Product Description
The HPS Piston Seal is a PTFE seal combined with a square seals energizers. The low-friction characteristics of PTFE combined with the performance abilities of the square seals make it able to provide a strong and efficient seal. The square seals design provides a robust sealing as it is less likely to slide or roll in the groove under the high speed and pressure of a double acting cylinder.
