Asc Engineered Solutions 810091405 Malleable Iron Coupling

Product Description

The ASC Engineered Solutions 810091405 is a black malleable iron reducing coupling designed for joining threaded pipe of two different sizes in a single inline connection. Sized at 3 inches by 1-1/4 inches, this reducing coupling connects a larger-diameter pipe run to a smaller-diameter branch or transition point. The black coating provides corrosion resistance suitable for standard piping service. Malleable iron construction delivers the strength and ductility required for threaded mechanical joints in gas, air, and general industrial piping systems. The part weighs 2.55 pounds and is sourced as an import fitting.

This reducing coupling is used in residential and commercial piping installations where a diameter reduction is needed inline. Common applications include gas distribution piping, compressed air lines, and industrial process piping. It is installed by licensed plumbers, pipefitters, and mechanical contractors working with threaded iron pipe systems. The black finish makes it a standard choice for gas line service where bare or galvanized fittings are not specified.

Key Features

• Malleable iron construction for strength and resistance to mechanical stress at threaded joints
• Black coating suitable for gas piping and general industrial service
• Reduces from 3 inches to 1-1/4 inches in a single inline fitting
• Threaded connection type for standard NPT pipe assembly
• Item weight of 2.55 pounds indicating full-weight commercial-grade casting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded malleable iron pipe systems requiring an inline reduction from 3-inch to 1-1/4-inch pipe diameter.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including IFGC requirements when used on gas lines. Shut off and depressurize the pipe system completely before removing any existing fittings or making new connections. Apply an approved thread sealant or PTFE tape rated for the intended service medium before assembly. Do not over-tighten threaded joints; follow standard torque practice for malleable iron to avoid cracking the fitting.
