The X-ring is composed of four lip seals with an X-shaped cross-section and can be used and handled in a manner very similar to O-rings. Additionally, it has excellent characteristics such as no possibility of twisting during reciprocating motion compared to conventional O-rings, lower contact pressure, lower friction, and longer lifespan. When there are issues with O-rings, using X-rings significantly enhances the sealing effect. Please feel free to inquire about special sizes, custom dimensions, and non-standard options. We have approximately 3,000 types of molds available, allowing us to offer low prices and short delivery times. For more details, please download the catalog or contact us.
