YAB 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.
Features
Low static and dynamic friction
High speed allowed
No tendency of stick slip
Space saving construction and simple groove design
High compatibility with nearly all fluids (withthe right choice of O-Ring material)
High resistance against extrusion
High temperature resistance
