Dixon Valve Coupling 1420612C Brass Barbed Hose Fitting

Product Description

The DIXON VALVE COUPLING 1420612C is a brass male barbed hose fitting designed to connect 3/8 inch ID hose to a 3/4 inch UNF male threaded port. The connection geometry is a hose barb by male 45 degree SAE end, which provides a secure, leak-resistant joint when properly clamped. The 1420612C measures 1.97 inches in overall length and weighs 0.1 pounds. The hex head size of 0.75 inches accommodates standard open-end or combination wrenches for wrench-tight installation. Plumbers, HVAC technicians, and fluid-system installers working with flexible hose assemblies will find this fitting suitable for a range of low- to medium-pressure hydraulic, fuel, and fluid transfer lines.

This fitting is suited for residential and light commercial applications where a 3/8 inch ID flexible hose must transition to a male 3/4 inch UNF threaded component. Typical install scenarios include hydraulic equipment connections, fuel line assemblies, cooling system plumbing, and general fluid transfer systems that use SAE 45 degree fittings. The barbed configuration secures the hose mechanically, and a hose clamp is typically applied over the barb for a pressure-rated joint. The hose outside diameter accommodated is 0.5 inches (1/2 inch fractional).

Key Features

• Brass construction provides corrosion resistance for water, fuel, and hydraulic fluid service
• Hose barb x male 45 degree SAE end connection for secure hose-to-threaded-port transition
• 3/4 inch UNF male thread matches common SAE hydraulic and fluid system ports
• Accepts 3/8 inch ID hose with 1/2 inch outside diameter
• 0.75 inch hex head allows wrench installation without slipping
• Compact 1.97 inch overall length suits tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for fluid transfer systems using 3/8 inch ID flexible hose and 3/4 inch UNF male SAE 45 degree threaded ports.

Installation Notes

Installation is typically performed by licensed plumbers or hydraulic system technicians. Depressurize and drain the fluid system before removing or installing any fittings. Use a properly sized open-end wrench on the hex head to torque the fitting to the port — do not use pipe wrenches or pliers on the hex flats. Secure the hose over the barb with an appropriately rated hose clamp, and inspect the joint for leaks before returning the system to service.
