An o-ring is a toroidal elastomeric sealing device designed to prevent the passage of fluids or gasses between two mating surfaces under static or dynamic conditions. Its cross-sectional circular geometry creates a compression seal when installed in a properly dimensioned gland or groove. An elastomeric material’s inherent resilience allows it to conform to surface irregularities, maintaining seal integrity across a wide range of pressures, temperatures, and chemical environments.
O-Rings function based on the principle of zero-gap sealing, where the compressive force exerted by the mating surfaces deforms the o-ring, creating a barrier against leakage. This elegant yet highly effective sealing solution finds widespread application across numerous industries, from aerospace and automotive to medical sectors.
Apple Rubber employs a state-of-the-art approach to o-ring procurement and production, maintaining one of the industry’s most extensive and diverse inventories. Our vertically integrated manufacturing process, featuring in-house tooling and production capabilities, enables rapid prototyping and accelerated delivery timelines.
We adhere to aerospace standard AS568 and ISO 3601 for metric configurations, ensuring precise dimensional tolerances. These standardized sizes offer optimal availability and are recommended for new engineering designs. Our advanced CAD tools facilitate groove design for both static and dynamic sealing applications.
