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