Metric Silicone O-Rings

Metric O-Rings are employed in specialized applications and, like the name suggests, are standardized by metric dimensions. With a wide variety of sizes available, Metric O-Rings fill in the gaps left by the standardized AS568 o-ring chart. Metric O-Ring sizing is determined by the o-ring's inside diameter and cross section width.

This elastomer possesses mechanical properties similar to Viton®, with the exception of its slightly lower compression set resistance. It is more suitable for sensitive applications where lighter compressive forces are applied to energize the seal. This core has a Shore A hardness of 70 but it also offers a broader operating temperature range of -80°F to +500°F. (-62°C to +260°C).
