Reliable Quality


Product introduction:


SD is a single acting seal consisting of a U shaped jacket and a helical wound corrosion resistant spring.

The helical ribbon spring of SD has a high spring loading, which gives excellent sealing integrity at low pressure and even in vacuum. SD is suitable for static applications and ideal in low speed applications.

  • - High contact pressure
  • - Excellent sealing integrity in gas and fluid applications
  • - Withstands rapid changes in temperature
  • - Good sealing ability when surfaces are not ideal
  • - No assembly tools are required for larger diameter seals
  • - Excellent resistance to ageing
Operation condition:

Pressure:         20 MPa ( dynamic )

                        80 MPa ( static )

 Velocity:         Up to 5 m/s ( Reciprocating )

Temperature:  -196°C to +260°C
