The Scuba Doctor offers a large variety of high pressure (HP) first stage regulator port adapters and hose converters for instrumentation installation, plus technical and rebreather diving applications.
Most high-pressure hoses are 7/16-inch male and most first stage high-pressure ports are 7/16-inch female. A few brands of first stages use high-pressure ports that are 3/8-inch female, notably very old models from the early days of diving. We offer 3/8-inch to 7/16-inch adapters.
Reminder: The actual configuration of an adaptor is a mirror image of its use. A 7/16"-20 UNF FEMALE port requires a 7/16"-20 UNF MALE adapter etc. In technical diving operations where many fittings may get co-mingled, be sure that all adapter combinations can accommodate the intended flows and pressures.
We reserve the right to limit order quantities to less than 10 pieces because our supply is appropriate for the demands of individual divers, but not bulk orders. Large volume bulk orders will NOT qualify for our free shipping promotion.
