Trelleborg Sealing Solutions has developed a proprietary polyurethane compound called Zurcon Z25. It is recommended for all hydraulic applications where high temperature performance is required due to its improved extrusion resistance and compression set.

  • Operating temperature up to 130 C/270 F
  • Heavy duty cylinder sealing applications include industrial and mobile applications with limited cooling systems or cylinders exposed to high-temperature painting processes
  • Self-energizing, operates at pressures up to 40 MPa/ 5,800 psi without a Back-up Ring
  • Features an MDI (diphenylmethane diisocyanate) material base 
  • Suitable for rotary applications such as swivel joints, where heat is generated by high pressures and low speeds
