Technical guide: How to identify hydraulic seals: types, dimensions and materials

The back-up ring fits in the same groove as the O-ring, on the side away from the pressure (or on both sides if the pressure alternates). It stops the O-ring being forced into the gap between the parts when the pressure is high or the clearance is large, which is what cuts it.

  • Inside diameter: from 4.1 to 289.3 mm
  • Thickness, matching the O-ring cross-section: 1.6, 1.78, 2, 2.4, 2.62, 3, 3.53, 4, 4.5, 5.33, 5.7, 6 and 6.99 mm
  • The inch-based sizes (1.78, 2.62, 3.53, 5.33, 6.99) follow the AS 568 O-ring series; the others are metric
  • Rings are in NBR 90 or PTFE, depending on the size

Choose by the inside diameter and cross-section of the O-ring it supports. If you have the groove drawing, check there is width for both the O-ring and the ring.
