K50 is a single acting pneumatic piston seal designed to have asymmetrical profile with shorter and thinner dynamic lip

PRODUCT ADVANTAGES
• Secure seating due to the longer and thicker static sealing lip
• Low friction and good sealing performance due to the seal geometry
• Wide range of dimensions
• Simple groove design

APPLICATION
Standard pneumatic cylinders.

INSTALLATION K50 can be snapped by hand into the housing grooves provided. In case of using an assembly tools 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 , K50 can be produced in FKM material. We recommend using guide ring or guide rings with K50 piston seal.
