Fluid power systems. O-rings - Inside diameters, cross-sections, tolerances and designation codes1 Scope This document specifies the inside diameters, cross sections, tolerances and designation codes for O rings used in fluid power systems for general industrial and aerospace applications. The ISO 3601 series of standards basically addresses O rings with moulded cross sections without a radial joint. The dimensions and tolerances specified in this document are suitable for any elastomeric material, provided that suitable tooling is available.
