Product Details

Description

This premium 1-1/4 inch by 3/4 inch reducing black malleable steel coupling is a vital component for plumbing and gas distribution systems. Designed to join two pipes of differing diameters, this reducer ensures a secure, leak-proof transition in residential and commercial appliance installations. Manufactured from high-tensile malleable iron, it offers the durability required for high-pressure gas lines, furnace connections, and water heater assemblies. Its black finish is specifically suited for gas and oil applications where galvanized fittings are restricted, providing a professional-grade solution for HVAC systems, boiler repairs, and industrial pipe fitting projects.
