Dixon Valve Coupling 1840606A Reusable Hose Female Stem

Product Description

The DIXON VALVE COUPLING 1840606A is a reusable female stem hose fitting designed for secure, threaded hose connections in fluid transfer applications. Machined from brass, this fitting accepts a 3/8 inch hose inner diameter and uses a 3/8 inch NPSM threaded connection for reliable sealing without the need for sealant tape on every makeup. At 2.18 inches in overall length, it is a compact fitting suited for tight plumbing and hose assembly runs. The reusable design allows field disassembly and reassembly without replacing the fitting, making it a practical choice for maintenance-heavy environments. Plumbers, industrial pipefitters, and fluid-handling technicians are the typical installers.

This female stem fitting is used in low-pressure fluid transfer lines where a reusable, field-serviceable connection is preferred over a crimp-style permanent termination. Common applications include water supply hoses, compressed air hose assemblies, and general industrial fluid lines where 3/8 inch hose ID is standard. The NPSM thread standard provides a straight mechanical thread engagement, distinguishing it from tapered NPT fittings in assemblies that require repeated breakaway and remake cycles.

Key Features

• Reusable design allows disassembly and field reassembly without replacing hardware
• Brass construction provides corrosion resistance in water and air service
• 3/8 inch NPSM straight threaded connection for controlled thread engagement
• Accepts 3/8 inch hose inner diameter for direct hose coupling
• Compact 2.18 inch overall length fits in space-constrained hose assemblies

Compatibility

Designed as an OEM-style reusable female stem fitting for 3/8 inch inner diameter hose assemblies using NPSM straight thread connections in plumbing and industrial fluid transfer applications.

Installation Notes

Installation is performed by qualified plumbers or pipefitters familiar with hose assembly and threaded brass fittings. Depressurize and drain the hose line completely before disassembling any fitting. NPSM is a straight thread standard and does not rely on thread taper for sealing, so verify that mating components also carry NPSM designation before assembly. Avoid over-tightening brass fittings, as the material is susceptible to thread damage under excessive torque.
