YL PISTON SEAL
– A dynamic sealing element that ensures low friction, high speeds operation and, thanks to chemical resistance of the material that surpasses those of all others elastomers, high compatibility with quasi all fluids.
– A standard low deformation O-Ring permanent as an energizing element on the static part.
Features
• Low static and dynamic friction, even in absence of lubrication
• No “stick-slip” tendency
• Small footprint and simple execution of the site
• Good resistance to extrusion
• High compatibility with all fluids (with right choice of O-Ring material)
• High permissible speeds
• High temperature resistance
