The VALUE COLLECTION 649.31377396000 is a two-piece coolant hose nipple valve designed for use in snap-together hose systems. It features a male to female connection configuration and a POM (polyoxymethylene) body, which offers good chemical resistance and dimensional stability in low-pressure fluid-handling applications. The valve has a 1/4-inch inside diameter and a 1/4 NPT thread, making it a standard fit for coolant distribution lines. This type of fitting is typically installed by HVAC technicians, machine maintenance personnel, or plumbing professionals working on modular coolant or fluid-transfer systems.
This valve is suited for residential and light commercial applications where snap-together hose assemblies are used to route coolant or process fluids. The male x female configuration allows in-line installation within an existing hose run. The 1/4 NPT thread is a common standard in North American plumbing and HVAC systems. Sold as a 2-piece set, the valve provides a complete connection pair for a single hose junction point in a snap-together system.
Designed for use with snap-together hose systems requiring a 1/4-inch ID, 1/4 NPT male x female coolant hose nipple valve connection.
Installation is typically performed by HVAC technicians or plumbing professionals. Shut off fluid flow and relieve system pressure before removing or installing any hose fittings. Inspect mating snap-together hose components for wear or damage before installing the new valve. Follow applicable plumbing codes and the hose system manufacturer guidelines for proper assembly torque and sealing practices.
