YRB PISTON SEAL
– A dynamic sealing element that ensures low friction, high speeds of operation and, thanks to the resistance chemistry of the material that exceeds those of all other elastomers, a high compatibility with almost all fl uids.
– A standard low deformation O-Ring permanent as an energizing element on the static part
Features
• Low static and dynamic friction
• High permissible speeds
• No “stick-slip” tendency
• It can also work with a simple effect
• 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
