However,sustained baking above 302°F (150°C) may result indeterioration of the O-ring.■ Vacuum Range: ≥ 10 –8 Torr■ Operational Temperature Range:Fluorocarbon FKM O-rings: –4 to 392°F (–20 to 200°C)Silicone O-rings: –58 to 446°F (–50 to 230°C)Buna O-rings: –22 to 230°F (–30 to 110°C)Applications■ Roughing lines■ Vacuum systems requiring frequent disassembly forcleaning or modification■ Experimental systems found in research laboratoriesFlange DimensionsDimensions, in inches (millimeters), are for reference only andare subject to change.FlangeSizein.A BTubeODin.Dimensions, in.
