Dixon Valve Coupling 1820608S Male Stem 1/2 in Nptf

Product Description

The DIXON VALVE COUPLING 1820608S is a reusable hose male stem fitting designed for use in fluid transfer and hose assembly applications. Built from brass, this male stem accepts a 3/8-inch hose ID and connects via a 1/2-inch NPTF threaded end, providing a pressure-tight seal without the need for a sealant in many applications. At 2.17 inches in overall length and weighing 0.1 pounds, it is a compact, field-serviceable component. Licensed tradespeople and experienced technicians install this type of fitting when assembling or repairing hydraulic, pneumatic, or general-purpose fluid hose lines where a reusable connection is preferred over a crimp-style termination.

This male stem fitting is suited for use in industrial, commercial, and trade service environments where hose assemblies must be built or replaced in the field. It is commonly installed in plumbing, HVAC, and general fluid-handling systems that require a reliable threaded hose end. The NPTF thread standard ensures compatibility with standard tapered female pipe thread ports. Applications include water, air, and compatible fluid lines where a 3/8-inch hose ID and 1/2-inch NPTF male thread are specified.

Key Features

• Reusable design allows disassembly and reinstallation without replacing the fitting
• Brass construction provides corrosion resistance for water and general fluid service
• 1/2-inch NPTF thread delivers a pressure-tight connection at the port end
• Accepts 3/8-inch hose ID for compatibility with standard hose stock
• Compact 2.17-inch overall length suits tight installation spaces
• Threaded connection type supports tool-assisted installation and removal

Compatibility

Designed for use with 3/8-inch hose ID assemblies requiring a 1/2-inch NPTF male stem termination. Compatible with hose lines in systems that specify NPTF tapered thread fittings in brass.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or qualified mechanical technicians. Depressurize and drain the hose assembly completely before disassembly or fitting installation. Use appropriate hand tools to seat the NPTF thread firmly without overtightening, which can crack brass fittings. Verify thread engagement and check for leaks after returning the system to service pressure.
