Our inserts are used as a supporting bush for the installation of PE pipes. The purpose of a supporting bush is to prevent the PE pipe from losing its form when mounting a grip coupling.

The inserts of Leenders Repair Clamps are unique because they consist of one part and do not have loose items. Due to an exceptional closing mechanism, this insert does not need a wedge and grinding down the remaining part of the wedge after installation is no longer required. Our inserts are available in a range between ø65mm to ø630mm with different wall thicknesses.
