Aerospace fluid systems. O-Rings, inch series. Inside diameters and cross sections, tolerances and size-identification codes - Standard tolerances for non-hydraulic systems Ingestion-build-190310 NOTE 2 Recommended batch inspection1 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 intended for use in non hydraulic systems. This part of ISO 16031 is applicable, provided that suitable tooling is available, to O rings made from all other elastomeric materials other than nitrile and ethylene propylene materials, for which ISO 16031 1 specifies the dimensions.
