Asc 8700133856 Black Iron Reducing Coupling 1/4x1/8 in

Product Description

The ASC Engineered Solutions 8700133856 is a malleable black iron reducing coupling designed to connect a 1/4-inch pipe to a 1/8-inch pipe in threaded piping systems. Malleable iron construction delivers high tensile strength, making this fitting suitable for demanding service environments. National Pipe Thread (NPT) tapered threads form a tight, reliable seal without relying solely on thread sealant. The black finish provides resistance to water, air, and steam, extending service life in typical piping installations. Plumbers and pipefitters install this coupling wherever a threaded pipe size reduction is required in a straight run.

This reducing coupling is suited for residential and light commercial plumbing, gas distribution, steam, and compressed-air piping systems where a 1/4-inch to 1/8-inch inline reduction is needed. It is commonly installed in supply lines, manifold assemblies, and instrument connection points. The compact size makes it practical in tight spaces and panel installations where inline reducers are preferred over bushings.

Key Features

• Malleable iron construction for high tensile strength and durability
• National Pipe Thread (NPT) tapered threads for a tight, reliable seal
• Black finish resists water, air, and steam exposure
• 1/4-inch female inlet to 1/8-inch female outlet inline reduction
• Sold individually — single-unit packaging

Compatibility

Designed as an OEM-style threaded fitting replacement for malleable black iron piping systems using NPT-threaded connections in plumbing, gas, steam, and compressed-air applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code (IPC), or the International Fuel Gas Code (IFGC) as appropriate for the service medium. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Hand-tighten first, then use a pipe wrench to achieve a firm, leak-free connection without overtightening, which can crack malleable iron fittings.
