High Vacuum Copper Gaskets for 4-1/2 in CF63 Flange Conflat Flange
OFHC Copper Gaskets for CF Flanges
We manufacture a full range of OFHC Copper and elastomeric fluorocarbon gaskets for CF flanges.
Metal gaskets are impermeable to gases and withstand moderately high temperatures indefinitely.
The CF flange is the most widely used flange type for high vacuum and UHV applications.
These flanges must be the same outer dimension.
Many gauges, instruments, accessories and feedthroughs are available on this flange system.
CF Flange Gaskets:
•Copper — The normal gaskets for stainless steel CF flanges are punched from 1/4 hard, high purity, oxygen-free (OFHC) copper stock.
The gaskets are then chemically cleaned and processed to minimize scratches and burrs.
•Pressure range: 1 • 10-13 hPa to ambient pressure
•Temperature range: -196 to 200 °C
•For single use only
•CF Flange Size: CF 4-1/2 inch
•Common Dimensions: Flange Outer Diameter (OD) 4-1/2″
