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. The G54 has a proven design pedigree as a high-performance seal used in demanding applications.

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.
