Obduramus Circum LEM
In the end, it’s all sealed.
The Circum LEM liner end sleeve which has been technically approved by the DIBt (German Institute for Structural Engineering). It works using compression theory and seals the liner ends in pipes. Enlarging the stainless steel sleeve presses the EPDM seal against the inliner and permanently seals it. The EPDM seal's special geometry ensures the bridging and sealing of gaps in damaged pipes.
Advantages of the Circum LEM:
- DIBt approval
- Patented external lock
- No protruding obstacles
- Packer-protecting
- Fully fitted and ready to mount
- Free from environmentally harmful lubricants

Feature
The external lock prevents the deflection roller from damaging or even removing the liner end sleeve when pipes are being cleaned.
Application
Connecting and sealing liner ends on pipes and structures, protecting vulnerable liner ends.
Service
The system was designed to allow the user to install the sleeve themselves without needing to purchase expensive technology. Direct training from us at the site of installation can be provided on request.
