o-ring gasket sizes

The size of the O-ring washer depends on its purpose and application. The dimensions of these washers are usually described by their inner diameter (ID), outer diameter (OD), and cross-sectional diameter (CS), which determine the suitability and functionality of O-ring washers. The following are examples of common O-ring washer sizes:

Inner diameter (ID): This is the diameter of the circular section inside the O-ring washer, usually expressed in millimeters (mm) or inches (inch).

Outer diameter (OD): This is the diameter of the outer circular section of the O-ring washer, usually expressed in millimeters (mm) or inches (inch).

Section diameter (CS): This is the section or thickness of the O-ring washer, usually expressed in millimeters (mm) or inches (inch).

Diameter tolerance: This is the allowable range of changes in inner and outer diameters, usually expressed in ±.

Hardness: The hardness of O-ring washers is usually expressed as Shore A or Shore D hardness, which reflects their elastic properties.

Please note that different types of O-ring washers can come in various sizes and specifications to meet different sealing requirements. To choose the correct size, you need to consider the specific requirements of the application, including inner diameter, outer diameter, cross-sectional diameter, as well as the required hardness and material.

Usually, you can find detailed dimensional information in the product description of the O-ring washer or in the documentation provided by the supplier. If you need a specific O-ring washer size, please contact the supplier who can provide you with products that meet the requirements.
