Metal Quick Connector for Ø12 mm Hose with 1/2" Female Thread

This female connector Ø12 mm with a 1/2" internal thread is designed for larger, more demanding systems where higher flow and strength are required. Thanks to the wider 1/2" port, it allows more air or fluid to pass with less restriction, making it favored for applications such as marine toilets, ballast systems, or cooling circuits. The metal build is resilient to shocks and stresses – the connector won’t easily break if the hose is accidentally tugged or stepped on.

Applications:

• Marine Sanitation Systems: On many boats, hoses for toilet discharge or bilge pump-out are 1/2" and require reliable connectors. This connector can be installed at the inlet of a Y-valve or waste pump, allowing you to quickly disconnect the hose when servicing the system or switching between holding tank and overboard discharge (in conjunction with an appropriate Y-valve).
• Ballast and Water Tanks: In water transfer systems (ballast tanks, fresh water tanks), the 1/2" coupler enables fast hookup of hoses for filling or draining. For example, you can swiftly connect a portable pump to a tank via this quick coupling, saving time when prepping the boat.
• Industrial Use: In workshops and industry, 1/2" quick couplings are commonly used for high-flow pneumatic tools or cooling systems. This connector suits fixed mounting on equipment where hoses need rapid detachment – e.g., on a wall air manifold or a machine’s coolant port that periodically has hoses attached.

Best Practices: Pair it with the Ø12 mm male connector, 1/2" M (code 04891) – together they form a complete set. For optimal flow, ensure the quick-release mechanism is clear of debris. If leaving unused for extended periods, cover the connector with a cap or plastic wrap to prevent dust and salt intrusion. This 1/2" connector is most suitable for medium to large boats (roughly 7+ meters), where systems are more complex and pressures higher.
