Characteristics and performance
The Hallite PDS is a double-acting low-friction piston seal solution for compact o-ring grooves, that extends the service range above what an o-ring alone is capable of supporting. The PDS 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 Armorlene® materials, like HLX, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility.
Hallite’s PDS is designed to be used in existing dynamic o-ring grooves and does not require any groove modification. A good choice for pneumatic and hydraulic equipment sealing needs, the PDS is proven to extend the service range and seal longevity over stand-alone o-ring installations.
