Product Q&A

Q:How Does The Special Slit Lip Of HBY Buffer Ring Work?

The shaped slit lip releases trapped back pressure to hydraulic circuit, eliminates pressure buildup between buffer ring and rod packing, avoiding seal damage from sudden pressure spikes.

Q:What Matching Parts Need To Be Used With HBY Buffer Ring?

It must be installed together with main rod packing (U-cup rod seal) on hydraulic cylinder rod side, forming complete pressure buffer sealing system for heavy-duty hydraulic equipment.

Q:What Machines Can This HBY PU Buffer Ring Be Applied To?

Fit all hydraulic cylinder equipment including excavators, loaders, truck cranes, bulldozers, mining machinery, marine hydraulic devices and industrial hydraulic lifting platforms.
