Buffer Rings

Buffer Rings buffer the pressure spikes of hydraulic systems. They act as a primary rod seal, and at the same time enable trapped fluid sealed by the secondary seal, which is down stream of the buffer, to be pumped back into the system. When a buffer ring is used in combination with a lip seal, the resulting sealing system provides long life with an exceptionally dry rod. Buffer seals are commonly used for rod seal application only.

 


Daemar DMR Hydraulic Seals Buffer Ring

Style KR (standard)

Molded in PTFE with a rubber energizer, this seal absorbs the shock of pressure spikes protecting the rod seal.

Daemar DMR Hydraulic Seals Buffer Ring

Style DYR (standard)

DYR style buffer ring offers an asymmetric sealing lip profile, champhered sealing edges, and pressure relieving capabilities to prevent inner pressure entrapment when employed in a tandem sealing system.

Daemar DMR Hydraulic Seals Buffer Rings

Style RBS

The RBS style rod buffer seals are a rectangular urethane buffer ring designed to absorb pressure fluctuations thereby protecting the primary rod seal. Some sizes include a radial and axial slot, which faces the pressure, to relieve back pressurebetween the primary and buffer seal.
