The chamfers facilitate assembly and protect the Oring from damage during the installation process The Oring and all surrounding parts should be well lubricated before assembly, preferably with the same fluid as used in the hydraulic system, ensuring compatibility with seals and cylinder components Extrusion gaps and backup ringsThis interactive guide helps you determine the chemical properties, temperature ranges and key uses of chemicals in ORing and seal productionAn Oring seal is one of the most widely used seal to block the clearance gap in the industry today It is also known as toroidal seal Oring seals are used in applications, ranging from garden hose couplings to aerospace or oil and gas duties due to the following advantages Wide application range (pressures, tolerances, temperatures, media)

It is a elastomer with a round crosssection designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interfaceThe squeeze or rate of compression is a major consideration in Oring seal design Elastomers may take up the stackup of tolerances of the unit and its memory maintains a sealed condition Orings with smaller cross sections are squeezed by a higher percentage to overcome the relatively higher groove dimension tolerances 3Rubber Seals, Sealing Devices & ORing Seal Design Apple
