The Straub Repair Clamp is used to seal damaged pipes safely and reliably. You can also use it to repair a variety of pipe materials including steel, cast iron, ductile iron, PVC, and fibre cement.

This reusable repair clamp has a special lip that ensures a secure seal even on corroded surfaces. It’s suitable for large damaged areas up to 250mm wide.

Choose from one-piece and two-piece models with integral hand grips that enable quick and easy installation. Both are suited for pipes with an outside diameter at least as long as the clamp.
