Dixon Valve Coupling DV-00201 Barbed Hose Adapter Brass

Product Description

The DIXON VALVE COUPLING DV-00201 is a brass barbed hose fitting adapter designed to connect a 1/4 inch ID hose to a 1/2 inch male NPTF threaded port. The barbed end provides a secure mechanical grip on flexible hose, while the MNPTF thread seals against tapered female pipe threads without requiring additional sealant tape in many applications. At 1.97 inches overall length and weighing under 0.1 pounds, it is a compact, single-piece fitting suited for fluid transfer lines in plumbing, HVAC auxiliary drainage, and general industrial hose assemblies. Plumbers, pipefitters, and HVAC technicians install this fitting where a transition between a threaded pipe connection and a small-bore flexible hose is required.

This adapter is appropriate for low-pressure fluid transfer applications that call for a 1/4 inch ID hose terminating at a 1/2 inch MNPTF port. Typical uses include condensate drain lines, equipment cooling circuits, chemical feed lines, and similar service. The brass construction provides corrosion resistance suitable for water, light oils, and many common process fluids. This fitting is sold in a package quantity of 5, making it practical for service trucks and shop stock where multiple installations are anticipated.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Shut off fluid supply and relieve system pressure before removing or installing any hose fitting. MNPTF threads are tapered and rely on thread interference for sealing; inspect threads for damage before assembly and apply thread sealant per the system fluid compatibility requirements. Secure the hose to the barbed end with an appropriately sized hose clamp to prevent blowoff under pressure.
