The ASC Engineered Solutions 8700135158 is a reducing galvanized coupling designed for threaded pipe systems requiring a transition from a larger to a smaller female pipe thread connection. Built from malleable iron, this fitting offers high tensile strength suited to demanding plumbing and mechanical piping applications. The galvanized finish provides rust resistance for long service life in typical indoor and light commercial installations. It is sized at 1/2 inch FPT on the larger end and 1/4 inch FPT on the smaller end, making it a standard choice for reducing connections in threaded iron pipe assemblies.
This reducing coupling is used in residential and light commercial plumbing, gas distribution, and mechanical piping systems where a threaded iron pipe size reduction is required. It is well suited for connecting supply lines, branch connections, and instrument taps where a 1/2 inch to 1/4 inch FPT reduction is specified. Licensed plumbers and pipefitters are the typical installers in these applications.
Designed as an OEM-style replacement and standard fitting for threaded malleable iron pipe systems using 1/2 inch and 1/4 inch female pipe thread connections.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements where gas service is involved. Shut off the supply line and relieve system pressure before disassembling any threaded connections. Apply appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-tighten, as malleable iron fittings can crack if excessive torque is applied with power tools.
