K753 – PISTON SEAL
K753 double acting piston seal consists of one PTFE profile ring, one elastomer X-ring and an O-ring as energizer. K753 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
• Designed for grooves according to ISO 7425/1
• High resistance to variety of chemicals and high temperature with use of different elastomers
• High pressure resistance
• Design providing good sealing performance at variable pressures
• High wear resistance
• Long service life
Area of Application
• Piston accumulators
• Hydro-pneumatic cylinders
• Presses
• Loading platforms
