Dixon Valve Coupling 1840504A Reusable Female Hose Fitting

Product Description

The DIXON VALVE COUPLING 1840504A is a reusable female hose fitting designed for secure, field-serviceable hose connections in plumbing and fluid-handling applications. Threaded to a 1/4 inch NPSM standard, this fitting accepts hose with a 5/16 inch inner diameter. The reusable design allows technicians to disassemble, inspect, and reinstall the fitting without replacing the entire assembly, reducing material costs on the job. Weighing 0.1 pounds, the 1840504A is a compact, lightweight component suited for professionals who need reliable threaded female connections in tight spaces or high-cycle service environments.

This fitting is appropriate for residential and light commercial plumbing, fluid transfer lines, and equipment hookups where NPSM female threaded ends are required. It is commonly installed by licensed plumbers and pipefitters working on water, air, or compatible fluid service lines. The 5/16 inch hose ID sizing makes it a practical choice for small-bore hose assemblies where a reusable, field-assembled connection is preferred over a permanently crimped end.

Compatibility

Installation Notes

Installation is typically performed by a licensed plumber or qualified pipefitter. Shut off fluid supply and relieve line pressure before disassembling any hose fitting. Inspect the hose end for cuts, abrasion, or deformation before installing the reusable fitting. Follow applicable IPC or IFGC guidelines for the specific fluid service and ensure thread engagement meets standard practice for NPSM parallel threads.
