How do backup rings help to prevent O-ring migration?
Backup rings are used for both static and dynamic fluid power applications and prevent the migration or extrusion of an O-ring in the gap as pressurisation and de-pressurisation/pressure cycling occur. The profile shape of the backup rings is usually rectangular but may also be concave at the face mating with the O-ring. Manufactured in various PTFE […]
