Dixon Valve Coupling MSC1838146K Reusable Male Hose Fitting

Product Description

The DIXON VALVE COUPLING MSC1838146K is a reusable male hose fitting designed for reliable fluid transfer connections in plumbing, hydraulic, and industrial hose assemblies. Constructed from brass, this fitting features a 3/8 inch NPTF threaded end and is sized for hose with a 1/2 inch inner diameter and a 7/8 inch outer diameter. The NPTF thread standard provides a pressure-tight mechanical seal without requiring additional sealant tape in many applications. Weighing 0.1 pounds, this is a compact, single-piece fitting suited for licensed plumbers and fluid system technicians working on reusable hose end assemblies.

This fitting is appropriate for use in residential and light commercial fluid transfer applications where a reusable, field-serviceable hose connection is preferred over a crimp-style end. It is commonly installed on rubber or reinforced hose assemblies used in hydraulic lines, water supply runs, and general-purpose plumbing. The reusable design allows the fitting to be removed and reinstalled when hose replacement or system reconfiguration is required, reducing material waste on repeat service calls.

Key Features

• Brass construction provides corrosion resistance and durability in wet and pressurized environments
• 3/8 inch NPTF thread delivers a pressure-tight seal through thread interference fit
• Reusable design supports field disassembly and reassembly without replacing the fitting
• Fits hose with 1/2 inch ID and 7/8 inch OD for a secure mechanical grip
• Threaded connection type for straightforward installation with standard hand tools
• Compact and lightweight at 0.1 pounds, easy to carry as a service spare

Compatibility

Designed as an OEM-style reusable male hose fitting for rubber or reinforced hose assemblies with a 1/2 inch inner diameter and 7/8 inch outer diameter, using a 3/8 inch NPTF threaded port.

Installation Notes

Installation should be performed by a licensed plumber or qualified fluid systems technician. Shut off all fluid supply and relieve system pressure completely before disassembling any hose end or fitting. NPTF threads are designed to seal through thread interference, but verify the mating port thread standard before installation to avoid cross-threading or leaks. Follow applicable IPC and local plumbing code requirements when integrating into potable water or pressurized fluid systems.
