Parbak is a Parker standard rubber back-up ring of contoured design. It is intended for use in dynamic and static seal applications.

Features of Parkbak rings:

• 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.
