Polytetrafluoroethylene (PTFE) are closed,circular rings with annular cross section. The dimensions are – as with the elastomer O-Ring – characterised by the inside diameter ID and the cord diameter W (Figure ).PTFE O-Rings are not moulded but produced by machining. The rings can therefore be manufactured in all sizes.
