Dixon Valve Coupling MSC1836118K Male Hose Fitting 1/2 Nptf

Product Description

The DIXON VALVE COUPLING MSC1836118K is a reusable male hose fitting designed for secure, leak-resistant connections in fluid transfer applications. It features a 1/2 inch NPTF thread and accepts hose with a 3/8 inch inner diameter and an 11/16 inch outer diameter. The NPTF thread standard provides a dry-seal connection, relying on thread-form interference rather than a separate sealant or washer to prevent leakage under pressure. At 0.1 pounds, this fitting is compact and lightweight, making it a practical replacement or spare for plumbing, pneumatic, or hydraulic hose assemblies. It is installed by plumbers, pipefitters, and industrial maintenance technicians working with compatible hose assemblies.

This fitting is suited for applications where hose assemblies require field-replaceable end fittings without cutting or crimping equipment. The reusable design allows the fitting to be removed from a worn or damaged hose section and reinstalled on a new hose, reducing replacement cost on service calls. Typical use cases include fluid transfer lines in light industrial, commercial plumbing, and general-purpose pneumatic systems where 3/8 inch ID hose and NPTF threaded ports are specified.

Key Features

• NPTF dry-seal thread standard for leak-resistant connections without additional sealant
• Reusable design allows disassembly and reinstallation on replacement hose
• Accepts 3/8 inch hose ID and 11/16 inch hose OD for a secure mechanical grip
• 1/2 inch thread size compatible with standard NPTF ported equipment and manifolds
• Lightweight at 0.1 pounds for easy handling in tight installation spaces

Compatibility

Designed as an OEM-style replacement male hose fitting for systems using 3/8 inch inner diameter hose with a 11/16 inch outer diameter and a 1/2 inch NPTF threaded port connection.

Installation Notes

This fitting is typically installed by licensed plumbers, pipefitters, or qualified maintenance technicians. Depressurize and drain the hose assembly fully before disassembly or installation. NPTF fittings rely on thread interference for sealing, but consult applicable system requirements to confirm whether thread sealant is appropriate for the service fluid. Follow IPC and system manufacturer guidelines for torque and pressure ratings of hose assemblies in service.
