Introducing the adaptive Boldan® 3D Connection Liner, the perfect solution for challenging installations.
Made with super flexible material, Boldan® 3D Connection Liners can stretch approximately 25 % of the stated size, ensuring they can adapt to any pipeline shape.

Installing the Boldan® 3D Connection Liner is a breeze and requires no special tools. All you need is a normal silicone bladder to get the job done.
Thanks to its undersized dimensions, the 3D Connection Liner stays in place better during installation than a regular Connection Collar.

Our selections include Connection Liners for all sizes of pipes and degrees of angles. We also manufacture products according to our customer's specifications.

Upgrade your trenchless system with the Boldan® 3D Connection Liner today and enjoy a more efficient and hassle-free installation process!
