Abstract
ISO 16031-2:2003 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.
ISO 16031-2:2003 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.
Specifications for O-rings with an inside diameter up to 12,7 mm have been taken from ISO 16031-1, because the same tolerances are applicable to the O-rings in ISO 16031-2:2003.
