N&N Supply Company, Inc is now stocking MG Couplings from 2 inch through 6 inch.
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.
