K18

K18 is a five piece double acting compact seal which consists of elastomeric sealing element, thermoplastic elastomer backup rings and thermoplastic guide rings. It is suitable with many hydraulic cylinders thanks to the design with low friction and superior static and dynamic sealing functionality.

Advantages

• Superior sealing performance and low friction with its special design
• No additional guide ring requirement at low and medium duty applications thanks to compact design
• Economical sealing solution
• Simple groove design at one-piece piston
• Long service life
• Easy installation thanks to cut guide and backup rings

Area of Application

• Agricultural machinery
• Construction machinery
• Mobile machinery
• Loading platforms
• Forklifts • Industrial cylinders
