DRD is a double-acting low-friction rod seal solution for compact O-ring grooves, that extends the service range above what an o-ring alone is capable of supporting. The DRD is designed for light-duty applications, is particularly suited for small-diameter installations, and due to its size and design, is easy to install. High performance materials, provide outstanding wear and extrusion resistance properties as well as large range of temperature and media compatibility.

It designed to be used in existing dynamic o-ring grooves and doesn't require any groove modification. A good choice for pneumatic and hydraulic equipment sealing needs, the DRD is proven to extend the service range and seal longevity over stand-alone o-ring installations.

This seal is available in a variety of DSH high-performance materials to suit a wide range of demanding applications.
