Trident 2nd Stage to 1st Stage Adjustment Adapters

Match a compatible scuba regulator first-stage port to a hose with a different thread size using the selected Trident thread adapter. These compact fittings are intended for specific low- or high-pressure connection changes and should be chosen by exact model and thread direction, not by appearance alone.

• AA48: 1/2-inch male to 3/8-inch female low-pressure adapter
• AA49: 3/8-inch male to 1/2-inch female low-pressure adapter
• AA50: 7/16-20 male to 3/8-inch female high-pressure adapter
• Compact metal adapter construction

Critical compatibility note: Low-pressure and high-pressure regulator connections are not interchangeable. Confirm the selected model, male/female thread direction, port type, hose fitting, working pressure, sealing method, and regulator manufacturer's requirements before ordering. Installation and leak testing should be performed by a qualified regulator technician before diving.
