Figure Number: Heavy Duty NO-HUB Coupling
HI-TORQ™ 80 clamps offer a unique flexible rigidity that provides the strength required to maintain hydrostatic integrity even under severe stress. Feature a slotted design to compensate for mismatched pipe/ fitting diameter and maintains alignment and resists shear forces in demanding below grade applications.
HI-TORQ 80 couplings have just two clamps for sizes through 4" (100 mm) and only four clamps on sizes 5" (125 mm) to 10" (250 mm) — that means quicker installation. HI-TORQ 80 does not compromise on performance and reliability: Shields are 28 gauge type 304 18-8 chromium nickel stainless steel for exceptional corrosion resistance. One piece molded neoprene gasket complies with ASTM C-564 and features two sets of sealing beads and a unique inter-locking design for greater seal area and stability. Worm drive clamps are 304 stainless steel with 305-SS screws to provide maximum corrosion resistance.
