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.
We use the CF flange flange type most widely 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.
· We use a copper Gasket to mate two Conflat (CF) vacuum flanges together. These conflat copper conflat gaskets fit a conflat flange size of 2-1/8 inches.
· The gasket material sealing two flanges determines the joint’s maximum temperature. To an extent, the base pressure of the vacuum volume.
· Metal gaskets are impermeable to gases and withstand moderately high temperatures indefinitely.
The normal gaskets for stainless steel CF flnges are punched from 1/4 hard, high purity, oxygen-free (OFHC) copper stock.
· We cleaned and processed the gaskets chemically to minimize scratches and burrs. And used ConFlat (CF) flanges for ultra-high vacuum applications.
These fittings use a copper gasket and knife-edge flanges to achieve the high vacuum seal. And they can operate down to 10-13 torr (10-11 Pa). And they can be heated to 450 °C for bake-out.
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.
