Need an extra high-pressure (HP) port on your first stage? The XS Scuba AC906 HP Port Adapter (often called an HP splitter) lets you turn one standard 7/16”-20 HP port into two HP ports, making it easy to run an analog SPG and an air-integrated (AI) transmitter at the same time—especially helpful on regulators that only have a single HP port.
Built from durable chrome-plated brass and fitted with Viton O-rings, this compact adapter is designed specifically for high-pressure applications and is rated up to 5000 PSI. It’s also cleaned for use with up to 40% pre-blended Nitrox, making it a solid choice for everyday recreational setups and many travel rigs.
