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.

90A Durometer | Buna-N Rubber Material | 15/16 in Nominal Inner Diameter | 3/16 in Cross Section | Backup Ring

Features

  • Excellent extrusion resistance
  • Easily stretched for installation
  • Lubrication is enhanced by rubber which absorbs system fluid and does not plate out on rubbing surfaces
