Dixon Valve Coupling MSC1836106K Male Hose Fitting 3/8 Nptf

Product Description

The DIXON VALVE COUPLING MSC1836106K is a reusable male hose fitting designed for threaded hydraulic and fluid-transfer applications requiring a reliable, leak-resistant connection. Constructed from brass, this fitting accepts a 3/8-inch hose inner diameter and a 5/8-inch hose outer diameter, and threads into female NPTF ports using a standard 3/8-inch thread. The NPTF thread form creates a dry-seal connection by crushing thread flanks together, reducing reliance on sealant tape. Its reusable design allows the fitting to be removed and reinstalled without damaging the hose end, making it a practical choice for maintenance-heavy systems. Installation is handled by plumbers, HVAC technicians, and industrial fluid-system mechanics.

This fitting is suited for low- to medium-pressure fluid transfer lines in residential, commercial, and light industrial settings. Typical applications include compressed air lines, water supply hoses, hydraulic service lines, and general-purpose hose assemblies where a threaded male NPTF termination is required. The brass construction offers corrosion resistance in water, air, and a broad range of compatible fluids. At 0.1 pounds, the fitting is lightweight and easy to handle during installation in confined equipment spaces.

Installation Notes

This fitting is installed by licensed plumbers or qualified mechanical technicians. Depressurize and drain the system completely before removing or installing any hose fittings. Although NPTF threads are designed as dry-seal connections, consult applicable IPC or system manufacturer guidelines regarding the use of thread sealant for the specific fluid service. Inspect the hose end and fitting threads for damage before assembly to ensure a proper seal.
