Description
Hydraulic Rod Seals Double Delta 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 a large range of temperature and media compatibility.
This Hydraulic Rod Seal Double Delta is designed to be used in existing dynamic o-ring grooves and doesn't require any groove modification. It is 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.
