- Scope
- 1 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. NOTE The tooling most commonly available is based on 70 IRHD NBR shrinkage rates (see ISO 48). For materials that shrink differently from this standard NBR compound, a special mould can be required to maintain the mean diameters and the tolerance limits listed.
