Asc 8700134607 Black Iron Reducing Coupling 1-1/2 X 1 in

Product Description

The ASC Engineered Solutions 8700134607 is a malleable black iron reducing coupling designed to connect pipes of two different sizes in threaded piping systems. It transitions from a 1-1/2 inch female thread on one end to a 1-inch female thread on the other, allowing plumbers and pipefitters to reduce pipe diameter inline without additional fittings. The malleable iron construction delivers high tensile strength, and the black finish provides resistance to water, air, and steam. National Pipe Thread (NPT) form on both ends ensures a tight, reliable seal in standard threaded installations. This coupling ships as an individual unit and weighs 0.9 pounds.

This reducing coupling is suited for residential and commercial piping applications where a threaded iron pipe system requires an inline diameter change. Typical installation scenarios include water supply lines, air distribution, steam systems, and general industrial piping. It is well-suited for mechanical rooms, boiler connections, and utility piping where NPT fittings are standard practice. Licensed plumbers and pipefitters are the primary installers for this type of fitting.

Key Features

• Reduces from 1-1/2 inch to 1 inch female NPT thread in a single fitting
• Malleable iron construction for high tensile strength and durability
• Black finish resists water, air, and steam corrosion
• National Pipe Thread (NPT) form on both ends for a tight, leak-resistant seal
• Sold individually — no minimum order beyond one unit

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded iron pipe systems. Compatible with 1-1/2 inch and 1 inch Schedule 40 black iron or galvanized pipe with NPT threads.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly to ensure a leak-free joint. Do not overtighten — hand-tighten first, then use a pipe wrench for final make-up to avoid cracking the fitting.
