Dixon Valve Coupling MSC1834104K Male Hose Fitting Nptf

Product Description

The DIXON VALVE COUPLING MSC1834104K is a reusable male hose fitting machined from brass for use in fluid transfer and compressed air plumbing applications. It features a 1/4 inch NPTF threaded connection and fits hose with a 0.25 inch inner diameter and 0.625 inch outer diameter. The NPTF thread form creates a dry-seal connection that resists leakage without relying solely on thread sealant. The reusable design allows the fitting to be removed and reinstalled on new hose sections, reducing material waste during maintenance. Plumbers, pipefitters, and industrial mechanics install this type of fitting in low-pressure fluid and air lines across residential, commercial, and light industrial settings.

This fitting is suited for applications where a threaded male end must transition from a soft hose to a rigid pipe or manifold port. Typical uses include compressed air distribution lines, hydraulic fluid transfer hose assemblies, and general-purpose water supply connections. The brass construction resists corrosion in wet or humid environments, making it appropriate for both indoor mechanical rooms and outdoor service locations. Installation requires no special tooling beyond a standard wrench and compatible hose clamp or ferrule depending on assembly method.

Key Features

• Brass construction provides corrosion resistance in wet and humid service environments
• 1/4 inch NPTF dry-seal thread standard minimizes risk of thread-joint leakage
• Reusable design allows removal and reinstallation on replacement hose sections
• Fits 0.25 inch ID x 0.625 inch OD hose for a secure mechanical grip
• Threaded connection type is compatible with standard pipe fittings and manifold ports

Compatibility

Designed as a standard reusable male hose fitting for use with hose having a 0.25 inch inner diameter and 0.625 inch outer diameter, threaded to 1/4 inch NPTF for connection to compatible NPTF or NPT female ports.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and facility-specific fluid handling codes. Depressurize and drain the line completely before removing or installing any hose fitting. Inspect the hose end for cuts, abrasion, or deformation before threading the fitting onto the hose. Apply thread sealant tape or compound to the male threads only when connecting to NPT female ports, as NPTF joints may not require it depending on system pressure and media.
