Product Description

CF Bored Blank Flange Tapped
The CF flange connection consists of two identical flanges with a flat gasket made of OFHC copper, bolts, nuts. Because the applications are UHV environments, so the preparation work is very important before installation. Surface cleaning guarantees the lowest possible outgassing and leak rates.
Offered in both rotatable and nonrotatable versions with through holes and tapped bolt holes. Metric tapped holes and
untapped holes flanges are identical products. UNC or UNF or other tapped holes can be ordered as specials.CF flanges are suited for use in applications requiring a very clean environment, ultrahigh vacuum conditions,a high temperature or where critical or dangerous materials must be contained or excluded.
