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.
