Asc Engineered Solutions 311090203 Reducing Coupling 2.5x1.5in

Product Description

The ASC ENGINEERED SOLUTIONS 311090203 is a threaded galvanized malleable iron reducing coupling designed to connect two pipes of different diameters in a threaded piping system. Sized at 2.5 inches by 1.5 inches, this fitting transitions from a larger run to a smaller branch line without welding or special tooling. The galvanized coating provides corrosion resistance for both indoor and outdoor installations. Domestically produced, it meets the durability expectations required in commercial and industrial piping applications. Licensed plumbers and pipefitters are the primary installers of this type of reducing coupling.

This reducing coupling is suited for use in residential and commercial plumbing, fire protection, and general-purpose piping systems where a threaded iron fitting is required. It handles transitions between 2.5-inch and 1.5-inch threaded pipe runs. Typical applications include branch reductions in supply lines, mechanical room piping, and similar threaded iron pipe assemblies where a secure, leak-free reduction in line size is needed.

Key Features

• Malleable iron construction provides strength and impact resistance in threaded piping systems
• Galvanized coating resists corrosion in exposed or damp environments
• Threaded connection type for tool-only installation without welding
• Reducing design transitions from 2.5-inch to 1.5-inch pipe in a single fitting
• Domestically produced for consistent dimensional tolerances

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded malleable iron pipe systems using 2.5-inch by 1.5-inch NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable codes such as the IPC or IFGC where relevant. Depressurize and drain the line completely before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to the male threads before assembly, and tighten to proper engagement using a pipe wrench. Do not over-torque malleable iron fittings, as this can crack the casting.
