Mission Rubber No-Hub 304L Stainless Steel Heavy Duty Coupling




  • Corrosion resistant - 304 series Stainless Steel combined with significant deflection factor makes this coupling highly dependable above and below ground
  • Greater surface load bearing - wider 304 series Stainless Steel shield accommodates additional sealing clamps to provide for greater load bearing contact
  • Higher resistance to shear forces - rugged construction, excellent sealing properties and the arrangement of intermittent corrugations in the outer Stainless Steel band provide resistance to shear forces and help alignment while maintaining flexibility
  • More effective joint movement restraint - Stainless steel strap bands are 12.5% thicker than on traditional no hub couplings providing a positive seal when properly torqued to 80"/lbs
  • Safe and easy to install - flanged gasket helps maintain alignment during installation and tapered ends on shield reduce friction and prevent injury from sharp edges
  • Stronger more uniform sealing capacity - axially slotted clamp bands tighten independently to accommodate most any variances in outside diameters of Cast Iron pipe and fittings being joined
  • Versatile - internal profile of Elastomeric sleeve against intermittent corrugation suits specific performance application of non-potable waste systems
