Key benefits Reliable venting for both technical and recreational diving pressure gauges, ensuring stable performance in underwater environments. Secure connections with a 7/1620 UNF thread and a peak pressure rating of 300 bar to handle demanding dives. Designed for residual pressure pipes with a rubber O‑Ring rated for 60°C to 200°C, providing oxidation and wear resistance for longlasting use in varied diving conditions. Compact, lightweight construction: body size 18 x 9 mm (0.7 x 0.35 inch), diameter 4.2 mm (0.16 inch), net weight 2 g, finished in silvercolored metal for easy integration into diving gear. Safe, controlled air release mechanism that prevents pressure buildup during ascents and descents, focusing on user safety and equipment reliability. What it fits and key specifications Thread: 7/1620 UNF for secure connections to compatible gauges and fittings. Peak pressure rating: 300 bar, suitable for demanding diving scenarios. ORing: rubber ORing designed for temperature range 60°C to 200°C, with oxidation and wear resistance. Material and finish: Made from For Lasting metal in a silver color. Size and weight: 18 x 9 mm body, 4.2 mm diameter, net weight 2 g. Function: Vent valve core mechanism enables controlled air release to avoid sudden pressure changes. Mechanism and safety The vent valve core provides controlled air release to prevent pressure buildup. Designed to support safe operation during ascents and descents and to enhance overall equipment reliability in diving environments. Use scenarios Technical dives requiring reliable venting of gauge air to prevent pressure buildup during ascent. Recreational dives where compatible with residual pressure pipes and need for a durable, temperaturetolerant ORing seal. Replacement or upgrade of gauge vent components in diving gear, ensuring compatibility with 7/1620 UNF fittings and consistent performance across varied conditions.
