Description
The No-Hub Coupling has a patented shield design that provides maximum transfer of pressure from the clamps to the gasket and pipe. Engineered to connect no-hub cast iron pipe in applications, replacing the less – efficient hub and spigot. The shield adjusts to a variety of a pipes diameters and circumferences – eliminating leak paths. The patented, bi – directional corrugation shield seals pressure in both parallel and transverse patterns on the gasket and pipe to provide a positive, reliable seal. The distinctive yellow shield quickly identifies the Heavy-Duty MD Couplings and makes it easier for inspectors. 5/16" hex – head screw applies 80 in.-lbs. of installation torque to the band/shield assembly.
