The ASC Engineered Solutions 8700135455 is a reducing galvanized coupling designed to connect female pipe thread (FPT) fittings between 1-inch and 1/2-inch pipe sizes. Constructed from malleable iron, this fitting delivers high tensile strength suited to demanding piping systems. The galvanized finish provides a protective zinc coating that resists rust and corrosion in wet or exposed environments. This fitting is sold individually and is intended for installation by licensed plumbers and pipefitters working on residential or commercial piping systems.
This reducing coupling is used in threaded pipe assemblies where a transition from a larger 1-inch line to a smaller 1/2-inch branch is required. It is a common component in water supply, hydronic heating, and general-purpose piping systems. The FPT configuration on both ends allows it to thread directly onto male-threaded pipe or fittings without additional adapters.
Designed as an OEM-style replacement or new-installation component for standard threaded malleable iron pipe systems using 1-inch and 1/2-inch NPT-compatible connections.
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 water or fluid supply before beginning any work on the piping system. Apply appropriate thread sealant or PTFE tape to male threads before assembly, and tighten fittings with a pipe wrench to a snug, leak-free connection without overtightening malleable iron threads.
