**RECOMMENDED FOR

Buna N

(Nitrile) Widely used elastomer offering excellent resistance to most oils, silicone greases, hydraulic fluids, water and alcohols.
Temperature range: -40º to +250ºF.
COLD WATER
GREASES
OILS
ALCOHOL
PETROLEUM FLUIDS
Neoprene* (Chloroprene) Exhibits moderate resistance to petrolium based fluids. Good resistance to weathering and ozone. Good resiliance low compression set.
Temperature range: -40º to +250ºF.
AMMONIA
MILD ACID
FREON
Silicone Used for wide temperature ranges and dry heat resistance. High resistance to sun and ozone injury. Poor tensile, tear, and abrasion resistance and high friction traits. Is fungus resistant, odorless, tasteless, and toxic.
Temperature range: -75º to +450ºF.
HIGH TEMP
