Air Station
Dive shops must interconnect commercial gas cylinders to create stroage banks and “scuba air stations.” This requires a variety of specialized CGA (Compressed Gas Association) hardware and fittings with appropriate pressure ratings. GMC offers a wide selection of these items. SEE PRICELIST FOR BURST DISKS ASSEMBLIES FOR INDUSTRIAL VALVES. THESE ITEMS ARE NOT PICTURED OR LISTED IN THE CATALOG.
CGA Manifold Tees and Pigtails To join a series of commercial gas cylinders of the same CGA type, MANIFOLD TEES and PIGTAILS are needed. These are usually made of brass and copper, although stainless steel is sometimes needed at high pressures or in marine environments. TEES attach directly to the CGA tank valve, thereby providing two extra CGA outlets to interconnect two additional cylinders. Interconnections are made with a PIGTAIL, a metal, looped tube (or hose) with CGA nuts on each end. Loop construction permits spacing adjustments between cylinders and also absorbs sonic vibrations during compressing operations. Pigtails can interconnect tees or go directly to a compatible CGA tank valve.

Storage Cylinder Valves GMC stocks heavy brass industrial valves for the gas cylinders commonly used by dive shops in storage banks. Each valve has a specific CGA outlet, burst disk assembly, and 3/4” NGT inlet thread. When ordering valves, you must specify the service pressure of the cylinder to get the proper, Federally required, safety disk! See price list for spare industrial safety burst assemblies (disk, washer and cap) or valve rebuild kits. ( Sherwood valves only).
