Characteristics and performance

The Hallite G54 is a double-acting, o-ring energized, low-friction piston seal that performs well in both high and low-pressure systems. Its design has square-cut edges and is often preferred in glass-filled high-performance Armorlene® materials, such as HQ6 or 701, to provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility.

Used successfully for years in challenging applications in construction equipment, machine tools, material handling, agricultural equipment, and other industries, the Hallite G54 is a proven compact, double-acting piston sealing solution. This seal is available to fit a variety of housing sizes, including the ISO 7425-1 grooves. Hallite recommends proper guidance be used with this seal in heavy-duty applications (see Hallite Bearings section).
