The Grainger Approved Reducer is a 3/4" x 1/2" NPT brass reducer bushing that allows you to connect pipes or fittings of different sizes. It is made of brass for durability and has NPT threads on both ends to create a tight seal. This reducer bushing enables you to transition from a larger 3/4" pipe thread to a smaller 1/2" pipe thread. It can handle pressures up to 300 PSI and temperatures up to 250°F. The dimensions are 1-1/4" length x 1" width. This reducer fitting is ideal for reducing pipe sizes in plumbing, HVAC, hydraulic, instrumentation, industrial, and oil & gas applications.
