The simple, effective way to connect exhaust system components. Pipes, mufflers and converters. Unique seal and high clamp loads are provided without permanent distortion to exhaust members. Exhaust connections are serviceable and easy to disassemble.Available in standard industry sizes from 44.5mm(1-3/4")through 152.4mm(6"). A serviceable joint. Unitized construction reduces part number complexity. Efficient use of materials reduces weight,and assembly costs. Unique fastening system stretches the band using its tensile strength permitting the use of thinner gauge,corrosive resistant materials. The reaction block provides a full 360 degree equal distribution of stretching force,prohibiting pipe distortion while completing a seal around the joined exhaust components.
