The ASC Engineered Solutions 8700135257 is a reducing galvanized coupling designed to connect female pipe thread (FPT) fittings where a 3/4-inch line steps down to a 1/2-inch line. Constructed from malleable iron, this coupling delivers high tensile strength suited for demanding pipe system applications. The galvanized finish provides corrosion resistance, extending service life in environments where rust is a concern. It is sold as an individual unit and is a standard component in low-pressure piping assemblies installed by licensed plumbers and pipefitters.
This reducing coupling is used in residential and light commercial plumbing and gas distribution systems where pipe diameter transitions are required. It is appropriate for use in threaded pipe assemblies following standard FPT connection practices. The fitting suits applications in water supply, low-pressure gas lines, and general-purpose pipe installations where malleable iron fittings are specified.
Designed as an OEM-style replacement or new-installation fitting for standard threaded malleable iron pipe systems using FPT connections in residential and commercial plumbing and gas piping assemblies.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the pipe system fully before disassembly or fitting installation. Apply appropriate thread sealant or PTFE tape to all male threads before making up the joint. Do not over-tighten threaded connections on malleable iron fittings, as this can crack the fitting body.
