Products24 25O-ringProduct overviewImperial O-ringsBS214NBR70-36624The most common type of static seal is the flexible elastomer O-ring. O-ringsprovide an affordable seal that in most cases are simple to install and subject tocorrect material selection, give acceptable life between maintenance checks.Available in a variety of materials to suit every sealing application, fully mouldedO-rings are manufactured to several international sizes standards, includingBS1806, BS4518, AS568 and ISO 3601. Alternatively non-standard customsizes, up to 2.5m (8ft) diameter can be produced to specific requirements.compound REFERENCE36624hardness70 °IRHD ±5MATERIAl family designatorNBR NitrileO-ring Standard CompoundsElastomerNitrile, NBR,Buna NEthylene Propylene,EPDM, EPMMaterialFamilyDesignatorCompoundReferenceColourHardness°IRHDNBR 36624 Black 70EP 55914 Black 70EP 55914PC Black 70Silicone, VMQ SIL 714177 Red 70FluorocarbonFKM, Viton ® AFPM 51414 Black 75FPM 51414G Green 75Viton ® GF FPM 514141 Black 75Perfluoroelastomer,FFKMFFKMFFKMFFKM-75-162FFKM-75-164Black 75Black 75Temperature–35 to +110°C–31 to +230°F–55 to +130°C–67 to +266°F–50 to +150°C–58 to +302°F–55 to +230°C–67 to +446°F–20 to +200°C–4 to +392°F–20 to +200°C-4 to +392°F–10 to +200°C+14 +392°F+275°C+527°F+310°C+590°FO-rings are available in the compounds detailed in the table on pages 14-15.ApplicationStandard compound with good compression-set valuesand medium acrylonitrile content for use with hydraulicoils, vegetable oils, animal fats, acetylene, alcohols, water,air, fuels and many other fluids.Standard, sulphur cured EPDM compound with very goodcompression-set for use with solvents, alcohols, ketones,esters, organic and inorganic acids.
