Characteristics and performance

The Hallite RDS 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 RDS is designed for light-duty applications, is particularly suited for small-diameter installations, and due to its size and design, is easy to install. Highperformance Armorlene® materials, like HLX, provide outstanding wear and extrusion resistance properties as well as large range of temperature and media compatibility.

Hallite’s RDS 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.
