Piston seal 90x74.5x6.3 PSQ
Product Code:: PSQ 0900 0745 063 CN
PSQ/A110 TYPE PISTON SEAL
This seal has a double point profile in the
in the dynamic part, and two small steps in
the static part where the Q-ring is housed.
The Q-ring energizes the seal and provides a perfect
sealing performance at low and high pressure.
The shape of the central double profile
prevents hydrodynamic pressures on the seal and
the resulting blow-out effect.
