Dixon Valve Coupling 1840604A Reusable Hose Female Fitting

Product Description

The DIXON VALVE COUPLING 1840604A is a reusable female hose fitting designed for threaded hose-end connections in fluid transfer applications. Constructed from brass, this fitting features a 1/4 inch NPSM (National Pipe Straight Mechanical) thread standard and accepts a 3/8 inch hose ID. At 2.12 inches in overall length and weighing just 0.1 pounds, it is a compact, durable component suited for low-to-medium pressure hose assemblies. The reusable design allows the fitting to be installed and removed without destroying the hose end, reducing material waste during maintenance or hose replacement. Plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this type of fitting.

This fitting is commonly used in plumbing, fluid handling, and general industrial hose assemblies where a reliable threaded female end connection is required. The 1/4 inch NPSM thread is a straight mechanical thread, making it appropriate for applications where a swivel or mechanical seal joint is needed rather than a tapered pipe thread. Typical installations include water lines, light hydraulic service hose ends, and similar low-pressure fluid transfer systems in both commercial and light industrial environments.

Key Features

• Reusable design allows removal and reinstallation without hose damage
• Brass construction provides corrosion resistance in water and general fluid service
• 1/4 inch NPSM straight mechanical thread for secure, non-tapered connection
• Fits 3/8 inch hose ID for common hose sizes in plumbing and fluid transfer
• Compact 2.12 inch overall length suits tight installation spaces
• Threaded connection type for straightforward assembly with standard tools

Compatibility

Designed as an OEM-style replacement or service fitting for hose assemblies requiring a 1/4 inch NPSM female threaded end connection on 3/8 inch ID hose.

Installation Notes

Installation is typically performed by a licensed plumber or qualified pipefitter following applicable IPC or facility fluid system guidelines. Shut off and depressurize the fluid system completely before disassembling any hose end fittings. Use appropriate hand tools such as a wrench to seat the fitting securely without overtightening, which can distort the brass threads. Inspect the hose end for cuts or abrasion before installing a reusable fitting to ensure a proper seal.
