About MG Piping Products Company:
The MG Coupling is a high strength, corrosion resistant, cast iron coupling used to join hubless cast iron soil pipe and fittings. It consists of two cast iron clamps, a neoprene gasket, and stainless steel bolts and nuts.
The high strength of the MG Coupling is derived from tightening the nuts and bolts to 175 inch-pounds of torque. Since its first use in 1968, the MG Coupling has consistently had the reputation of providing a joint of the highest strength available.
Many code jurisdictions have recognized the high strength capabilities of the MG Coupling by allowing hubless pipe and fittings joined with MG Couplings to be supported with hangers similar to lead and oakum hub and spigot installations. Actual installations and laboratory tests have verified the high strength capabilities of the MG Coupling.
