Designed for use on one-piece solid pistons the KB09D is a modification of our KB09C profile, commonly used in hydraulic cylinders found in off-highway applications.

It is a double acting/bi-directional piston seal comprising of a central elastomeric sealing element and precision machined thermoplastic back-up rings which are split to allow assembly onto the solid piston.

The central sealing element provides initial radial compression upon installation to provide low pressure sealing, when subjected to system pressure the seal energises to provide further compressive force and leak tightness.
