YRB

The piston seal type Aston Seals YRB, used preferably for hydraulic joints and rotary joints, 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
  • A standard size O-Ring with low permanent deformation as energizing component on the static side
  • Low static and dynamic friction
  • High speed allowed
  • No tendency of stick-slip
  • Can also work for single action
  • Space-saving construction and simple groove design
  • High compatibility with nearly all fuids (with the right choice of O-Ring material)
  • High resistance against extrusion 
  • High temperature resistance
