2 first stages plus one hp hose = transfill whip?

[RogerDodger]

If I have 2 Aeris A1 first stages... and say a 6' HP hose can I connect both ends of the HP hose to the HP ports and create a transfill whip to fill LP tanks? Or is there some sort of mechanism that prohibits reverse flow in first stages?

no mechanism to prevent reverse flow, but it would take a very long time to transfill any volume as the opening in the HP hoses are very small.

Deluxe Cylinder Equalizer with DuoKev HP Hose - Northeast Scuba Supply Store
Much better way to go about that

A pair of "paintball yokes" ($9.99 ea), one fill hose, and a double male QD fitting does it for much less (DIN fill adapters or valve plugs are necessary too if you are DIN).... likely less than $50.00

Where can I get paintball yokes for cheap?

got mine off the auction site you "can't mention here"....

As well as being time-wise impractical, that would be one expensive transfill whip. They can be bought for less than the cost of a first stage.

Lynne, not quite true, Piranha has a few under $100, I think the one I'm using for my O2 bottle was $60 brand new, but that's an anomaly. Works really good for O2 though... Balanced piston O2 clean for that cheap was a great deal

I don't think a hp hose will thread into the reg. Perhaps a couple of spg hoses with a coupler might work.

It can be done pretty cheaply: http://www.scubaboard.com/forums/do-it-yourself-diy/354001-tank-equalizer-2-50-a.html?highlight=whip

But not very quickly if you are talking about moving larger volumes of gas. Best used to put a puff in an emply tank or top off a pony.
