PSN TYPE PISTON SEAL
The PSN type piston seal has been designed for
both hydraulic and pneumatic applications.
Due to its elasticity can also be assembled on
monoblock piston type.
Its main characteristic is an exceptional
smoothness that allows to use this seal even with
low lubricity fluids such as air and water.
Pressure: < 250 bar
Speed: < 4 m/s
Temperature: from - 30° C to + 120° C
Fluids: mineral hydraulic fluids
The sealing element’s material is a technopolymer
with high elasticity, whereas, for the energizing
element, it is proposed O-ring in NBR 70 Shore A.
Alternative material is bronze filled PTFE for the
sealing element and, for the energizing element,
O-ring in HNBR or FKM.
