Standard O-rings are made from a variety of Parker-developed rubber compounds and compression molded into the shape of an O-Ring. Base polymers include polyacrylate (ACM), ethylene acrylate (AEM), butyl rubber (Isoprene, IIR), polychloroprene rubber (Neoprene), ethylene propylene rubber (EPM, EPDM), fluorosilicone, acrylonitriles-butadiene (Nitrile, NBR), hydrogenated nitrile (HNBR), polyurethane (AU), silicone, fluorocarbon (Viton, FKM), tetrafluoroethylene propylene (Aflas), high performance fluoroelastomers (Hifluor), and perfluorinated elastomer (Parofluor and Parofluor ULTRA).

Standard AS568 O-rings come in various size options ranging from 2-xxx, 3-xxx, 5-xxx to 8-xxx. Custom sizes are avialable as well, please contact us for more information.
