1-1/2" Heavy Weight No Hub CouplingMore 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 in/lbsStronger, more uniform scaling capacity - Axially slotted clamp bands tighten independently to accommodate most any variances in outside diameters of cast iron pipe and fittings being joinedHigher 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 flexibilityCorrosion resistant - 304 Series stainless steel combined with significant deflection factor makes this coupling highly dependable above and below groundSafe and easy to install - Flanged gasket helps maintain alignment during installation and tapered ends on shield reduce friction and prevent injury from sharp edgesVersatile - Internal profile of elastomeric sleeve against intermittent corrugation suits specific performance application of non-potable waste systems
