Asc Engineered Solutions 8700134458 Reducing Coupling

Product Description

The ASC Engineered Solutions 8700134458 is a malleable black iron reducing coupling designed to connect two pipes of different diameters in threaded piping systems. It transitions from a 1-1/4 inch female thread on one end to a 3/4 inch female thread on the other, allowing for diameter reduction without additional fittings. The malleable iron construction provides high tensile strength and resistance to stress in pressurized lines. The black finish helps resist water, air, and steam, making it suitable for above-grade and in-wall mechanical installations. Licensed plumbers and pipefitters install this fitting in new construction and retrofit applications.

This reducing coupling is used in residential and light commercial piping systems carrying water, air, or steam. It is well suited for gas distribution lines, compressed air runs, and hydronic heating systems where a threaded diameter change is required. The National Pipe Thread (NPT) form ensures a tight, pressure-rated seal when assembled with appropriate thread sealant or tape. It is sold individually and is a common stock fitting for service vans and mechanical rooms alike.

Key Features

• Malleable iron construction for high tensile strength in pressurized piping systems
• Transitions 1-1/4 inch female NPT to 3/4 inch female NPT in a single fitting
• Black finish resists water, air, and steam exposure
• National Pipe Thread form provides a tight, reliable seal
• Sold individually for single-fitting replacement or new installation use

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded piping systems using 1-1/4 inch and 3/4 inch pipe sizes.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the supply line before removing or installing any threaded fitting. Apply an approved thread sealant compound or PTFE tape to the male threads before assembly to ensure a leak-free joint. Follow applicable IPC or IFGC code requirements for the fluid or gas being conveyed.
