■ P Series Detailed Fitting Size
①To fix a plane: If an internal pressure is exerted, install O-Ring so that the perimeter of the O-ring contacts with the external wall of the groove; If an external pressure is exerted, install O-ring so that the internal circumference of the O-Ring contacts with the internal wall of the groove.
②To fix a plane in consideration of the internal pressure, provide a margin of 0.2~0.3mm for Dimension D where Dimension D is 30mm or less.
③Slot Dimension is for reference only.
