Chesterton’s 7K SuperCup are piston cups for Hydraulic and Pneumatic* applications. Super Polymer 7K’s are supplied with a supporting metallic disc, molded into the base. The resulting rigid base provides a stable, non-distorting superior seal. Chesterton offers a Double Acting 7K which performs best in compact design situations.
- Long life cup will not swell, deform, drag or bind.
- Positive, flared lip design optimizes sealing forces.
- Excellent memory retains lip flare. Ideal replacement for traditional materials generally used on these applications.
- AWC 800 95A Super Polymer is the ideal material for the majority of applications.
