The ASC Engineered Solutions 8700135109 is a reducing galvanized coupling designed for connecting pipes of two different diameters in threaded piping systems. Manufactured from malleable iron with a galvanized finish, this fitting delivers high tensile strength and corrosion resistance in a compact form. It transitions from a 1/2 inch female pipe thread (FPT) to a 3/8 inch FPT connection. Weighing 0.184 pounds, it is a standard unit-quantity fitting suited for plumbing, mechanical, and light industrial piping applications where a secure, rust-resistant threaded connection is required.
This reducing coupling is used in residential and commercial piping systems where a threaded reduction between pipe sizes is needed. It is appropriate for water supply lines, gas distribution piping, and general mechanical systems that require malleable iron fittings. Licensed plumbers and pipefitters typically install this fitting during rough-in work or repairs involving galvanized pipe assemblies.
Designed as an OEM-style replacement or new-install fitting for standard threaded galvanized pipe systems using 1/2 inch and 3/8 inch female pipe thread connections.
Installation of this fitting should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes such as the IPC. Shut off and depressurize the pipe system completely before removing or installing any fittings. Apply an appropriate pipe thread sealant or PTFE tape to all male threads before assembly. Do not overtighten, as malleable iron fittings can crack under excessive torque from power tools.
