Asc Engineered Solutions 810091207 Reducing Coupling 3x1.5 in

Product Description

The ASC Engineered Solutions 810091207 is a black malleable iron reducing coupling designed for joining threaded pipe sections of two different diameters in a single inline connection. This fitting transitions from a 3-inch female thread on one end to a 1-1/2-inch female thread on the other, making it a workhorse component in black iron piping systems used for gas distribution, compressed air, and industrial fluid transport. The black coating provides a consistent surface finish suited to non-corrosive environments. Plumbers, pipefitters, and mechanical contractors install this fitting in both commercial and light industrial applications.

This reducing coupling is used in systems requiring a direct inline diameter reduction without an offset. Common install scenarios include gas supply mains stepping down to branch lines, compressed air headers feeding smaller distribution drops, and general-purpose pipe assemblies where malleable iron fittings are specified. Its threaded connection style makes it compatible with standard NPT pipe threads found throughout residential and commercial mechanical systems.

Key Features

• Inline reducing connection: 3 inches on the large end, 1-1/2 inches on the small end
• Malleable iron construction provides strength and resistance to impact compared to cast iron
• Black coating finish suitable for gas, air, and non-potable fluid piping
• Threaded NPT-style connection for standard pipe assembly
• Weighs 2.66 pounds, indicating a robust, full-weight fitting suitable for trade use

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded black iron pipe systems requiring a 3-inch by 1-1/2-inch inline reducing coupling in malleable iron construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes, including IFGC and ASME B31 standards where gas or pressure piping is involved. Shut off all gas or system pressure and verify zero pressure before disassembling or assembling any threaded connection. Apply an approved pipe thread sealant or PTFE tape to all male threads before assembly. Do not over-torque threaded connections in malleable iron fittings, as this can crack the fitting body.
