Product Description
Shanghai Qinuo’s AS568 standard rubber O-rings are widely recognized for their exceptional reliability and dimensional accuracy. These O-rings are essential sealing components used in automotive fuel systems, aerospace fluid transfer systems, industrial pumps, hydraulic valves, compressors, and instrumentation equipment.
We manufacture O-rings using top-grade elastomers including NBR, HNBR, FKM, FVMQ, and FFKM, each chosen for its resistance to high temperature, aggressive chemicals, petroleum-based fluids, ozone, and mechanical stress. FKM and FFKM O-rings offer superior chemical resistance for extreme environments, while NBR and HNBR are excellent choices for cost-effective and durable general-purpose applications.
The AS568 standard provides a complete range of ID, CS, and OD dimensions, ensuring compatibility with global equipment designs and simplifying part replacement. Our production follows strict ISO quality control, ensuring consistent hardness, surface finish, and compression set performance.
Whether you require sealing for static, dynamic, vacuum, or high-pressure systems, our AS568 O-rings deliver long-lasting, leak-resistant performance. Contact our technical team for assistance in choosing the perfect material and size for your unique application.
Feature
These materials provide exceptional resistance to heat, fuel, oil, sour gas, H2S, ozone, pressure, and aggressive chemicals, making them ideal for environments requiring long-term durability and stable sealing performance.
Application
Our FKM and FFKM O-rings provide outstanding sealing performance in aerospace fuel systems and chemical processing equipment, while HNBR and NBR are widely used in pipeline, automotive engines, hydraulic pumps, and industrial machinery.
