Equipment – Use, Care and Repair FAQ

Do you service two-hose regulators?
I service most U.S. Divers and Voit two hose regulators for $95 plus parts and return shipping. Some service parts are no longer available. For more information, visit our regulator servicing page.

Is it safe to use a vintage two-hose regulator?
Scuba diving debuted in 1943 with the invention of the two-hose regulator, by Jacque Cousteau and Emile Gagnan. The double hose regulator was in production from about 1947 until about 1998, when Nemrod went out of business and stopped making the Snark III. The two-hose regulator was so reliable, simple, and safe, that the production lasted for over 50 years. Hundreds of thousands of divers have used them over the years, and they still have a big following today. If the two-hose regulator is properly serviced and used by a competent diver, it is just as reliable as any single hose regulator.

What is the best way to care for, clean, and store my two-hose regulator?
In my opinion, the regulator should be thoroughly rinsed in fresh water (after use in sea water). Be sure that you have the dust cap installed so no water gets into the high pressure area. Let dry thoroughly, and store in a cool, dark place. Some people use silicone products to preserve the hoses, mouthpiece, diaphragm, etc. I don’t think these products are necessary if the rubber has been cleaned, dried, and stored properly.

Is it safe to use my two-hose regulator with 3,000 p.s.i. tank pressures?
95% of the two hose regulators ever built were designed when the maximum tank pressures available were around 2250 p.s.i. or less. With this in mind, I can’t recommend using your vintage two hose regulator with more than around 2400 p.s.i. A couple exceptions are the late model Nemrod Snark III and the Voit Trieste II, which were designed for 3,000 p.s.i.
