Heavy-duty no-hub coupling
A quality line of large diameter no-hub couplings
Featuring 5/8 in W bands and 3/8 in hex head screws, provide optimum sealing force at 120 in-lb installation torque
Provides greater sealing pressure around pipes of larger diameter than do conventional clamps
Shield requires less band load to transfer pressure to the gasket, leaving more clamping load in reserve to compress the gasket
Features a laterally spaced pattern of multiple thick sealing sectors and adjacent groove sectors
When the clamps are tightened, this pattern permits the clamping bands and the shield to form a restriction impeding the movement of the shield relative to the gasket
A quality line of standard-duty couplings that are assembled in Mexico using USA steel and gaskets. Manufactured with the same high-quality as our other couplings, but at a lower price point. In full compliance with ASTM 564, CISPI 310 and ASTM C1277 and also carries IAPMO, Canadian Standard Association and NSF certification.
