SilverBack XL - Extended Flexible Couplings

Flexible Couplings Designed for Pipe Bursting & Ramming

As infrastructure across the nation increasingly requires maintenance, underground utilities agree that pipe bursting and ramming are effective trenchless solutions to repair failing or infiltrated pipes. With modern pipe bursting and pipe ramming equipment, pipelines can be replaced without excavation, making this trenchless technique progressively popular in underground pipe repair. But, what happens after the replacement? That’s where the Silverback XL comes in.

S1E’s newly-designed SilverBack XL is an extended flexible coupling specifically designed for pipe bursting and pipe ramming connections. Due to its extra-long length, tough PVC material and heavy-duty shear ring, this product is an ideal addition to any municipality and trenchless contractor’s pipe bursting or ramming equipment. Contractors will be able to easily connect the two pipes together without having to worry about soil conditions or tensile stressing altering the pipes structural integrity. Built to be stronger, longer and more durable than any coupling in the market, our customers feel confident knowing they only have to complete the repair once.
