The Chicago Fittings M597C74S166 is a precision-engineered transition coupling designed to join a 1¼″ SDR 10 plastic pipe (with .166″ wall) to a threaded 1¼″ male NPT steel or iron pipe. Constructed from high-strength ductile iron and internally coated to resist corrosion, the coupling features an IPS socket meeting industry pressure ratings and a threaded end fabricated to ANSI B1.20.1 standards. The interference-fit design ensures leak-tight connections without additional components.
