Obduramus Circum-FLEX
For small to medium diameters
The Circum-FLEX stainless steel rehabilitation sleeve is equipped with the patented Circum lock from Obduramus. It is positioned at the damaged area using a packer and pressed against the pipe wall. By expanding the stainless steel sleeve, the EPDM seal is pressed against the pipe wall and the damaged area is permanently sealed. The Flexcuts enable flexible adaptation to the pipe wall, even with offsets.
Advantages of Circum-FLEX:
- Rehabilitation of offsets up to 20 mm
- Patented external lock
- No protruding obstacles
- Packer-friendly
- Completely assembled and ready to install
- Free from environmentally harmful lubricants

Special feature
The patented, external lock of the Circum-Flex internal renovation sleeve ensures a minimised cross-section reduction in the sewer and thus prevents debris flowing past from becoming trapped. The Flexcuts allow flexible adaptation to the pipe wall.
Application
Renovation of position deviations and offsets on joints.
Service
The system has been designed so that you as the user can install the sleeve yourself without having to purchase expensive technology. If required, we will train you directly on site.
