The Hallite R16 is a single-acting, o-ring energized, low-friction rod seal proven to be ideal in a variety of applications. The seal is made with our high-quality Armorlene® products combined with an elastomer energizer for superior performance. High performance Armorlene® materials, like HLX, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility.

Unlike other designs, the R16 can be used in tandem installations to provide optimum sealing in high-speed applications. The R16 is also commonly used as a pressure buffer seal protecting the primary rod seal from high-frequency pressure spikes that might be found in a system. This design also fits standard ISO 7425-2 grooves and is offered in a wide range of metric and inch options.

The part numbers listed below only show standard material options for both the face seal and energizer, where applicable. For a complete list of the material and energizer options along with part numbering structure, please see the complete PDF datasheet or click R16 Data Tables.
