574-014 90A Buna-N Rubber Backup Ring | 1/2 in ID 1/16 in CS

10 EA IN STOCK*

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.
