Piston seal
Le Joint Français Pamargan Catelsa
Presentation
Pistons are components necessary for the operation of automatic gearboxes: they transform a hydraulic pressure into a force that activates clutches. They are composed of an insert onto which elastomer sealing lips are bonded.
Several armatures of the section that may have a very complex design, are insert-molded by a rubber specially adapted to high friction stresses.
Advantages
- Resistance to high pressures (up to 30 bars)
- Wide temperature range: -40 to +175°C
- Resistance to a very wide range of fluids
- Optimized friction (low hysteresis)
Applications
Automatic gearbox (AGB / AT)
Continuously variable transmission (CVT)
