Dixon Valve Coupling 1260504C Barbed Hose Fitting Brass

Product Description

The DIXON VALVE COUPLING 1260504C is a brass female barbed hose fitting designed for secure, leak-resistant connections between threaded pipe and flexible hose. It features a 1/4 inch female NPSM swivel thread on one end and a 0.3125 inch barb sized for 5/16 inch inside diameter hose on the other. The swivel design allows the fitting to rotate during installation, reducing hose twist and making hand-tightening easier in tight spaces. Brass construction provides corrosion resistance and durability in both liquid and low-pressure pneumatic applications. This fitting is installed by plumbers, irrigation technicians, and general maintenance trades in water supply, fluid transfer, and light industrial systems.

This fitting is suited for residential and light commercial plumbing, irrigation, and fluid-handling setups where a 5/16 inch ID hose must connect to a 1/4 inch female NPSM threaded port. The hose barb gasket seat design creates a reliable seal when used with a compatible hose barb insert and clamp. It is commonly installed on equipment fittings, manifolds, and inline connections where a swivel female connector simplifies routing and assembly. No specific model compatibility data was provided in the source information.

Installation Notes

Shut off fluid supply and relieve system pressure before removing or installing any hose fitting. Thread the female NPSM swivel end onto the male port by hand first, then tighten with a wrench to the fitting hex — avoid over-tightening brass threads, which can crack or strip. Seat the barb end fully into the hose and secure with an appropriately sized hose clamp. Follow applicable IPC or local plumbing code guidelines for the intended fluid type and pressure rating.
