Quad rings, or X-rings, have four-lobed cross-sections reducing friction and spiral twist. They provide better sealing than O-rings in dynamic applications. The design distributes pressure evenly, reducing wear. Quad rings resist compression set better in rotary motion. They fit standard O-ring grooves, easing retrofitting. Their stability improves performance in reciprocating hydraul... https://globalsealstech.com/hydraulic-seals/
