Parback® backup ring with a curved cross-section.
Parbaks are contoured on one face to minimize distortion of the o-ring when under pressure. Parbaks should be installed with the contoured face against the o-ring, but reversal does no harm.
- Excellent extrusion resistance
- Easily stretched for installation
- Lubrication is enhanced by rubber which absorbs system
fluid and does not plate out on rubbing surfaces

Hytrel backup ring with a flat cross-section.
Excellent extrusion resistance and tolerance to fluids such as phosphate esters, hydraulic oil, and water.
- Improved extrusion resistance compared to standard FKM or NBR backups
- Can be stretched over larger diameters and will return quickly to their original size
