A rubber expansion joint is a flexible connector designed to absorb noise, shock, vibration, and physical and thermal energy. It is made from natural or synthetic elastomers and may be internally reinforced with fabrics and metal for strength and pressure resistance. External metal reinforcement may also be used for movement control. Construction Terms for Rubber Expansion Joints Carcass: The body of the expansion joint consisting of fabric and/or interior metal reinforcement. Cover: The natural or synthetic rubber exterior that protects the carcass from damage. Fabric Reinforcement: A synthetic or natural fabric between the tube and cover that flexibly supports the expansion joint for movement or pressure. Metal Reinforcement: Solid rings or wire embedded in the carcass to strengthen the joint for high pressure or vacuum. Tube: A protective, leak-proof lining that extends through the bore to the flanges, preventing fluids from penetrating and weakening the carcass.
