Rotary shaft lip-type seals incorporating thermoplastic sealing elements - Nominal dimensions and tolerances Ingestion-build-183511 Purchaser needs to specify longWhat is this standard about? ISO 16589 specifies seals utilizing sealing elements manufactured from suitably formulated compounds based on thermoplastic materials, such as polytetrafluoroethylene (PTFE). They are considered suitable for use under low pressure conditions. This part of ISO 16589 shows seal types and examples. It also specifies the nominal dimensions and tolerance of the seals, shafts and housings, as well as a dimensional identification
