Rod seal RSD 20x25x4 PU [2ERSD774]

The U Ring RSD 20x25x4 PU [2ERSD774] is a double-lip sealing ring, made of C0 polyurethane by the renowned Italian manufacturer Artic Seals. It was designed with hydraulic cylinders in mind. Thanks to the elasticity of the material, both lips are pressed against the cooperating surface, ensuring effective sealing. An additional lip stabilizes the seal and protects against external contamination. The ring's design prevents the stick-slip effect and supports the seal's operation at low temperatures.
