6-Strap

• A super-duty stainless steel coupling for joining no-hub cast iron soil pipe and fittings
• Extra width for lateral support
• Additional sealing clamps for better load distribution and a more positive seal
• 304 stainless steel heavy-duty construction
• Shield color-coated orange

The Husky SD 4000 coupling has been engineered by Anaco to provide a super-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 and 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 additional sealing clamps yield increased surface bearing contact between the coupling and the pipe or fittings, thereby inhibiting joint movement at higher internal pressures not commonly associated with a DWV system.
