K59 is a single acting pneumatic piston seal designed to have asymmetrical profile with shorter and thinner dynamic lip.

PRODUCT ADVANTAGES
• Easy installation
• Secure seating due to the longer and thicker static sealing lip
• Simple groove design and low axial housing height
• High sealing effect with cushioning applications

APPLICATION
Standard pneumatic cylinders.

INSTALLATION K59 can be snapped by hand into the housing grooves provided. In case of using an assembly tool make sure that it is of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil. Special lubrication should be used on the sliding surface in case of having dried media. NOTES For special applications that require high temperatures , K59 can be produced in FKM material. We recommend using guide ring or guide rings with K59 piston seal.
