Mueller Streamline B028650 Bronze Adapter 3/4 X 1/2 in

Product Description

The MUELLER STREAMLINE B028650 is a bronze adapter fitting designed to transition between a 3/4 inch fitting connection and a 1/2 inch female NPT (FNPT) threaded end. This domestic-made adapter is used in plumbing, HVAC, and hydronic piping systems where a sweat or compression fitting side must connect to a female-threaded port. The bronze construction provides corrosion resistance and durability in both potable water and mechanical system applications. Licensed plumbers and HVAC technicians rely on this type of fitting to complete pipe transitions at equipment connections, valves, and distribution manifolds.

This adapter is suited for residential and light commercial plumbing and mechanical installations. It fits applications where a 3/4 inch fitting-end connection must reduce or transition to a 1/2 inch FNPT threaded port. Typical use cases include connecting copper tubing runs to threaded valve bodies, water heater connections, boiler piping, and fixture supply lines. Domestic manufacture supports compliance with Buy American provisions on applicable projects.

Key Features

• 3/4 inch fitting end to 1/2 inch FNPT transition in a single fitting
• Bronze construction resists corrosion in water and mechanical piping systems

Compatibility

Designed as an OEM-style replacement and standard trade fitting for 3/4 inch fitting-by-1/2 inch FNPT adapter applications in residential and commercial plumbing and mechanical systems.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with IPC and local plumbing codes. Shut off and depressurize the water or fluid system before working on any fitting. Apply thread sealant tape or compound to male threads before engaging the FNPT end. Do not overtighten threaded connections, as bronze fittings can crack under excessive torque; hand-tighten then use wrenches for final seating per standard practice.
