Asc Engineered Solutions 8700134409 Reducing Coupling

Product Description

The ASC Engineered Solutions 8700134409 is a malleable black iron reducing coupling designed to connect pipe runs where the line size steps down from 1-1/4 inches to 1 inch. Malleable iron construction provides high tensile strength and durability in demanding piping systems. National Pipe Taper (NPT) threads deliver a tight, reliable seal on both ends. The black finish adds resistance to water, air, and steam exposure, making this fitting suitable for a range of mechanical piping applications. Plumbers and pipefitters install this type of coupling wherever a threaded pipe reduction is required in a straight run.

This reducing coupling is used in residential and light commercial piping systems carrying water, air, or steam. It is a standard threaded fitting appropriate for black iron pipe distribution systems, including gas piping, compressed air lines, and steam heating distribution. The 1-1/4 inch by 1 inch reduction size addresses one of the most common step-down transitions in mechanical system piping. Installation is performed by licensed plumbers or pipefitters following applicable code requirements.

Key Features

• Malleable iron construction for high tensile strength and impact resistance
• NPT threads on both ends for a tight, leak-resistant seal
• Black finish resists water, air, and steam
• 1-1/4 inch female inlet reduces to 1 inch female outlet
• Sold individually as a single unit

Compatibility

Designed as an OEM-style replacement and standard fitting for threaded black iron pipe systems using National Pipe Taper threads in 1-1/4 inch and 1 inch nominal pipe sizes.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters. Shut off and depressurize the piping system completely before removing any existing fittings or threading on this coupling. Apply appropriate thread sealant or PTFE tape to NPT threads before assembly to ensure a leak-free joint. Follow all applicable local codes, including IPC and IFGC provisions, for the specific service type.
