Product Description What it is A replacement submersible inflation valve designed for diving bags and related water equipment. Made from durable PVC with built-in vacuum and pressure-relief features to deliver safe, reliable inflation and protection for your gear. Key benefits — why you need it Reliable inflation: Provides secure, consistent air transfer so you can inflate lift or dry bags without leaks or unpredictable airflow. Enhanced equipment protection: Integrated pressure relief valves protect the submersible gearbox and valve assembly from overpressure and impact, reducing the risk of breakage. Stable, error-free pumping: Valve design prevents unintended backflow or “surfing” during pumping, so you can add air precisely and maintain controlled buoyancy. Long-lasting durability: Constructed of wear-resistant PVC, the valve resists abrasion, saltwater corrosion, and repeated use for dependable performance dive after dive. Important attributes Function: Replacement inflation/deflation valve with pressure-relief and vacuum capabilities for secure air management. Material: High-quality, durable PVC for wear resistance and extended service life. Performance: Lightweight yet robust; designed to preserve gearbox integrity and prevent air loss or uncontrolled inflation. Compatibility: Intended as a direct replacement for inflation valves used on diving bags and other water equipment (use existing fittings and mounting points where applicable). Practical use scenarios Inflating lift bags during underwater recoveries: Pump air confidently without backflow so the bag reaches target buoyancy and protects recovered items. Replacing a damaged valve on a dry bag or buoyancy device: Restore safe inflation and prevent pressure-related damage to the internal valve assembly. Surface topping-up and emergency inflation: Lightweight valve construction and pressure relief help you add air quickly and safely when adjusting buoyancy or handling unexpected situations. What to expect Secure fit for inflation tasks, pressure management to safeguard internal components, and long-term wear resistance. Ideal as a direct replacement part to restore safe, predictable inflation performance in diving bag systems and similar water equipment.
