Dixon Valve Coupling MSC1440510K Barbed Hose Fitting

Product Description

The DIXON VALVE COUPLING MSC1440510K is a brass barbed hose fitting designed to connect flexible hose to threaded ports in fluid-transfer and hydraulic plumbing systems. It features a 5/16 inch hose inside diameter barb on one end and a 5/8 inch UNF female 45-degree SAE swivel on the other, creating a leak-resistant mechanical connection without the need for welding or brazing. The all-brass construction resists corrosion in water, oil, and light chemical service. The 45-degree SAE swivel end allows for angular alignment during assembly, reducing stress on hose lines. This fitting is installed by licensed plumbers and fluid-power technicians in both commercial and industrial settings.

This fitting is suited for residential and light commercial plumbing, hydraulic lines, and fluid-transfer applications where a 5/16 inch ID hose must terminate at a female threaded port. The 45-degree SAE swivel accommodates routing in tight spaces and reduces hose bending stress at the connection point. It is commonly found in equipment plumbing, irrigation sub-assemblies, and low-pressure hydraulic circuits. The hex head allows standard wrench tightening, making installation straightforward in confined areas. Sold individually.

Installation Notes

Installation should be performed by a licensed plumber or qualified fluid-power technician. Depressurize and drain the system fully before removing or installing any fittings. Use a properly sized wrench on the hex head — do not use pliers directly on the hose barb shank. Verify hose inside diameter and outside diameter compatibility before assembly, and inspect the barb and swivel seat for debris or damage prior to installation.
