ASTON YRB PISTON SEAL

    YRB 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 fl uids.
    – A standard low deformation O-Ring permanent as an energizing element on the static part
     
    Features
    • Low static and dynamic friction
    • High permissible speeds
    • No “stick-slip” tendency
    • It can also work with a simple effect
    • Small footprint and simple execution of the headquarters
    • High compatibility with all fluids (with right choice of O-Ring material)
    • High resistance to extrusion
    • High temperature resistance
