Characteristics and performance

The Hallite PCG is a double-acting, o-ring energized, low-friction piston seal designed for low- and medium-pressure systems. High-performance Armorlene® materials, like HLX, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility.

The compact design of the PCG piston seal provides an ideal sealing solution where housing space is limited.
