K501 is a two piece double acting piston seal consisting of a thermoplastic sealing element and one energizer elastomer ring.

ADVANTAGES
• Excellent sealing performance under static and dynamic applications
• Simple groove design
• Easy fit without installation tool
• Superior sealing performance at high and variable pressure levels
• Longer service life due to high abrasion resistance
• Excellent sealing at high surface roughness
• Outstanding resistance to pressure shocks

APPLICATION
Heavy duty cylinders and construction machinery.

Note: It is recommended to have 50% to 90% of the working surface material contact area value.
INSTALLATION
Easy installation into one-piece piston head. Sealing elements must be pre-lubed with system oil before installation.
NOTES It is recommended to use with minimum two piston guide rings in long-stroke cylinders , minimum one guide ring in short stroke and under low radial loads.
