The SilverBack XL flexible coupling from Source One Environmental is specifically designed for pipe bursting and ramming applications. Connecting clay to clay and clay to plastic pipe, the coupling sizes range from 4 to 12 inches, with custom options available. Its extra-long length, flexible PVC material and heavy-duty shear ring allows the coupling to fix pipe alignment problems while resisting heavy earth loads and shear forces. It will protect the pipe from thermal expansion and contraction, and unstable ground. Contractors can easily connect the two pipes together during the bursting process and feel confident that the connection only needs to be completed once. 877/412-4740;
