Lock Type Air Hose Coupling — IMPA 351011-351014

Lock type air hose couplings are essential for reliable pneumatic connections on board cargo ships, container vessels, tankers, and offshore support vessels. Used in engine rooms, workshops, and deck air stations, these quick-connect fittings allow crew to rapidly attach or detach air hoses with a simple quarter-turn, minimising downtime during maintenance and operational tasks. The secure lock mechanism prevents accidental disconnection under pressure, enhancing safety in demanding marine environments.

This series covers four individual IMPA codes (351011 through 351014), each available and priced separately to suit various hose sizes. Manufactured from cast brass with an optional copper-plated finish, the couplings offer excellent corrosion resistance and durability. They are rated for working pressures up to 150 psi (10.3 bar) and operate effectively across temperatures from -20°C to 80°C (-4°F to 176°F). Each set includes both male and female hose ends, ensuring a complete connection solution. The quarter-turn lock design provides a secure, leak-free seal for all types of air and pneumatic service.
