Rotary shaft lip-type seals incorporating thermoplastic sealing elements - Identification of visual imperfections best-seller BS 4162 determines the resistance1 Scope 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 defines and classifies typical surface imperfections that could impair the function of the seals, and is intended as a convenience for purchasers and manufacturers in their
