Rubber expansion reducer Concentric Reducer Get your big pipes and small pipes together, and reduce noise and vibration at the same time. Also called a tapered expansion joint, the Concentric Rubber Reducer connects unequal size pipes that share a common centerline. These joints eliminate the need for metallic reducers and at the same time provide sound and vibration isolation and expansion compensation. A high strength synthetic fabric is used to reinforce the body. Flanges are drilled to standard ANSI dimensions and all joints are provided with metal retaining rings.   Concentric Reducer (For eccentric configuration Style 100E, contact Metraflex.)
