Rubber Viton O Ring   Viton (FKM) O Rings have a low compression set and have high temperature and chemical resistance. More expensive than NBR O Rings. The terms FPM, FKM and Viton very often cause confusion and lead to incorrect interpretations. All of these designations actually stand for one single base material: fluoro rubber.Temperature Range -30°C to +200°C (avoid prolonged use at higher extremes)

  Rubber EPDM O Ring Excellent resistance to weathering and ozone, water and steam, with good performance in castor and some phosphate ester based fluids. Its low and high temperature capability is good, having excellent resistance to set with good resilience. Also high temperature braking systems employing castor based fluids for mouldings subjected to weathering and ozone and for seals in chemical plant due to its good chemical resistance. EPDM is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol or silicone base. This results in a highly fluorinated elastomeric compound with exceptional temperature resistance, compatibility with a wide range of aggressive chemical combinations and outstanding resistance to permanent deformation.
