Back-Up Ring Praedifa Series V0709-90, Fluoroelastomer, 90 Shore A, Broad Applicability, Black, Parbak®

Brand: Praedifa

Parbak® back-up rings are made from hard elastomers and prevent migration of O-rings into the sealing gap when subjected to high pressures.

Parbak® is a Parker standard rubber back-up ring of contoured design which improves the sealing effect and increases service life. It is intended for use in dynamic and static seal applications.
Features
• Elastic memory permits Parbak® rings to be stretched into place for assembly without preconditioning or cutting
• Continuous construction prevents damage to the O-ring seal
• Lubrication is enhanced by rubber which absorbs system fluid and does not plate out on rubbing surfaces
• For a wide temperature range from -25 °C to 200 °C
• Compatible with a wide range of fluids
