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 | 2 1/8 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
AN wipers are ideal for light duty and pneumatic applications. Its main purpose is to prevent dirt and contaminants from entering the hydraulic or pneumatic systems. Suffix “SH” designates slotted heel design, “V” designates fluorocarbon material, and “B” designates carboxilated nitrile material.
