Dixon Valve Coupling 10684 Hose Coupling 1 in Npt

Product Description

The DIXON VALVE COUPLING 10684 is a universal hose coupling designed for use with 1-inch NPT threaded connections. Constructed from malleable iron, it provides dependable strength and resistance to mechanical stress in demanding service environments. Both ends feature male NPT threading, making this coupling compatible with standard pipe and hose fittings across a wide range of fluid-handling applications. Licensed plumbers, pipefitters, and industrial maintenance technicians commonly install this type of fitting in water, air, and general-service fluid lines where secure, leak-resistant connections are required. This listing is sold as a pack of 5 couplings.

This coupling is suited for residential and commercial plumbing, HVAC hydronic systems, irrigation lines, and industrial fluid transfer applications that call for 1-inch NPT male-threaded hose end connections. The malleable iron construction makes it appropriate for moderate-pressure service in both above-ground and accessible indoor installations. It is a general-purpose fitting used by plumbing and mechanical contractors who need reliable, code-compatible hose end hardware on hand in quantity.

Compatibility

Designed as an OEM-style replacement or installation fitting for systems using 1-inch NPT-threaded hose end connections in plumbing, HVAC, and general fluid-transfer piping.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing codes such as the IPC. Shut off the water or fluid supply and depressurize the line completely before removing existing fittings or installing this coupling. Apply appropriate thread sealant or PTFE tape to the male NPT threads before making up the joint. Do not overtighten malleable iron fittings, as the material can crack under excessive torque.
