DESCRIPTION

The PSQ profile is a bi-directional piston seal for use in medium to heavy duty applications. This seal has outstanding sliding properties with no stick-slip effect. The PSQ is a unique seal design that includes a rubber quad seal in the PTFE cap to ensure drift free performance. The PTFE cap is a stable rectangular shape and is energized by a single square energizer.

The PSQ piston seal is commonly used in applications such as mobile hydraulics, lift trucks, standard cylinders and piston accumulators.
