XS Scuba Thermo J Valve

Thermo J Valve – Military-Style Reserve Scuba Cylinder Valve with Convertible DIN/Yoke Outlet

The Thermo J Valve is a rugged reserve-style scuba cylinder valve modeled after the same J-Reserve valve system used by military divers. Designed to provide a mechanical reserve air function, the valve allows divers to access a reserve gas supply when cylinder pressure reaches a predetermined level, offering an additional layer of gas management capability.

Finished with a durable black PVD coating for enhanced wear and corrosion resistance, the Thermo J Valve features a PRO outlet with a removable spin-out DIN insert, allowing quick conversion between standard yoke and 230 bar DIN regulator configurations. Cleaned for use with pre-blended Nitrox mixtures up to 40% oxygen, it is suitable for a variety of recreational, professional, and specialty diving applications. At Oceanwide Outfitters, we recommend the Thermo J Valve for divers seeking a traditional reserve valve system with modern regulator compatibility.
