Product Overview
Jinwo Quad Rings (X Rings) feature a four-lipped X-shaped cross-section for static and dynamic sealing applications. The grooves between the four sealing lips can retain lubricant. Compared with conventional O-Rings, the X-shaped profile provides additional sealing contact areas.
We offer two configurations: the NBR FKM Rubber Quad-Ring Series and the Low Friction Quad-Ring Series. Both are available in standard AS568 sizes and support OEM/ODM supply.
