Obduramus Umwelttechnik GmbH has developed a locking mechanism for Circum products in order to quickly and effectively repair pipe connections from DN 150 and up. This system is flexible and manufactured using high-quality materials. Lock rings and/or stainless steel sleeves are enclosed by EPDM seals and are kept pressed against the inner pipe walls using specially developed and patented tension locks. This system seals the damaged spot permanently and reliably.
