The HUSKY® SD 4000 coupling has been engineered by anaco to provide a heavy-duty, all stainless steel coupling, balancing the desire for a more rigid joint with the need to provide a superior positive seal, which can accommodate possible disparities in the no-hub pipe fittings. This has been accomplished by manufacturing our coupling with a super-duty corrugated shield of sufficient width to accommodate additional surface bearing sealing clamps. The additional sealing clamps when torqued to 80 in-lb, offer two salient performance related features. First, the overall dimensional thickness of the clamp and shield, in conjunction with the additional width of the coupling, result in a more uniformly rigid joint, with the load being supported at both the outer edge of the coupling and the centerline of the joint. Second, the joint movement at higher internal pressures not commonly associated with a DWV system. The 1.5 in through 4 in diameter couplings consist of a 3 in wide corrugated 304 stainless steel shield in conjunction with four (4) the 5 in through 10 in diameter couplings consist of a 4 in wide corrugated 304 stainless steel shield in conjunction with (6) all SD 4000 couplings are designed to be installed with a pre-set torque wrench calibrated at 80 in-lb to accommodate the 305 stainless steel 3/8 in hex head screw.
