If your regulator’s first stage doesn’t have enough clearance for an air-integrated computer transmitter or high-pressure (HP) hose, the XS Scuba HP Port Extender (AC908) is the clean, reliable fix. This compact high-pressure port extender moves your HP connection outward to improve spacing, reduce crowding, and help prevent awkward transmitter positioning on tight first-stage layouts.

Built from chromed brass and sealed with Viton O-rings, the AC908 is designed for durability and dependable sealing in demanding dive conditions. It threads into a standard HP port and provides a standard HP outlet, making it a simple upgrade for cleaner routing and better transmitter fitment.

Compatibility & Use Notes

Designed for standard scuba regulator HP ports (7/16”-20)—commonly used for SPG hoses and air-integrated transmitters.

Do not use on LP ports (this is a high-pressure fitting only).

As with any regulator fitting, install carefully and perform a proper leak/pressure check before diving.
