Download Our Guide: O-Rings
O-Rings are the most widely used seals in modern industry, offering a simple yet highly effective solution for a wide range of applications. Their versatility allows them to function as double-acting seals, handling pressures exceeding 5,000 psi in both static and dynamic environments. Designed for ease of installation and exceptional durability, O-Rings provide an economical sealing option without compromising performance.
While their design may appear straightforward, selecting the right O-Ring requires careful consideration of size, material, and operating conditions. Standard O-Ring sizes follow Aerospace Standard 568, established by the Society of Automotive Engineers, with 349 available size variations designated by specific dash numbers. Choosing the appropriate compound involves evaluating factors such as fluid compatibility, temperature range, and required mechanical properties.
Performance requirements further dictate the choice of durometer, which determines hardness and pressure resistance. Higher durometer ratings are essential for high-pressure applications, ensuring long-lasting reliability. All materials undergo stringent quality control to meet specifications for government, military, space, automotive, FDA, UL, industrial, and commercial applications.
