Dixon Valve Coupling 1840404A Female Hose Fitting 1/4 Npsm

Product Description

The DIXON VALVE COUPLING 1840404A is a reusable female hose fitting designed for low-pressure fluid transfer applications in plumbing and industrial service. Built from brass, this fitting accepts a 1/4 inch hose ID and connects via a 1/4 inch NPSM threaded interface. At 2 inches in overall length and weighing 0.1 pounds, it is a compact, field-reusable component suited for technicians who need a reliable threaded connection without single-use limitations. The NPSM thread standard provides a straight mechanical thread engagement, making it appropriate for applications where a non-tapered, pressure-assisted seal is required.

This fitting is used in light commercial and industrial fluid handling lines where 1/4 inch hose assemblies are common. Typical applications include compressed air distribution, water service lines, and general fluid transfer systems. Plumbers and industrial service technicians install this fitting when a reusable, female-threaded hose end is needed for maintenance or frequent hose change-out scenarios. Its brass construction provides good corrosion resistance for use with water, air, and many common non-aggressive fluids.

Key Features

• Reusable design allows hose removal and reinstallation without replacing the fitting
• Brass construction offers corrosion resistance for water and air service
• 1/4 inch NPSM straight thread for secure mechanical engagement
• Compact 2 inch overall length for use in tight installations
• Threaded connection type for tool-assisted, leak-resistant assembly

Compatibility

Designed as an OEM-style reusable female hose fitting for 1/4 inch hose ID applications using the NPSM thread standard in plumbing and industrial fluid transfer systems.

Installation Notes

Installation is performed by licensed plumbers or qualified industrial service technicians. Shut off fluid supply and depressurize the line before disassembling or installing any hose fitting. NPSM threads are straight and require a compatible straight-thread female or male coupling for proper seating. Apply thread sealant or appropriate gasket material per the system requirements and applicable IPC guidelines.
