Mars 69029134869 Concentric Reducer 1-1/4 X 1/2 in Galvanized

Product Description

The MARS 69029134869 is a galvanized malleable iron concentric reducer designed to connect pipes of two different diameters in a straight, centered alignment. This fitting transitions from a 1-1/4 inch nominal pipe size down to a 1/2 inch nominal pipe size. The galvanized finish provides corrosion resistance for use in wet or humid environments. Concentric reducers are a standard component in piping systems across HVAC, plumbing, and mechanical applications. Licensed plumbers, pipefitters, and HVAC mechanics install these fittings as part of threaded pipe assemblies where a reduction in line size is required.

This reducer is suited for residential and light commercial piping systems where threaded malleable iron fittings are specified. It is commonly installed in water supply, hydronic heating, and general mechanical piping where a centered pipe transition is needed. The concentric design keeps both pipe centerlines aligned, which is preferred in horizontal and vertical runs where eccentric offset is not required.

Key Features

• Concentric design maintains pipe centerline alignment through the reduction
• Galvanized finish resists corrosion in wet and humid service conditions
• Malleable iron construction provides durability for threaded pipe applications
• Reduces from 1-1/4 inches to 1/2 inches nominal pipe size
• Standard threaded connection compatible with NPT pipe systems

Compatibility

Designed as an OEM-style replacement fitting for threaded malleable iron pipe systems requiring a 1-1/4 inch to 1/2 inch concentric reduction.

Installation Notes

Installation is performed by licensed plumbers or pipefitters working with threaded pipe systems. Shut off and depressurize the affected pipe system before removing or installing any fittings. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Follow applicable IPC and local mechanical code requirements for fitting selection and installation procedures.
