Submersible residual pressure gauge vent valve core Key benefits Reliable pressure monitoring: Designed for submersible residual pressure gauges, this vent valve core delivers accurate, repeatable pressure readings so divers can monitor tank pressure with confidence. Durable in extreme conditions: A rubber Oring resists temperatures as low as 60° and as as 200°, plus oxidation and wear, extending service life in harsh environments. Built for underwater use: Metal construction provides strength and corrosion resistance for longterm, dependable performance under demanding dive conditions. pressure capability: Rated to a peak pressure of 300bar to match both technical and recreational diving systems. What it does and why you need it Replaces or upgrades the vent valve core on your submersible residual pressure gauge to restore reliable sealing and measurement accuracy. Prevents leaks and signal errors caused by worn or damaged valve cores and Orings, reducing the risk of unexpected gauge failure during dives. Works with a wide range of diving pressure gauges, making it a practical maintenance part for divers, dive shops, and equipment technicians. Features and specifications Function: Ventilation/vent valve core for submersible residual pressure gauges. Material: Metal construction for strength and underwater durability. Seal: Rubber Oring resistant to oxidation and wear. Temperature tolerance: Operates in temperatures from 60° up to 200°. Pressure rating: Peak 300bar. Compatibility: Suitable for technical diving and recreational diving pressure gauges. Typical applications Technical diving: Use in pressure systems where precise, durable pressure monitoring is required for extended or deep dives. Recreational diving: deteriorated valve cores on recreational gauges to maintain safe and accurate tank pressure readings. Equipment maintenance: Handy spare part for dive shops and technicians performing routine gauge service, inspections, or repairs. Installation and use notes Intended as a directfit replacement for compatible submersible residual pressure gauge vent valve cores; follow manufacturer installation procedures for your gauge. Inspect Oring and metal components regularly for wear or damage and as part of routine maintenance to ensure reliable performance.
