US Divers Pro Diver 1st Stage........

[DOWNDEEP73]

I was given a US Divers Pro Diver 1st Stage. I would like to try to have it rebuilt. Some where I read that the Pro diver 1st stage had Conshelf internals and the parts were interchangable. Does anyone know what other models have the same internal parts?

I was thinking that the Conshelf 20, 21, 22, XIV, XIV Supreme has the same internals.....Can anyone confirm this?

As far as I know all USD/Aqualung diaphragm regulators going back to the early 70's all use the same HP seat and balance chamber o ring.
You will have no problem getting your "spaceship" serviced.
The only problem you might run into is having to use 1/2" to 3/8" adaptors if you have to replace LP hoses, especially difficult to find a 1/2" inflator hose.

Just using it for a pony bottle.
You're right it does look like a "Spaceship".

They actually started around 1965 with the Royal Aqua Master double hose regulator…then in the Conshelf and all the way to the latest Titan and others.

I do believe they use the same seat in all their diaphragm regulators...Which is great way of guaranteeing parts availability.

Thanks guys!
I am going to take it to my LDS which is an AquaLung Dealer for service.
