OD Dynamic Seal

Series 413: OD Dynamic Seal

The 413 series seal is a robust profile, designed to work in both rotary and reciprocating applications. For high-pressure use, the 413 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 or metric sizes

Higher seal force due to seal design

Easy installation

Can retrofit existing O-ring grooves


The 413 series is suitable for rotary and reciprocating motion.

Typical applications include:

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

The 413 series Dynamic Seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, available up to 3000 mm in diameter, and MP50 injection-molded TPU. To suit a variety of applications, the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM
