- Piston seal- DK 144
Piston seal DK144 is a bi-directional piston seal for use in medium to heavy duty hydraulic applications. It 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, depending on its cross section, by a single square energizer or dual O-rings. This piston seal is commonly used in applications such as mobile hydraulics, lift trucks, standard cylinders and piston accumulators.
