Dive Gear Express regulator stainless steel braided flex hoses are constructed with an inner lining of High Syntactic Polyvinyl Chloride. HS-PVC is a member of the TPE family of plastics. The inner lining is reinforced with an inner sheath of braided fiber and an outer jacket of braided 316 stainless steel filament. Double braided stainless steel hoses are much more flexible, UV & kink resistant and stronger than rubber. This hose has a typical outside diameter that works with hose boots and consoles. This high pressure flex SCUBA hose has chromed brass fittings, is designed to conform to the EN 250:2014 standard, and is Nitrox Ready.

The typical HP hose is a 7/16-inch male at the end that screws into the first stage HP port and a 7/16-inch female swivel at the end that screws on to the SPG. This HP hose is { 26 in | 66 cm } long.

All high pressure hoses use an 'air spool' with two tiny o-rings to mate the swivel connector on the hose to the fitting on the gauge. With a worn or missing air spool, any HP hose will LEAK at the swivel. The air spool is not included with the hose but we recommend replacing the air spool when replacing the hose. The standard spool has the flange in the center as pictured but a few SPGs, typically the plastic body ones, may only accept a spool without a shoulder in which case you will have to reuse the air spool from the SPG.
