Characteristics and performance

The Hallite P16 is a single-acting, o-ring energized, low-friction piston seal especially useful where smooth movement and location accuracy is required. The P16 design is based on the very successful R16 rod-seal design which has been proven in the market to be an excellent seal. High-performance Armorlene® materials, like HLX, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and high-speed capabilities.

The P16’s design eliminates the potential for stick-slip and its very low running friction makes it ideal for high-speed applications. In particular, this seal is well-suited for use in piston accumulators in conjunction with other Hallite piston seals. The P16 is designed to fit a variety of inch and metric grooves, including ISO 7425-1 standard.

Product details

This seal is available in a variety of Hallite’s high-performance Armorlene® materials to suit a wide range of demanding applications. A tandem arrangement using the P54 or P16 in an Armorlene® material is effective in sealing high-frequency and long-stroke applications.
