• Heavy-duty no-hub coupling Same as super heavy-duty, but with a 5/16 in hex head screw Value engineered alternative to the HD green shield Requires less band load to transfer pressure to the gasket, leaving more clamping load in reserve to compress the gasket The bi-directional corrugations create clamp sealing pressure in both parallel and transverse patterns on the gasket and pipe, thereby avoiding pull-out failures and providing a positive, reliable seal 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 Featuring 9/16 in W bands and 5/16 in hex head screws, provide optimum sealing force at an 80 in-lb installation torque

Ideal Tridon® iconic heavy-duty Yellow Shield® no-hub coupling provides all the performance of a super heavy-duty coupling but at a lower price point, due to using a 5/16 in hex head screw. Made in USA. In full compliance with ASTM 564, ASTM C1540, FM1680 (Class 1 and 2) and carries IAPMO, Canadian Standard Association.
