Fittings & Tools

 

 


 

Fittings and valves of various sizes and types are necessary to supply breathing gas to the diver. The U.S. Navy standard hose in WWII was 1/2" I.D. with 1 1/16" - 17 threads. This standard was adopted by commercial diving as surplus government equipment found its way to civilian use. Low volume helmets can function well with a 3/8" I.D. hose and the fittings are usually 9/16" - 18 Oxygen (O2) fittings or JIC. The Air Hat uses the O2 fitting. Valves to control airflow, number of divers, and mixed gas are still used.
