Aerospace fluid systems. O-rings, inch series. Inside diameters and cross sections, tolerances and size-identification codes - Close tolerances for hydraulic systems1 Scope This part of ISO 16031 specifies the inside diameters, cross sections, tolerances and size identification codes for inch O rings used in aerospace fluid systems. The dimensions and high precision tolerances specified in this part of ISO 16031 are suitable for nitrile and ethylene propylene materials intended for use in high pressure hydraulic fluid systems provided that suitable tooling be available.
