Non-axial restraint pipe coupling

STRAUB-CLAMP

In single-part and twopart design for reliable repair of gas, water and waste water pipes made of different materials. Repair Clamps provide a safe and reliable sealing of damaged pipes made of a wide range of materials. The STRAUB-CLAMP repair clamp is manufactured with the standard seals out of EPDM resp., NBR The repair clamp must be at least as long as the outside diameter of the pipe being repaired.
