    The Caterpillar-specific 2-piece piston seal is a bi-directional piston seal for use in medium to heavy duty hydraulic applications and is suitable for sealing against hardened surfaces in pneumatic applications. This seal is a two piece design comprised of rectangular or square rubber square ring energizing a rectangular shaped PTFE cap.
    This profile offers excellent stability, long wear, low friction and extrusion protection. The seal is commonly used in applications such as agriculture hydraulics, mobile hydraulics, machine tools and hydraulic presses.
    Most commonly used on Caterpillar equipment and in Caterpillar kits.
