The BRASSCRAFT 48-8-6wn is a brass flared reducing adapter designed to transition between a 1/2 inch OD flare connection on one end and a 3/8 inch male fitting on the other. This adapter is used in fluid and gas piping systems where two different flare sizes must be joined without leaks or pressure loss. Constructed entirely from brass, it offers reliable corrosion resistance and durability in both water and fuel gas service. Licensed plumbers and mechanical contractors install this fitting in residential and light commercial applications where flare-type connections are specified by code or equipment requirements.
This reducing adapter is suited for water supply lines, fuel gas distribution systems, and mechanical equipment hookups that require a size transition between standard flare fittings. Its compact profile, measuring 1.95 inches in height and 0.8 inches in width, allows installation in tight spaces typical of appliance connections and supply rough-in work. The OD flare by male end style makes it compatible with standard compression-type flare systems used throughout plumbing and HVAC service work.
Designed as an OEM-style replacement or service fitting for residential and light commercial plumbing and gas systems using standard OD flare compression connections.
Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with applicable local codes and the International Plumbing Code or International Fuel Gas Code. Shut off the water supply or close the gas valve and relieve system pressure completely before removing or installing any flare fitting. Inspect flare seats on both mating connections for damage or debris before assembly. Do not over-tighten flare fittings, as deformation of the flare seat can cause leaks.
