Yes
Yes, Those are aqualung numbers and I have a friend that works for a dealer and gets his stuff from him.. I order my kits form
http://vintagedoublehose.com/ as Aqualung will not sell to you unless your a dealer.. Most of the guys that work on regulators just buy O-rings bulk .. As they are just O-rings..
I'm going to try and help you out... DON"T BUY A Conshelf... Buy the "XYZ" regulator you like that's there top of the line flagship one... Have it serviced every year and this way you'll get " Parts for Life " if they offer that..
I'n fact, The regulator you have right now is a great one.. No need to buy a new one, Unless it's beat up.. And has not been taken care of...
I've done all I can do here...
