YB PISTON SEAL
A dynamic seal element which assuresexceptional low friction and high speedperformance, high compatibility with nearlyall media due to the chemical resistance whichexceeds that of all other thermoplastics andelastomers. Side grooves ensure that pressureloads the energizing 0-Ring in all work
Features
• Low static and dynamic friction
• High permissible speeds
• No “stick-slip” tendency
• Small footprint and simple execution of the headquarters
• High compatibility with all fluids (with right choice of O-Ring material)
• High resistance to extrusion
• High temperature resistance
