Calder Style Bushing
Connect Any Pipe Size: Calder Style Transition Bushings
Calder Style Bushings/Filler Rings provide the essential solution for creating reliable transitions between pipes with dissimilar outside diameters. These removable EPDM rubber inserts fit precisely into couplings, eliminating the complexity traditionally associated with connecting different pipe materials and sizes. Designed specifically for civil engineering, municipal, and plumbing applications, these bushings create strong, lasting joint connections without specialized tools or techniques.
With an extensive selection of sizes available, Joints offers both standard stocked smaller bushings and custom-manufactured larger diameters (10 inch and up) made to order. These versatile components are engineered to work with virtually every pipe material in the field, including clay, asbestos cement, cast iron, ductile iron, and various plastics—ensuring professionals have the exact solution needed for every transition challenge encountered in infrastructure projects.
