Dixon Valve Coupling MSC1856124K Female Swivel Fitting 1/4

Product Description

The DIXON VALVE COUPLING MSC1856124K is a reusable female swivel hose fitting designed for fluid transfer connections in plumbing, industrial, and general-purpose hose assembly applications. The fitting features a 1/4-inch NPSM thread and accepts hose with a 3/8-inch inner diameter and a 3/4-inch outer diameter. The swivel design allows rotation during connection, reducing hose twist and simplifying installation in tight or awkward spaces. The reusable construction means the fitting can be removed and reinstalled without replacing the hose end, making it a practical choice for service and maintenance work.

This fitting is suited for use in low-pressure fluid lines where a National Pipe Straight Mechanical thread is specified. It is commonly installed in compressed air, water, and light hydraulic hose assemblies in residential, commercial, and light industrial settings. Plumbers, pipefitters, and general maintenance technicians are the typical installers. The 1/4-inch NPSM thread mates with corresponding female or male straight-thread ports and does not require thread sealing compound where a captured O-ring or gasket is present, though application conditions should always be verified before installation.

Key Features

• Reusable design allows removal and reinstallation without replacing the hose end
• Female swivel configuration reduces hose twist during make-up
• 1/4-inch NPSM straight mechanical thread for leak-resistant connections
• Fits hose with 3/8-inch ID and 3/4-inch OD
• Lightweight at 0.1 pounds for easy handling in the field

Compatibility

Designed as a reusable OEM-style replacement fitting for hose assemblies requiring a 1/4-inch NPSM female swivel end on 3/8-inch ID, 3/4-inch OD hose.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter following applicable IPC and system-specific pressure guidelines. Depressurize and drain the line fully before disassembling any existing hose end fitting. The swivel nut should be threaded on by hand first, then tightened with a wrench to avoid cross-threading the NPSM connection. Verify hose OD and ID dimensions before assembly to ensure a secure, leak-free crimp or clamp fit.
