Those regulators belong on the wall as a memory of bygone days. I never had the described problem with my aquamasters in 15 years of using them in the Navy. Aftermarket parts and makeshift parts will kill someone. When the single hose US Divers Conshelf came out they were much less problems and I still use the US Divers single hose with the metal second stage. Just my opinion not knocking the old double hose so easy to exhale and just lay back to get an easy inhale. Yes I got one on the wall Be careful.

No offense but you have no idea what you are talking about. Modern reproduction parts are as good as the OEM part of today and better than those from the day. Like any modern reg, properly service and dove, they are as safe and frankly more dependable than modern regs. I restore, service and dive these regs on a regular basis so I am well aware of how they perform and the quality of the reproduction parts.
 
Herman. Come on I built those regulators for 30 navy and civilian divers for two years . And like I stated never had the stated problem. Just assumed it was after market parts. Plus I finished by saying it was just my opinion. You must have something to loose by my JUST saying comment. Sorry if I offend or hurt your business.

I have nothing to lose, I don't make or sell the parts. I just do not like blanket statements like "Aftermarket parts and makeshift parts will kill someone." That is pure BS based on nothing but dive shop hearsay. You may have rebuilt them in the past, I still do and have been for a number of years so I know the current parts well.

Whatever. I think some people need to hang themselves on the wall. N
 
No, I reinstalled a used OEM seat.
I had same problem but different cause.

The hint was meant for the op. I used your quote, but changed seat to diaphragm. Thought it might help him.
 
My problem wasnt the seat or the diaphram it was the pin length. also in regard to these things being old and dangerous ...i call bs on that. ALL regulators made whether the top of the line newest or the old double hose are mechanical devices. Parts can fail,break, be out of spec (even brand new out of the box). This dont make them unsafe. Thats why we disassemble, test, pressure test, breathe test, then use this equipment. For what its worth id trust some of the very sturdy made metal parts over this new plastic crap any day. I have had my DH down to 150 feet and it breathes just as good as any modern stuff you got out there. The way they are made they dont freeze up in cold water either. So if you think this DH stuff is just "for hanging on the wall" go post and contribute to gear you like to use. Offer something positive or dont say nothing at all.
 
It sounds to me that something is "fishy" with the assembly of this regulator. There should be "no way" the properly assembled DA Aquamaster (or its variations, including the Conshelf, which uses the same parts in the first stage) can fail in this manner. The parts diagram shows part #1000-27, "pin support" being what touches the diaphragm, NOT the pin (#1000-25). This pin support is a metal disc that pushes against the diaphragm from the pin side. On the other side of the HP diaphragm is part #1000-39, another metal disc that supports the spring. No other parts should be against the diaphragm. this is a metal disc-diaphragm-metal disc design which should preclude this described failure from accurring. My question is whether the regulator has these "safety critical" parts?
