Product Summary

Dynamic sealing applications require O-rings that can withstand friction, wear, and repetitive motion. Our custom dynamic seal rubber O-rings are engineered to deliver exceptional performance in piston rods, hydraulic cylinders, and rotary shafts. With a material selection that includes NBR, FKM, HNBR, and silicone, we ensure low friction, high abrasion resistance, and excellent rebound. Leveraging our ISO9001 and IATF16949 certified processes, we produce O-rings that minimize leakage and extend maintenance intervals.

Each O-ring is tailored to your specific hardness, dimensions, and physical properties, ensuring a perfect fit for your assembly. Our 20 engineers work with you to optimize the seal design for your dynamic application, whether it involves high-speed rotation or reciprocating motion.
