Dixon Valve Coupling 1820404S Hose Male Stem 1/4 Nptf

Product Description

The DIXON VALVE COUPLING 1820404S is a reusable male stem hose fitting designed for 1/4 inch hose ID applications with a 1/4 inch NPTF threaded connection. Constructed from brass, this fitting delivers reliable sealing in threaded fluid or air line assemblies. At 1.86 inches overall length and weighing just 0.1 pounds, it is a compact, field-serviceable component suited for hydraulic, pneumatic, and general-purpose fluid transfer systems. The NPTF thread standard provides a pressure-tight mechanical seal without relying solely on sealant tape. Licensed plumbers, pipefitters, and industrial maintenance technicians commonly specify this type of fitting for reusable hose end assemblies.

This fitting is appropriate for use in residential and light commercial fluid transfer lines where a 1/4 inch inside diameter hose connects to a threaded port. Typical applications include compressed air lines, hydraulic hose assemblies, and general service fluid systems that require periodic hose replacement without discarding the stem. The reusable design allows the stem to be removed, inspected, and reinstalled with a new hose section, reducing material cost on repeat service calls.

Key Features

• Reusable design allows stem to be reinstalled with replacement hose sections
• Brass construction provides corrosion resistance in air and fluid service
• 1/4 inch NPTF thread delivers a pressure-tight mechanical seal
• Compact 1.86 inch overall length suits tight installation spaces
• Threaded connection type for straightforward assembly and removal

Compatibility

Designed as an OEM-style reusable male stem fitting for 1/4 inch inside diameter hose assemblies with standard 1/4 inch NPTF threaded ports.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or qualified maintenance technicians. Depressurize and drain the hose line completely before disassembling or installing any fitting. NPTF threads are designed to seal on the thread form itself, but applying a compatible thread sealant is common practice depending on the service fluid and applicable codes. Inspect the hose end for cuts or deformation before reusing the stem to ensure a leak-free assembly.
