Buschmann PipeXpander

The Buschmann PipeXpander is a professional hand-operated tool designed for expanding seam-welded round downspouts made from aluminum, copper, and zinc. By creating perfectly fitting expansion joints directly on-site, the PipeXpander eliminates the need for separate couplers, allowing sections of downspout to slide together quickly while maintaining a clean, professional appearance.

Featuring Buschmann's patented gear mechanism, the PipeXpander performs the expansion and return stroke automatically with minimal effort. Specially engineered roller geometries ensure smooth operation while preventing structural marks or deformation on the pipe surface. The result is a precise, uniform expansion every time.

Designed for single-person operation, the lightweight aluminum construction makes the tool easy to transport and comfortable to use on rooftops or at the fabrication shop. Whether you're manufacturing slip sleeves, extending downspouts, or fabricating custom drainage systems, the PipeXpander significantly improves productivity while maintaining exceptional finish quality.
