rig the bottles to be accessible while the sub is in the water on the surface, then you can change them out as required, either from the deck or small boat. Just make the hoses long enough to reach, and put some kind of handles on the tanks (velcro straps and a grip, maybe?).

Sorry for the omission. The Tanks will be external and all I would need is HP. I have

regulators inside and the ability to crank em up to 250 psi. I guess what I am looking for

is yoke type with out the regulator.

External or internal? And are you set up for high pressure or not? HP air can be had with a simple yoke (like a first stage without the regulator). If you need lower pressure, then the first stage will work fine. George carried his internally, which was an issue at depth because scuba first stages can only be cranked up to about 150-160 pounds. Externally, you get that over ambient, which gives you full flow. The only other issue is flow. The 1st stage arrangement is pretty slow.

What have any of you done to hook up standard SCUBA tanks for HP air source.

Originally I was using a large steel tank. It is just too heavy to handle and I am

switching to twin Aluminum 100 tanks.

 

I am thinking a scuba first stage regulator is used with an adaptor at the thru hull

connection.

 

Appreciate any help
