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 1/4 in Nominal Inner Diameter | 1/8 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

Top-of-the-range twin lip rod seal designed to provide a dry sealing solution in heavy-duty applications.
The seal’s shell is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance.
The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The unique profile of the NBR energizer ensures the primary sealing lips maintain contact under low or no pressure situations while ensuring proper sealing at higher pressures.
The Hallite 621 also incorporates an acetyl anti-extrusion ring to withstand side loads and extreme pressure peaks even with the extrusion gaps.
