Product Description
X-Ring (JF4® sealing rings) are precision sealing components featuring a four-lobe cross-section that provides a double sealing line, making them particularly suited for hydraulic, pneumatic, and oleopneumatic devices. These rings are especially suitable for dynamic applications, such as reciprocating movements up to 150 bar or rotary movements up to 1 meter per second.
