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 mating of 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.
All SD 4000 Couplings are designed to be installed with a pre-set torque wrench calibrated at 80 inch pounds to accommodate the 305 stainless steel 3/8” Hex Head screw.
