Mars 69029102032 Concentric Reducer 10x8 in Ci Flanged

Product Description

The MARS 69029102032 is a cast iron concentric reducer with 125-pound-class flanged ends, sized at 10 x 8 inches. Concentric reducers are used to transition between two different pipe diameters while maintaining a shared centerline, which is important in systems where alignment and flow consistency matter. This fitting is suited for hydronic, industrial, and mechanical piping systems where cast iron flanged fittings are specified. Installation is typically performed by licensed plumbers or pipefitters working on commercial or industrial mechanical systems.

This fitting is designed for use in flanged pipeline assemblies where a reduction from a 10-inch nominal bore to an 8-inch nominal bore is required. The 125-pound flange class rating makes it appropriate for moderate-pressure water and steam piping applications in commercial mechanical rooms, industrial process piping, and HVAC hydronic distribution systems. The concentric design keeps the pipe centerlines aligned, which is the standard choice for horizontal runs and vertical pipe installations.

Key Features

• 10 x 8 inch concentric reducer maintains shared pipe centerline for precise alignment
• 125-pound-class flanged connection compatible with standard 125 CI flange bolt patterns
• Cast iron construction provides durability in commercial and industrial piping environments
• Concentric geometry supports consistent flow transition between pipe sizes
• Flanged ends allow for removable, bolted connections without pipe threading

Compatibility

Designed as an OEM-style flanged fitting for use in 125-pound-class cast iron flanged piping systems requiring a 10 x 8 inch concentric reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter. Isolate and depressurize the line section before removing or installing flanged fittings. Inspect flange gaskets and fasteners prior to reassembly, and torque flange bolts in a cross pattern following applicable mechanical code requirements. Reference ASME B16.1 and local plumbing or mechanical codes for flanged joint assembly standards.
