GUIDE Ring G04


Guide ring G04 is a non-metallic strip or ring for piston head of hydraulic and pneumatic cylinders and is installed in standardized housings according to ISO 10766.

Some G4 ring sizes have special dimensions and cannot be fitted into standard housings per ISO 10766 and are provided as an option for specific applications.

Guide ring G04 has chamfered profile edges to prevent the edge from pressing into the corner radii of the housing groove.
