    eFunda: Introduction to O-Rings

    An O-Ring is specified by its inner diameter, its cross-section diameter, its material hardness/durometer (typically defined by the Shore A hardness), and its material composition.. In order for an O-Ring to seal against the movement of fluid, it must be compressed when seated inside the gland.

    Hardness - O-ring

    The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound. 70-durometer hardness should be used whenever possible as it offers the best combination of properties for most O-Rings applications.

    Dimensional Tolerances for Rubber Molded Components .

    The type of rubber material, and particularly its durometer hardness, will determine if the part will experience substantial size change during its cooldown. Very soft rubber (15 to 30 durometer) will fall in a 3 to 4% shrink category. Firm to almost rigid compounds (65 to 85 durometer) will shrink 1-1/2 to 2%, allowing for tighter tolerances.
