What the BACK UP RING does
A back-up ring sits behind a seal and stops it extruding into the clearance gap under pressure. It carries no sealing duty itself — its whole job is to keep the seal in shape at the pressure peaks a percussion circuit produces on every cycle.
Signs it needs replacing
- Seal material extruded, nibbled or shaved at its edge
- Seal life much shorter than expected with no surface damage to explain it
- Leakage that appears only at high pressure
- Back-up ring found broken or spiralled
Before you fit it
Fit the back-up ring on the low-pressure side of the seal and the right way round; installed backwards it does nothing and the seal extrudes as though it were absent.
General guidance for this class of component. Always work to the torque figures, clearances and service intervals in your machine's own manual.
