Product details

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 and the patented, bi-directional corrugation shield seals pressure in both parallel and transverse patterns on the gasket and pipe
  • Meeting the requirements of ASTM C564, the beaded gasket consists of an elastomeric compound with strategically positioned grooves and beads, when tightened, the shield attaches to the grooves to provide exceptional sealing p
  • The clamps feature a one-piece screw housing that mechanically interlocks to the band and this design eliminates leak paths that can occur in staked or welded clamps
  • Fastening the clamps to the shield, the floating eyelets allow the clamp, band and shield to move independently and this freedom prevents the shield from crimping and future leakage
  • 5/16" hex-head screw applies 60"-lb of installation torque to the band/shield assembly
  • 2 clamps per coupling
  • Corrosion-resistant, rustproof stainless steel shield and clamps
  • Preferred by professional plumbers nationwide
  • Packaged/sold individually
