Mars 69029134850 Concentric Reducer 1-1/2 X 3/4 in Malleable Iron

Product Description

The MARS 69029134850 is a black malleable iron concentric reducer fitting designed to connect pipes of different diameters in threaded piping systems. It features female National Pipe Taper (FNPT) threads on both ends and transitions from a 1-1/2 inch nominal inlet to a 3/4 inch nominal outlet. Rated at 300 psi and classified at 150 lb pressure class, this reducer is built for reliable service in demanding plumbing and mechanical applications. The black finish is standard for non-galvanized malleable iron fittings used in gas and liquid piping systems. It is installed by licensed plumbers and pipefitters working on commercial and residential mechanical systems.

This concentric reducer is suited for residential and light commercial piping installations where a threaded reduction is needed between two pipe sizes in-line. Common applications include water supply lines, steam systems, gas distribution piping, and mechanical room installations. Its concentric design keeps the pipe centerlines aligned, which is important in tight or structured pipe runs. Domestically manufactured, it meets the dimensional and material standards expected in trade plumbing work.

Compatibility

Designed as an OEM-style replacement and standard fitting for threaded malleable iron pipe systems using 1-1/2 inch to 3/4 inch nominal pipe sizes with FNPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) as required by the system type. Shut off and depressurize the piping system completely before removing or installing any fitting. Apply an appropriate pipe thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque.
