WEIR-STYLE DIAPHRAGM VALVE CR NEOPRENE (CHLOROPRENE RUBBER) CSM HYPALON (CHLORINE SULPHONYL POLYETHYLENE RUBBER) EPDM (ETHYLENE PROPYLENE) FPM VITON (FLUORINE RUBBER) IIR (BUTYL RUBBER) A general-purpose elastomer exhibiting a good combination of corrosive and abrasive resistance. Good resistance to many animal and vegetable oils as well as greases and oils in general. Has low vapor and gas permeability making it suitable for gas and vacuum services. Temperature Range: -20 F to 212 F Size Range: .5 to 12 Part Number: 08 Resistant to oils and greases and good general acid

resistance. Temperature Range :0Fto212F Size Range: .5 to 12 Part Number: 01 An excellent general-purpose elastomer for chemical resistance, acid & alkali services, deionized / demineralized and hot water services, intermittent steaming and abrasive applications. Very low vapor and gas permeability. Suitable for High Vacuum, inert gases and many industrial gasses. Temperature Range: -40 F to 260 F Size Range: .5 to 12 Part Number: 14 Hydrocarbon and acid services, particularly sulphur and chlorine based applications. Specific solvents. Not recommended for ammonia, acetone or related

services. Temperature Range :0Fto300F Size Range: .5 to 12 Part Number: 04 Similar to EPDM above. Temperature Range: -20 F to 265 F Size Range: .5 to 12 Part Number: 06 Note: This reference is general in nature. For specific services please consult the factory or your local Gem representative.
