U-Cups
Withstand the entire operating pressure of an application

U-Cups are also called rod seals or piston seals. U-Cups serve as an axial sealing element between the shaft and the housing, which can perform a rotational or translational movement. ttv offers a large variety of U-Cups, adapted to the following specific applications.
