Parker 5-XXX Series Size Chart. Parker Hannifin has established the 5-XXX series for a number of commonly used o-rings sizes which do not fall in the AS568 line of o-rings and are also not true “metric” sizes. The chart below lists all of these sizes with their corresponding dimensions in inches and millimeters for easy identification.

Back-up rings are anti-extrusion elements designed to prevent the migration of sealing material into the extrusion gap under the system pressure. They are open or closed shapes for snap assembly made of a wide range of compounds which are highly resistant to thermal or mechanical stress.
