Standard AS568 | ISO3601 | JIS2401|o-ring seal|ASTM D2000
We manufacture O-rings in a wide range of elastomer materials, including NBR, FKM, FFKM, EPDM, CR, HNBR, ACM, and Silicone (VMQ).
Our material formulations and physical property specifications can be developed and controlled in accordance with ASTM D2000, allowing us to meet specific performance requirements for different operating conditions and applications.
We manufacture both standard O-rings and custom, non-standard sealing solutions. With a comprehensive range of tooling, we support major international size standards, including AS568, ISO 3601, JIS, and Metric sizes, as well as customized dimensions.
Our O-rings are used across a wide range of industries, including Automotive, Semiconductor, Chemical Processing, Industrial Machinery, Food Processing, Hydraulics & Pneumatics, and Water Treatment.
From standard sizes to application-specific designs, we provide the right material, dimensions, and performance requirements for reliable sealing in demanding environments.
