Our high-performance AEM (Ethylene-Acrylic Ester Rubber) O-Rings are engineered for the most demanding sealing environments in the automotive and industrial sectors. Specifically designed to withstand extreme temperature fluctuations and aggressive chemical exposure, these O-Rings ensure leak-proof integrity in critical systems including engine fuel lines, hydraulic brakes, and cooling circuits. By combining superior elasticity with advanced polymer science, we provide a sealing solution that prevents hazardous leakages and maintains system pressure under high-stress conditions.
Utilizing premium AEM synthetic rubber, these sealing components offer an exceptional balance of heat resistance, oil stability, and low-temperature flexibility. Whether integrated into turbocharger pipes, HVAC compressors, or aerospace fuel systems, our O-Rings are compliant with global environmental standards such as RoHS and REACH, ensuring that your operations remain efficient, safe, and environmentally sustainable while reducing long-term maintenance costs through extended component longevity.

AEM offers significantly higher temperature resistance (up to 175℃ compared to 120℃ for NBR) and better stability when exposed to hot engine oils and ATF fluids, reducing the frequency of seal failure in high-heat zones.
Yes, our AEM O-Rings are specifically engineered for refrigerant resistance, performing reliably with R134a and R1234yf without cracking or losing airtightness over 500+ hours of operation.
With a flexibility range down to -40℃, AEM O-Rings prevent leakage during cold-start conditions by maintaining their seal and elasticity, which is superior to many traditional ACM or NBR materials.
Absolutely. Our products are fully compliant with RoHS, REACH, PAHs, TSCA, and PFAS regulations, ensuring they meet the stringent safety and environmental requirements of global markets.
In aerospace, they are primarily used for aviation fuel system seals and high-temperature oil product seals around aero-engines where thermal stability and chemical resistance are non-negotiable.
A low compression set (≤25% at 150℃) means the O-Ring maintains its original shape and "push-back" force against the sealing surface, preventing leaks even after prolonged exposure to heat.
