The piston seal K757 is a double-acting seal consisting of a PTFE profile ring, an elastomer X-ring and two energizing O-rings. It is suitable for systems where the piston separates two different media, for example a liquid and a gas.

Benefits

• Works with different media (liquid-liquid, liquid-gas)
• Low friction without stick-slip
• Low gas permeability
• Good sealing under varying pressure
• Long service life

Field of application

• Piston accumulators
• Hydropneumatic cylinders
• Presses
• Loading platforms
