Combo Cylinder Valve and Piston First Stage by H2Odyssey
Streamline Your Backup System
Combine your cylinder valve and first stage into one ultra-compact unit. The H2Odyssey Combo Cylinder Valve and Piston First Stage is the ultimate space-saving solution for your technical diving rig. By integrating an unbalanced piston first stage directly into the tank valve, you eliminate the need to mount a separate regulator, keeping your profile incredibly clean. This makes it an ideal choice for drysuit argon inflation setups and redundant pony bottle systems.
Compact and Capable
Despite its small footprint, this combo valve delivers everything you need to run a backup system safely and efficiently. It features a large, easy-to-use on/off knob and a built-in over-pressurization valve (OPV) for added safety. The block is machined with two standard 3/8" low-pressure (LP) ports and one 7/16" high-pressure (HP) port, giving you plenty of routing options for an SPG, inflation hose, or backup second stage. With standard 3/4" NPS threads, it easily fits most standard scuba cylinders.
Important Filling Requirements
Because this is an integrated unit, you do not remove a first stage to fill the tank. Instead, it utilizes a dedicated high-pressure fill port equipped with a 7.8mm male nipple.
Please note: A dedicated fill adapter (sold separately) is required to fill the cylinder while this combo valve is attached.
