The SilverBack XL heavy-duty, extended flexible coupling from Source One Environmental is designed for the connection of common sewer pipe materials used in pipe bursting and ramming applications.

The coupling’s longer gasket, high-torque clamps, wide stainless steel shields and increased socket depth work together to provide greater support at the pipe joints.

“The SilverBlack XL creates permanent, strong pipe connections,” says Tony Dipzinski, product development manager. “The coupling allows contractors to connect pipes without having to worry about soil conditions or tensile stress altering the structural integrity of the pipe.”

The coupling is available in 4- to 12-inch sizes for clay-to-plastic and plastic-to-plastic connections. Source One Environmental also offers custom sizes for all common sewer pipe materials and diameters.

Made of flexible PVC, the coupling is able to fix pipe alignment problems and withstand heavy earth loads and shear forces. It also helps protect the pipe from thermal expansion, contraction and unstable ground conditions.

The product includes a gasket manufactured to exceed the material and performance requirements of ASTM C 1173 and CSA B602. It features a heavy-duty shear ring and six 316 stainless steel, high-torque clamps for corrosion resistance, increased sealing and greater protection against groundwater infiltration and sewer exfiltration.

Couplings are also environmentally friendly. Ninety percent of the PVC used in the couplings is recycled from scrap, and 85 percent of the steel used in the clamps is made from recycled steel. All components in the couplings are 100 percent recyclable. 877/412-4740; www.s1eonline.com.
