Two things are equally important for reliable performance of an O-ring seal: the right size and the right material. Parker’s new O-Ring Selector is an engineering design tool that enables users to make the right material and size selections easily, quickly and reliably – in a single application. This post explains how to select a material using the “Service Conditions & Material Selector.”

Fast and efficient selection of the right material using the “Service Conditions & Material Selector”
Selecting the right material for a specific application is a central step in assuring the functionality of an O-ring in the system to be sealed. The “Service Conditions & Material Selector” is focused on mapping the material-related application conditions.
Minimum input required for selecting the O-ring material
The “Service Conditions & Material Selector” is used to define the application conditions. The operating temperature range is the minimum input required before the subsequent calculations of the installation conditions and O-ring dimensions can be performed in the “Size Selector.” If already known, the desired polymer group and hardness of the material can be entered here as well.
When an entry is made into a data field the suitable sealing materials will automatically be displayed under “Product Matches. The desired material can be chosen by clicking "Select"
Detailed input in “Advanced Material Selector”
This is where users can describe the application in even greater detail. In the “Filter by Fluid Compatibility” search field, a wide range of media can be selected and combined as appropriate. The O-Ring Selector has access to a database with more than 2,500 different media for this purpose.
Required approvals and conformities can be selected by means of an appropriate filter as well. The search can either be sorted by groups or a specific certificate can be selected under “Individual Certifications” ranging from AM, DBL, FDA, ISO, MIL through to WL certificates.
To meet specific requirements – such as the recognition of installed O-rings on assembly lines – available materials can also be filtered according to their colors.
