Value Collection MDG342 40 Malleable Iron Union 1-1/2 in

Product Description

The VALUE COLLECTION MDG342 40 is a Class 150 malleable iron threaded pipe union sized at 1-1/2 inches. It is designed for joining and disconnecting sections of threaded pipe in liquid, gas, and steam service lines. The union construction allows a pipe run to be broken without disturbing adjacent fittings or fixtures. Rated at 300 psi for liquid and gas service and 150 psi for steam service, this fitting suits a wide range of mechanical and process piping applications. Plumbers, pipefitters, and mechanical contractors typically install these fittings in commercial and industrial environments where routine line access is required.

This malleable iron union is appropriate for use in gas distribution piping, water supply lines, and low-pressure steam systems. The galvanized finish provides corrosion resistance suitable for exposed or damp mechanical room conditions. The threaded end connections conform to standard tapered pipe thread patterns, making this union compatible with standard Schedule 40 and Schedule 80 threaded pipe assemblies. It is sold in a package quantity of 5 units, which suits both single-job installs and stocking applications.
