Hand-wrapped Rubber Expansion Joint
Our Hand-wrapped Rubber Expansion Joints are specially designed for large-diameter, non-standard, or high-movement applications. Unlike molded types, these joints are manually fabricated using reinforced rubber layers and customized winding techniques, ensuring strength, flexibility, and durability under demanding conditions. This product can be fully customized in size, shape, and length according to your specific project requirements. Whether it's an unusual pipe connection, large-scale industrial installation, or special movement compensation need, our hand-wrapped expansion joints offer a reliable and flexible solution.
