Polytetrafluoroethylene (PTFE) ORings are closed rings with an annular cross-section. They are not produced by molding but by machining and they can be produced in all sizes. Very good chemical resistance, compatible with most liquids and chemicals, with the exception of liquid alkaline metals and some fluorine compounds.
