Buffer Ring Seals.

Oz Seals Buffer Seals are designed to maintain sealing contact in sliding motion between the cylinder head and piston rod, protecting the system against pressure spikes and extending the life of the primary rod seal. Easy to install and versatile in design, they can be used in both rod and piston applications.

In many systems, rod seals are paired with buffer seals to form a complete rod sealing solution—delivering reliable performance, reduced wear, and improved service life in demanding hydraulic applications.
