Dixon Valve Coupling MSC1430612K Barbed Hose Fitting

Product Description

The DIXON VALVE COUPLING MSC1430612K is a brass barbed hose fitting designed for fluid transfer applications requiring a secure, leak-resistant connection between a hose and a threaded female port. This fitting features a 3/4-inch UNF female swivel end with a 45-degree SAE or 37-degree JIC seat and a 3/8-inch hose barb end sized for hose with a 3/8-inch inside diameter. The brass construction provides corrosion resistance suitable for water, oil, and fuel service. It is installed by plumbers, hydraulic technicians, and industrial maintenance professionals in both shop and field settings.

This fitting is suited for low- to medium-pressure hydraulic and fluid transfer lines where a hose barb-to-female swivel connection is required. The 45-degree SAE or 37-degree JIC swivel seat allows for flexible positioning during assembly, reducing stress on the hose. Typical applications include hydraulic return lines, lubrication systems, fuel delivery plumbing, and general industrial fluid circuits. The fitting accepts hose with a 3/8-inch inside diameter and a nominal 1/2-inch outside diameter.

Key Features

• Brass construction for corrosion resistance in water, oil, and fuel service
• 3/8-inch hose barb fits hose with 3/8-inch inside diameter and 1/2-inch outside diameter
• 3/4-inch UNF female swivel end with 45-degree SAE or 37-degree JIC seat
• Swivel design allows angular adjustment during assembly to reduce hose stress
• Hex head size of 0.875 inches for standard wrench installation

Compatibility

Designed as a standard hose barb-to-female swivel connector for hydraulic and fluid transfer hose assemblies using 3/8-inch inside diameter hose with a 3/4-inch UNF female threaded port conforming to SAE 45-degree or JIC 37-degree flare seat standards.

Installation Notes

Installation is typically performed by hydraulic technicians or plumbers using an open-end or adjustable wrench on the 0.875-inch hex head. Depressurize and drain the system fully before removing or installing any fittings. The barb end should be secured with an appropriate hose clamp rated for the system pressure and fluid type. Do not overtighten the swivel nut, as brass threads can be damaged; follow applicable system pressure ratings and relevant fluid power standards such as SAE J514.
