U-rings are also called Y-rings. They are commonly used in hydraulic and pneumatic applications. They can be divided into pistons, piston rods, hydraulics, and pneumatics according to their uses. We mainly provide FKM, NER, HNBR, and EPDM materials, as well as non-standard Y-rings and U-rings for various uses and shapes.

Hydraulic seals

Sealing of hydraulic cylinder systems is achieved by highly efficient seals with complex shapes. We develop suitable materials that exhibit good wear resistance and offer a range of seals for common applications within hydraulic cylinders.

Pneumatic seals

We offer a wide range of pneumatic seals, dust seals, rod seals, piston seals and damping seals designed specifically for pneumatic applications. They work in dynamic applications, often in rotation and reciprocating motion, and at high speeds. In addition, rubber materials with internal lubricants are used to reduce wear and extend the service life of the seals.
