What are you going to do with them?
Put them on tanks. :brickwall
I should have been more specific. Are you going to invert the tanks on the revo?
No, I am in the middle of a super secret, classified, scientific, innovative, world class, original, experiment.
I'm sure it's overkill, but the Lola valves have one knob on top and one on the side, each controlling one DIN outlet. I guess you could plug one outlet.

That sounds like the beginnings of an "expedition"...
