The ASC Engineered Solutions 8700135851 is a 2-inch by 1-1/2-inch female pipe thread (FPT) reducing galvanized coupling manufactured by Anvil. This malleable iron fitting connects two threaded pipe sections of different diameters in a single inline transition, reducing from a 2-inch FPT inlet to a 1-1/2-inch FPT outlet. The galvanized finish provides corrosion resistance for use in wet or humid environments. Malleable iron construction delivers high tensile strength suited to demanding mechanical and plumbing installations. Licensed plumbers and pipefitters install this type of fitting in commercial and residential piping systems where pipe size reduction is required at a threaded connection point.
This reducing coupling is used in threaded pipe assemblies for water supply, gas distribution, and general mechanical piping applications. The FPT threads on both ends accept standard male-threaded pipe ends, making this a straightforward inline reducer for new construction or retrofit work. The galvanized coating makes it appropriate for above-ground and exposed piping runs where corrosion resistance is a priority. It is sold individually and is compatible with standard NPT-threaded iron or steel pipe.
Designed as an OEM-style replacement or new-installation fitting for standard NPT-threaded malleable iron pipe systems requiring an inline reduction from 2-inch to 1-1/2-inch pipe size.
Installation is performed by a licensed plumber or pipefitter following applicable IPC and IFGC guidelines for threaded iron pipe assemblies. Shut off the water or gas supply and depressurize the line before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to all male threads before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.
