Dixon Valve Coupling 1820804S Male Stem 1/4 Nptf

Product Description

The DIXON VALVE COUPLING 1820804S is a reusable hose male stem fitting designed for secure, leak-resistant hose-to-pipe connections in fluid transfer applications. It features a 1/4 inch NPTF thread for a dry-seal threaded connection and fits a 1/2 inch hose inner diameter. The reusable design allows the stem to be removed and reinstalled without replacing the entire assembly, making it a practical choice for maintenance-heavy environments. This fitting is installed by plumbers, pipefitters, and industrial fluid-system technicians working on hose assemblies in hydraulic, pneumatic, water, or general-purpose fluid lines.

This male stem fitting is suited for use in residential, commercial, and light industrial settings where hose assemblies require a reliable threaded connection point. It is a common component in plumbing maintenance kits, fluid transfer rigs, and irrigation or pressure-washing setups where 1/2 inch hose ID and 1/4 inch NPTF thread sizing apply. The reusable construction makes it appropriate for field repair and scheduled maintenance scenarios where minimizing component waste and downtime is a priority.

Key Features

• 1/4 inch NPTF dry-seal thread provides a pressure-tight connection without sealant tape on all applications
• Fits 1/2 inch hose inner diameter for a secure, low-profile stem engagement

Compatibility

Designed as an OEM-style replacement or service fitting for hose assemblies requiring a 1/4 inch NPTF male stem with a 1/2 inch hose ID connection.

Installation Notes

Installation should be performed by a qualified plumber or pipefitter familiar with NPTF threaded fittings and hose assembly procedures. Depressurize and drain the hose or line completely before removing or installing any fitting. NPTF threads are designed to seal on the threads themselves, but inspect thread condition before assembly and ensure the stem is fully seated in the hose ID before securing the coupling. Follow applicable IPC and local plumbing code requirements for the specific fluid type and pressure rating of the system.
