Mars 69029102026 Concentric Reducer 6x3 in 125 Lb Ci Flanged

Product Description

The MARS 69029102026 is a concentric reducer fitting rated for 125 lb cast iron flanged service. It transitions pipe flow from a larger diameter to a smaller diameter along a shared centerline, which maintains alignment in straight-run piping systems. The fitting measures 6 inches on the large end and 3 inches on the small end. Cast iron construction provides the durability and pressure handling required in commercial and industrial plumbing, steam, and hydronic piping systems. Licensed plumbers and pipefitters install this type of fitting during new construction and retrofit work where flanged connections are specified.

This concentric reducer is suited for use in commercial and industrial piping systems where 125 lb flanged cast iron fittings are called for. Typical applications include steam distribution, chilled water, hydronic heating, and process piping. The concentric design keeps the pipe centerline consistent, which is preferred in horizontal runs where drainage or flow alignment is a priority. Flanged ends allow for bolted connections that can be disassembled for maintenance without cutting pipe.

Key Features

• Concentric reducer design maintains shared centerline between inlet and outlet
• 6 x 3 inch size transitions large-diameter to small-diameter flanged pipe runs
• 125 lb pressure class cast iron flanged rating for commercial and industrial service
• Flanged ends allow bolted, field-removable connections
• Cast iron construction suited for steam, hydronic, and process piping applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 125 lb cast iron flanged piping systems requiring a 6 x 3 inch concentric reduction.

Installation Notes

Installation of flanged cast iron fittings should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the IPC and IFGC where applicable. Isolate and depressurize the system fully before breaking any flanged connection. Use appropriate flange gaskets rated for the service conditions and torque bolts in a cross pattern to ensure even seating. Do not over-tighten flange bolts on cast iron, as the material does not tolerate stress the way ductile iron or steel does.
