Dixon Valve Coupling DV-00198 Barbed Hose Fitting Adapter

Product Description

The DIXON VALVE COUPLING DV-00198 is a brass barbed hose fitting adapter designed to connect flexible hose to threaded ports in fluid transfer systems. It features a 1/8 inch male NPTF thread on one end and a 1/4 inch ID barb on the other, allowing a transition from a threaded fitting to barbed hose in a single component. At 1.57 inches in overall length, it is a compact fitting suited for tight plumbing runs. The brass construction provides corrosion resistance appropriate for water, air, and many common fluid applications. Plumbers, HVAC technicians, and general mechanical contractors install this type of fitting in low-pressure line assemblies.

This adapter is used in residential and light commercial plumbing, HVAC, and pneumatic systems where a threaded port must mate with a barbed hose connection. The 1/8 inch MNPTF thread is a common port size found on solenoid valves, manifolds, pressure gauges, and similar equipment. The 1/4 inch ID barb accepts standard flexible tubing of the corresponding inside diameter. It is sold in a package quantity of five units, making it practical for service trucks and shop stock.

Compatibility

Designed as a standard barbed hose fitting adapter for use with 1/4 inch ID flexible hose and equipment with 1/8 inch MNPTF threaded ports in low-pressure plumbing, HVAC, and pneumatic applications.

Installation Notes

This fitting is installed by plumbers and HVAC technicians working on low-pressure fluid or air lines. Shut off the fluid supply and depressurize the line before installation. Apply thread sealant appropriate for the fluid type to the MNPTF threads and hand-tighten before using a wrench. Secure the hose over the barb with a clamp rated for the application pressure and fluid type.
