4seal Classic

4seal Classic


4seal Classic transfemoral liner provides a secure suspension between the residual limb and the prosthesis. The silicone used is particularly skin-friendly and easy to clean while the Umbrellan fabric is designed to treat phantom pain. Four comfortable and flexible seals secure the liner without constricting tissue.

The liner can be turned inside-out and put on without using alcohol spray, providing more flexibility and independence.
