ASTON YP PISTON SEAL

    YP PISTON SEAL
    – A dynamic sealing element that ensures low friction, high speeds of operation and, thanks to the resistance chemistry of the material that exceeds those of all other elastomers, a high compatibility with almost all fluids.
    – A standard low deformation O-Ring permanent as an energizing element on the static part
     
    Features
    • Low static and dynamic friction, even in absence of lubrication
    • No “stick-slip” tendency
    • Small footprint and simple execution of the headquarters
    • Good resistance to extrusion
    • High compatibility with all fluids (with right choice of O-Ring material)
    • High permissible speeds
    • High temperature resistance
