K26 is a double acting complete piston seal which consists of a steel plate vulcanized with elastomeric nitrile rubber using special production methods. The sealing lips do have springs in order to increase the preload.

PRODUCT ADVANTAGES
• Good sealing performance at low pressures due to the reason having spring on the sealing lips
• Long service life
• Ready to fit complete piston
• Also used in pneumatic systems

APPLICATION
Short stroke , low pressure hydraulic cylinder and special pneumatic cylinders.

Note: It is recommended to have 50% to 90% of the working surface material contact area value.

INSTALLATION
K26 is pushed onto the piston rod with the rubber layer on the clamping flange towards the rod and fixed by fastening. The nut has to be secured. The sliding surface and the cylinder bore should be oiled with an oil that must not go into the reaction with the sealing element during the installation process. Special precautions has to be taken at the end of the stokes to avoid damaging of the sealing lips.

NOTES
For special applications that require high temperatures , K26 can be produced in FKM material.
