I posted this over at VDH but it needs to be here as well. There are several members here whom took the time to help me bring my Hydro Twin II back to life and I am extremely grateful. When people take time out of their lives to pass on tips, advice, knowledge and parts they deserve to be recognized. John Ratliff, Jerry Lang, Charles Notthoff along with Allan Klauda, The Scuba Museum and Bryan at Vintage all helped and I am thankful.

That's a great looking regulator. What years was it made?

Aquala, I am not sure of the manufacturing date as the label came to me as a reproduction and I could not find any other serial numbers to try and base it off of. Everything that I have seen so far seems to point to the years 63'-69' but that is as close as I can narrow it down. I will say we put it on the bench last night and it held 140 for about 20mins and dove very nicely but that was only to 8ft!

Hello: Is there any service manuals out there on the Internet for the Hydro twin II? I just recently purchased a Hydro twin II, You can just barely read the serial numbers on the label of 02848. I hooked it up to one of my tanks and it's leaks air. Last week in Searat showed me how to open up the Hydro twin and take out the first stage seat and the high pressure diaphragm which helped. It would really be nice if there was some service manuals out there on the Internet that we could look at. I know parts are really Scarce for these regulators but I did manage to pick up a new NOS diaphragm which is still in new condition. Next I just need to take a closer look at the first stage seat and see if that is still in good enough condition to use. Marion

If I'm not mistaken, and I know John will correct me if I am, but I b'lieve they take the same valve plunger as the Healthways. The diameter of the shaft is wrong, but here's how I fix my HW-plungers: The shaft goes into a drill chuck, which I lock into a vice, and the tip of the tool is gently touched to the cone of the plunger...

Nikeajax, The seat and plunger on mine are different then the ones you have pictured. I don't have a third party host to hold my photos or I would try to link one to show you what I have but needless to say it is different. ScubadiverBob mentioned to me awhile ago that Sportsways put three different seats and I will assume plungers in these regs. I wish I had more info but I did get the help I needed here from those I mentioned earlier.

Marion, if your soft-seat is more like the US Divers or Dacor, you may be able to polish it out: I have done so VERY successfully with both kinds. I put some masking tape on the shaft, then lock it down, GENTLY, in a drill's chuck, then lock that down in a vice. With a bit of 1500 wet-dry paper, gently touch it to the rapidly spinning seat: it doesn't take much. I tried this with a POS-Voit seat: the material they used gets very brittle over time and he high pressure blew it all to pieces when I put it back together, as I said, POS! Hope that helps? JB

It is really great to see interest in Sportsways/Waterlung! I have no info to give, just love to see more variety. Mark

Marion, before trying any polishing, lubricate the internal O-ring I showed you, as that is the most likely source of the leak. The seats are usually in pretty good shape. But this O-ring is a dynamic O-ring, which means the shaft of the seat plunger moves with each breath, and each time to turn on or turn off the air. That translates into a more rapid wearing, or drying, of this O-ring than any of the other Orings.

The 1964 Hydro Twin 11 is a completely balanced first stage.The parts for the dual air will Not work period.Sportsways made 2 different styles of Hp seats for this regulator. I just Sold Paul the parts that corrected his intermediate pressure leak.

For "pizza mind" (peace of mind) I'd replace the o-ring: lubing it up might bring it back to life, but how long has it been in there, and how much long might it last--if it fails then you get to string out chains of four letter words trying to figure it all out again--YIKES! Get a strong magnifying glass and inspect the soft-seat where it comes into contact with the hard-seat: if you find anything in that landing-area, and it doesn't take much at all, you may have damaged seat, smaller than that of the diameter of a human hair...
