ID Dynamic Seal

Series 409: ID Dynamic Seal

The 409 series seal is a robust profile, designed to work in both rotary and reciprocating applications. For high-pressure use, the 409 series can be combined with a back-up ring.



Replaces standard O-rings

Long life due to robust design

Will not roll during installation

Available in inch and metric sizes

Higher seal force due to seal design

Easy installation

Can retrofit existing O-ring grooves


The 409 Series is suitable for rotary and reciprocating motion

Typical Applications include:

  • Steel Aluminum Processing
  • Hydraulic Cylinders
  • Marine
  • Injection Molding Machinery
  • Oil and Gas
  • Machine Tool

The 409 series dynamic seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, available up to 3000 mm in diameter. To suit a variety of applications, the series is also available in NBR, HNBR, EPDM and high temperature-resistant FPM.
