Midland Industries 28185 Brass Reducing Coupling Nptf

Product Description

The MIDLAND INDUSTRIES 28185 is a brass reducing coupling designed to connect two female NPTF threaded pipe ends of different sizes. One end accepts 1/2-inch female NPTF (1/2-14 thread) and the other accepts 3/8-inch female NPTF (3/8-18 thread), making it a practical solution for reducing down between pipe runs without additional adapters. The coupling is rated to 1200 psi and handles temperatures from -65 to 250 degrees F. The 1.06-inch hex profile allows for secure wrench engagement during installation. Brass construction provides corrosion resistance and durability across a wide range of fluid and gas service applications.

This reducing coupling is suited for residential and light commercial plumbing, HVAC, and industrial piping systems where a transition between 1/2-inch and 3/8-inch female threaded connections is required. It is compatible with brass, bronze, copper, steel, aluminum, and iron pipe. Plumbers, pipefitters, and HVAC technicians commonly use this fitting in gas, air, oil, and water service lines within the rated pressure and temperature limits.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter. Shut off and depressurize the line before threading in the coupling. Apply an appropriate thread sealant or PTFE tape to the male threaded pipe ends before engagement. Use a wrench on the hex flats only - do not grip the body of the fitting - and tighten to a snug, leak-free fit without over-torquing brass threads.
