Description
K757 double acting piston seal consists of one PTFE profile ring, one elastomer X-ring and two O-ring energizers. K757 is the superior version of K753 and differentiates with the double o-ring design which increases sealing performance by optimizing the preload. Similar to K753, K757 is an ideal piston seal for systems which has two different media in the system seperated by the piston seal such as fluid and gas.
Advantages
• Able to work at variable media types, liquid-liquid or liquid-gas systems
• Low friction
• Low gas permeability
• High resistance to variety of chemicals and high temperature with use of different elastomers
• Design providing good sealing performance at variable pressures
• Stick-slip free
• Long service life
• Resistance against high frequencies
Area of Application
• Piston accumulators
• Hydro-pneumatic cylinders
• Presses
• Loading platforms
