Benefits

The specific surface pressure is reduced by plating the piston skirt all the way to the seal groove, thus resulting in very long service life
Reduced running clearance of the piston due to small radial thickness of the PTFE laminated piston and the resulting low thermal expansion
Reduced running clearance largely prevents piston slap, resulting in significantly smoother operation
Improved thermal transition from the metal piston to the cylinder wall due to the minimal thickness of PTFE laminated piston and the large contact surface

Application Fields

In dry-running compressors as plunger piston guide for compressing 100% oil-free air
To achieve minimum friction and to serve as an optimum guide for low-lube operations
Armature plating for solenoid valves
Piston plating for gas meters
