K752 – PISTON SEAL
K752 is a double acting rotary sealing element consisting of a PTFE ring and an energizer elastomer o-ring. It provides high performance with the superior properties of PTFE material in piston type pressurized rotary sealing applications.
Advantages
• High wear resistance
• Low friction and stick-slip free
• Good dynamic and static sealing
• Long service life
• High extrusion resistance
• High resistance to chemicals and high temperature with use of different o-ring material
Area of Application
• Rotary tower systems
• Rotary joints
• Hydraulic distributors
• Mobile machinery
