Corrosion-Resistant BCD Pressure Gauge Valve Insert with O-Seal for Diving Hose Connections

This compact diving gear component is designed as a BCD valve part for pressure-gauge hose connections, helping keep your underwater setup complete and serviceable. Built as a diving inflator valve insert and high pressure hose valve insert, it supports stable air supply transfer in the hose connection area during diving use. The O-seal sealed structure helps the BCD pressure gauge valve insert sit securely, supporting a tighter fit and reducing the chance of unwanted leakage. Its corrosion-resistant metal body is made for regular underwater training and everyday dive maintenance, giving divers a long-lasting replacement part they can rely on. Measuring about 9 mm in outer diameter and 18 mm in length, this small insert is easy to carry as a spare and helps keep your BCD hose connection ready for use.
