Silver-Plated OFHC Copper Gaskets for ConFlat® (CF) UHV Flanges

We offer a full range of gaskets for CF flanges to meet your application requirements. 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.

Notes:

Silver & Gold plated Copper – Produced from our ¼ hard, high purity, OFHC copper gaskets. Silver or Gold plated gaskets are ideal for systems requiring frequent high-temperature bakeouts. Maximum Bakeout Temperature is 450° C.
For detailed information about the advantages of the various materials used to make gaskets, see the Technical Information Section regarding Gaskets.
KJLC flanges & gaskets are compatible with flanges produced to the ISO3669-2017 & ASTM E2734/E2734M-10 standards.
All metal gaskets are individually packaged.
