Hydraulic HBY PU buffer seals


Piston seals work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.


HBY is consists of a soft polyurethane seal and a hard black PA anti-extrusion ring added to the heel of the seal.


HBY is combined with the piston rod seal to absorb the impact and fluctuating pressure of high load, isolate high-temperature fluid and improve the durability of the seal. At the same time, the special shaped slot on the sliding lip can release the back pressure, which can eliminate the pressure between the piston rod seal and the buffer ring.


The installation of HBY can provide the maximum anti extrusion force under vibration pressure load.


Advantages:

1. Easy installation
2. Good Pressure and oil resistance.
3. Long life time.
