Product detailed description
The double-acting K757 piston seal consists of one PTFE profile ring, one elastomer X-ring and two O-ring energizers. K757 is an improved version of K753, distinguished by a double O-ring that increases sealing performance by optimising preload. Like K753, K757 is the ideal piston seal for systems with two different media separated by the piston seal, such as liquid and gas.
Advantages
- Ability to work with different types of media, in liquid-liquid or liquid-gas systems
- Low friction
- Low gas permeability
- High resistance to various chemicals and high temperatures depending on the elastomer used
- Design providing good sealing performance at various pressures
- No stick-slip
- Long service life
- Resistance to high frequencies
Applications
- Piston accumulators
- Hydropneumatic cylinders
- Presses
- Loading platforms
