Description
We manufacture a full range of OFHC Copper, annealed copper, aluminum and
gold and silver plated copper gasket, 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 for high vacuum
and UHV applications. Many gauges, instruments, accessories and feedthroughs
are available on this flange system.
CF Gasket Materials:
* 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.
* Silver & Gold plated Copper -- For systems requiring frequent high
temperature bakeouts, silver or gold plated copper gaskets are
recommended.
* Aluminum (1100-H14) -- Aluminum CF flanges must use aluminum
gaskets 鈥攏ever copper. However, aluminum gaskets can be used on
stainless steel CF flanges if baking is restricted to 200掳 C.
* Fluorocarbon -- Fluorocarbon gaskets, with a flat cross-section, are
convenient and reusable in non-critical, non-UHV applications, particularly
in applications requiring frequent reassembly.
* Nickel gaskets are typically used in applications with a corrosive environment.
Note:
*Our proprietary deburring and polishing processes, designed specifically
for vacuum applications, make us one of the largest copper gasket
producers in the vacuum industry.
*For detailed information about the advantages of the various materials
used to make gaskets, see the Technical Information Section regarding
Gaskets.
All OFHC Copper, Silver- plated and Annealed gaskets are individually
packaged.
