The Scuba Doctor offers a large variety of low pressure (LP) first stage regulator port adaptors for recreational, technical, rebreather, sidemount and commercial diving applications.
Most low-pressure hoses are 3/8-inch male and most first stage low-pressure ports are 3/8-inch female. A few brands of first stages have a special low-pressure port that is 1/2-inch female, notably some Apex and older Aqualung models. We offer 1/2-inch to 3/8-inch adaptors.
Reminder: The actual configuration of an adaptor is a mirror image of its use. A 3/8"-24 UNF FEMALE port requires a 3/8"-24 UNF MALE adaptor etc. In technical diving operations where many fittings may get co-mingled, be sure that all adaptor combinations can accommodate the intended flows and pressures.
Looking for a particular fitting you don't see here? Let us know and we'll see if we can order it for you.
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.
