Product Code:: PSO 0550 0440 042 CN
PSO/TTO/A123 TYPE PISTON SEAL
This seal type shows a double profile on
the dynamic side and a surface with two small steps
on the static side, where the o-ring is housed.
The presence of the o-ring, which energizes the seal,
ensures a perfect seal performance at low and
high pressure.
The special double profile avoids any
Hydro-dynamic pressure on the sealing part and the
consequent blow-by effect.
