Products Description
X-Rings, also widely known as Quad Rings, are highly specialized four-lobed sealing solutions designed to outperform standard O-Rings in demanding dynamic and static applications. The unique cross-section provides double sealing lines, drastically reducing friction and operational wear while preventing the seal from spiraling or twisting in the groove. Whether utilized in reciprocating cylinders, rotary shafts, or complex hydraulic systems, our custom X-Rings deliver reliable, long-lasting, and leak-free performance under varying pressure conditions.
Product Features
Anti-twist & double sealing
The innovative four-lobed geometry requires less squeeze for an effective seal and inherently resists the tendency to roll or spiral within the groove during dynamic, reciprocating movements.
Low friction & extended wear
By distributing the sealing force across multiple contact points and retaining lubrication between the lobes, our Quad Rings minimize breakout friction and significantly prolong the component's service life.
Custom molded dimensions
Available in all standard AS568 sizes as well as fully custom-molded geometries, ensuring a precise fit for specialized hardware, pneumatic actuators, and heavy-duty hydraulic cylinders.
Certified OEM manufacturing
Backed by 20+ years of engineering expertise and ISO 9001/TÜV certified facilities, we formulate materials compliant with global standards (RoHS, REACH, UL, FDA, Prop 65) to meet your specifications.
