Characteristics and performance

High-performance Armorlene® materials, like HLX, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility. The P54 has a proven design pedigree as a high-performance seal used in demanding applications.

The standard P54 seal face includes pressure notches, which makes the seal very responsive to changes in pressure or direction of travel. Used successfully for years in performance-critical applications in construction equipment, machine tools, material handling, agricultural equipment, and other industries, the Hallite P54 is a workhorse compact, double- acting, piston-sealing solution.

The seal’s design fits a variety of housing sizes, including ISO 7425-1 grooves, and is offered in a wide range of metric and inch options. Hallite recommends proper guidance be used with this seal in heavy-duty applications (see Hallite Bearings section).

Product details
