DESCRIPTION
The PS1800 profile 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. The PS1800 is a two piece design comprised of standard size rubber square ring energizing a rectangular shaped PTFE cap.
The PS1800 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.
