Asc Engineered Solutions 8700133906 Reducing Coupling

Product Description

The ASC Engineered Solutions 8700133906 is a malleable black iron reducing coupling designed to connect two pipes of different diameters in threaded piping systems. This fitting transitions from a 3/8-inch female thread to a 1/4-inch female thread, allowing technicians to reduce pipe size within a run without additional adapters. Malleable iron construction delivers high tensile strength suitable for demanding service conditions. The black finish provides resistance to water, air, and steam exposure. Licensed plumbers and pipefitters install this fitting in low-pressure piping systems across residential and light commercial applications.

This reducing coupling is suited for use in water, air, and steam distribution systems where a threaded pipe size reduction is required. It is commonly installed in HVAC piping, compressed air lines, and general plumbing supply runs. The National Pipe Thread (NPT) form on both ends ensures a pressure-tight seal when properly installed with thread sealant or tape. It is sold individually and fits standard 3/8-inch and 1/4-inch NPT threaded fittings and pipe.

Key Features

• 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
• Reduces from 3/8-inch to 1/4-inch female thread in a single fitting
• Suitable for water, air, and low-pressure steam service

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 3/8-inch and 1/4-inch NPT threaded pipe and fittings in malleable iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC or IPC requirements. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant compound or PTFE tape to male threads before assembly. Do not over-tighten, as malleable iron fittings can crack under excessive torque.
