Adaptors / Special Fittings show info...

The Scuba Doctor has a wide range of premium quality scuba adaptors and special dive fittings from Sonar, Alpha Diving, OmniSwivel and others, for recreational, technical and rebreather divers plus the commercial diving industry.

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 find 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.
