Buffer Seals

Oz Seals

Buffer Seals

All Oz Buffer Seals maintain sealing contact in sliding motion between the cylinder head and the piston rod. The Oz Buffer Seals  are for easy installation and the designs are used in both rod and piston applications.

The Oz Buffer Seals are wear resistant and have a wide temperature range. Oz Buffer Seals comes in many different profiles and in a wide range of materials.  For sizes and direct orders, visit Sealnet.
