Purpose and key benefit Replacement vent valve core for submersible residual pressure gauges. Allows controlled venting and reliable pressure readout so your gauge gives accurate information under dive conditions. Durability for extreme conditions Rubber Oring rated to withstand temperatures from 60° to 200°, providing reliable sealing across a wide temperature range encountered in coldwater and warmwater diving operations. pressure performance Rated to 300bar peak pressure, suitable for pressure environments used in both technical and recreational diving. Maintains integrity and consistent pressure readings at elevated system pressures. Construction and longevity Metal body offers strong mechanical durability and resistance to corrosion, oxidation, and wear for long service life in corrosive underwater environments. Compatibility and integration Designed to be compatible with a wide range of pressure gauges used in technical and recreational diving, making it a practical spare or part for divers with different equipment preferences. Why divers need it Prevents inaccurate gauge readings caused by leaking or degraded valve cores. Extends the service life of your gauge assembly with robust materials and a temperature Oring. Supports safe diving by ensuring pressure information remains dependable even in extreme temperatures and pressure scenarios. Typical use scenarios Technical diving: a worn vent valve core on manifold or stage cylinder gauges to preserve accurate pressure monitoring during multitank dives. Recreational diving: Fit as a maintenance spare for singletank HP gauges to ensure dependable readings on frequent shore or boat dives. Coldwater or variabletemperature environments: Use where temperature extremes could compromise standard seals, such as polar diving, deep coldwater sites, or rapid temperaturechange conditions. Key specifications (as supplied) Oring temperature range: 60° to 200° Maximum pressure capacity: 300bar Material: metal body with rubber Oring Function: vent valve core for submersible residual pressure gauges
