Standard Pressure Double End Shut-Off Quick-Connect Couplers

These standard pressure double end shut-off quick-connect couplers are essential components for marine fluid transfer systems. Designed for shipboard hose connections, they provide a secure, leak-free seal when coupled, and automatically shut off both ends when disconnected to prevent fluid loss and contamination. Ideal for water, air, and low-pressure hydraulic lines in engine rooms, deck washing systems, and general ship service applications.

Manufactured from robust materials to withstand the demanding marine environment, these couplers offer reliable performance and long service life. The double shut-off mechanism ensures safe quick disconnection without spillage, making them a preferred choice for ship chandlers and vessel maintenance teams. Available in standard sizes to fit common hose IDs, they are interchangeable with existing systems.
