DESCRIPTION
The PS1850 profile is a bi-directional piston seal for use in medium to heavy duty applications and is suitable for sealing against hardened surfaces in pneumatic applications. The PS1850 is a two piece design comprised of standard size rubber square ring energizing a rectangular shaped bronze filled PTFE cap.
The PS1850 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.
The PS1850 piston seal can be used interchangeably with the PS1800 style piston seal.
