O-Ring, Perfluoro, #108, each

O-Ring, Perfluoro, #108. One of the most thermally stable elastomeric materials available, Perfluoro is a family of perfluoroelastomer compounds designed to provide superior chemical resistance, and they offer a cost savings over similar O-rings such as Kalrez 4079 and Chemraz. Perfluoro O-rings are stocked in WHITE 75 durometer (unless otherwise noted). The effective service temperature is -7 to 230 degrees C. Recommended for use with acids, inorganic bases, alcohols/ethers, aromatic hydro-carbons, esters, aldehydes/ ketones, aliphatic hydrocarbons, amines and chlorocarbon solvents. For complete chemical resistance and fluid compatibility, see chart in the front of this catalog. NOTE: FOR PERFLUORO O-RINGS USED WITH DURAN FLANGES, SEE CG-147. Made in the United States.
