It was 1968 when MG Piping Products’ MG Coupling first hit the market. Since then, it has enjoyed a sterling reputation for being a joint of the highest strength possible, derived from tightening the nuts and bolts to 175 inch-pounds of torque. Actual installations and stringent laboratory tests have verified the high-strength capabilities of the corrosion-resistant, cast-iron MG Coupling, which consists of two cast iron clamps, a neoprene gasket and stainless steel nuts and bolts. Furthermore, many code jurisdictions have also recognized these capabilities.
