Asc Engineered Solutions 300153004 Eccentric Reducer

Product Description

The ASC ENGINEERED SOLUTIONS 300153004 is a black cast iron eccentric reducer designed for threaded pipe systems where offset flow alignment is required. Unlike concentric reducers, the eccentric design keeps one side of the fitting flat, allowing the pipe centerline to shift during a size transition. This characteristic is critical in horizontal drainage and pump suction piping where maintaining a consistent invert elevation prevents air pockets and improves flow. The fitting transitions from a 1-1/4 inch connection to a 1 inch connection and weighs 0.91 pounds. Licensed plumbers and pipefitters working on commercial or industrial piping installations are the primary installers.

This eccentric reducer is suited for horizontal piping runs where venting and drainage characteristics matter, such as pump suction lines and low-pressure piping systems. The black cast iron construction and coating are appropriate for above-grade plumbing, gas distribution systems, and general industrial piping applications. Its domestic manufacture makes it a fit for projects that specify American-made components in their procurement requirements.

Key Features

• Eccentric geometry keeps one face flat, preventing air pocket formation in horizontal runs
• Cast iron construction provides durability in industrial and commercial piping environments
• Black coating suited for gas and above-grade plumbing piping systems
• 1-1/4 inch to 1 inch size transition in a single compact fitting
• Domestically manufactured

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard threaded cast iron pipe systems requiring a 1-1/4 inch to 1 inch eccentric reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes such as the IPC or local authority having jurisdiction. Shut off and depressurize the piping system completely before removing any existing fittings or making new connections. Apply appropriate thread sealant or PTFE tape to male threads before assembly and tighten to a snug, leak-free fit using pipe wrenches. Verify orientation of the flat side of the eccentric reducer to match the intended flow and drainage requirements of the system.
