is an engineering tool which offers O-ring material and size selection combined in one tool. Both are interlinked, thus ensuring the best possible combination of the calculated O-ring size and material choice.
The O-Ring Selector covers both imperial and metric standards.

The Advanced Material Selector allows you to specify your service conditions in even greater detail: For instance, you can select and combine the fluids which are relevant to your application by using the Filter by Fluid Compatibility search bar. This search and filter function searches a database of more than 2,500 different materials.

After selecting a material that fits your sealing application, you can continue by having the Size Selector calculate the O-ring dimensions and tolerances, considering even thermal expansion and volume swelling of the sealing element. The parameter dashboard in the Results section will immediately show you if the selected O-ring size is suitable for your application.
