Product Details
Â
Standard material: sealing ring: polyurethane PU, retaining ring: nylon PA
Scope of application:
This product is used in combination with piston rod seals to absorb shock and fluctuating pressure under high load, isolate high-temperature fluid and improve the durability of seals. It can be used for power shovel, wheel loader, bulldozer, truck crane, wheel crane, dump truck, etc
Â
Features:
The special shaped slot on the sliding lip that can discharge back pressure can eliminate the pressure between the piston rod seal and the buffer ring.

Hydraulic seal kit- Buffer seals/buffer rings
Â
HBY buffer ring does more then normal buffer ring does, not only just buffer the pressure spikes of hydraulic systems, but also acts as a primary seal and pressure spike suppressor. It is mainly used in construction machinery cylinder.
