YB

The piston seal type Aston Seals YB is composed of:

  • A dynamic seal element which assures exceptional low friction and high speed performance, high compatibility with nearly all media due to the chemical resistance which exceeds that of all other thermoplastics and elastomers. Side grooves ensure that pressure loads the energizing O-Ring in all work conditions
  • A standard size O-Ring with low permanent deformation as energizing component on the static side
  • Low static and dynamic friction
  • Highspeedallowed
  • No tendency of stick-slip
  • Space-savingconstructionandsimplegroove design
  • High compatibility with nearly all fluids (with the right choice of O-Ring material)
  • High resistance against extrusion 
  • High temperature resistance
