Mars 69029102051 Eccentric Reducer 10x8 in 125lb Ci Flanged

Product Description

The MARS 69029102051 is a 10 x 8 inch eccentric reducer with a 125-pound cast iron flanged configuration. It is used to transition between two different pipe diameters in a piping system while keeping one side of the bore flat, which prevents air pockets from forming in liquid lines. The eccentric design is critical in pump suction applications where a concentric reducer would cause air entrainment and cavitation. This fitting is installed by licensed plumbers and pipefitters working on commercial or industrial piping systems.

This eccentric reducer is suited for commercial and industrial piping systems that require a diameter transition from 10 inches to 8 inches. The 125-pound flanged end connections make it compatible with standard Class 125 cast iron flange systems commonly found in hydronic heating, cooling, and process piping installations. It is typically installed at pump inlets, branch connections, or main-to-lateral transitions in wet piping systems.

Key Features

• Eccentric bore geometry keeps one side flat to prevent air accumulation in liquid piping systems
• 10 x 8 inch diameter transition for reducing main line to branch or equipment connections
• 125-pound cast iron flanged ends for compatibility with standard Class 125 flange systems
• Cast iron construction provides durability in commercial and industrial wet piping environments
• Flanged connection type allows for disassembly and maintenance without cutting pipe

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard Class 125 cast iron flanged piping systems requiring a 10 x 8 inch eccentric reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Depressurize and drain the affected pipe section before removing or installing any flanged fitting. Flange gaskets and proper bolt torque patterns should follow standard pipefitting practice for Class 125 connections. Orient the flat side of the eccentric reducer correctly relative to flow direction, typically flat-side up on pump suction lines to prevent air binding.
