The simple, effective way to connect exhaust system components. Pipes, mufflers and converters. Extra seal and clamp load performance to meet Or exceed durability requirements without Permanent distortion to exhaust membersAvailable in standard size from 50mm (2") to 89mm (3 1/2"). Improved clamp performance for applications with thicker pipe walls and larger pipe assembly gaps. Ideal for applications with limited packaging space. One assembly torque point. Unique fastener system efficiently converts band tensile strength into high clamp loads. The reaction block provides a full 360º equal distribution of stretching force, prohibiting a pipe distortion while completing a seal around the joined exhaust components.
