Dixon Valve Coupling MSC1834086K Male Hose Fitting 3/8 Nptf

Product Description

The DIXON VALVE COUPLING MSC1834086K is a reusable male hose fitting machined from brass and designed for secure, leak-resistant connections in fluid transfer applications. It carries a 3/8 inch NPTF (National Pipe Taper Fuel) thread and accepts hose with a 1/4 inch inside diameter and a 1/2 inch outside diameter. The NPTF thread form creates a pressure-tight mechanical seal without requiring a separate thread sealant, though pipe thread sealant or PTFE tape is commonly applied in the field. This fitting is intended for reuse across multiple hose assemblies, making it a cost-effective option for maintenance and repair work in plumbing, hydraulic, pneumatic, and industrial fluid-handling systems. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical end users.

This fitting is suited for residential and light commercial applications where a reliable threaded male connection is needed between a hose assembly and a female-threaded port or valve. Its brass construction makes it compatible with water, air, and a range of non-corrosive fluid media. The reusable design allows the fitting to be removed and reinstalled on replacement hose without discarding the fitting body, which is useful in maintenance-heavy environments where hose assemblies are serviced regularly.

Key Features

• 3/8 inch NPTF male thread for a pressure-tight mechanical seal
• Accepts 1/4 inch hose ID and 1/2 inch hose OD
• Brass construction resists corrosion in water and air service
• Reusable design reduces replacement cost during routine hose maintenance
• Threaded connection type for straightforward installation with standard hand tools

Compatibility

Designed as an OEM-style reusable male hose fitting for use with hose assemblies requiring a 3/8 inch NPTF male threaded end and a hose with 1/4 inch inside diameter and 1/2 inch outside diameter.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Shut off and depressurize the system completely before removing or installing any hose fitting. Apply PTFE tape or an appropriate pipe thread sealant to the NPTF threads before assembly to ensure a leak-free connection. Do not overtighten; thread engagement should be checked against applicable standards such as IPC or ASME B1.20.3 for NPTF fittings.
