Manufactured for use in vacuum piping systems, CF flanges are fabricated to ASTM E2734 Standard Specification and incorporate a mechanical seal to create a leak-tight connection between flanges. When the bolts squeeze the flanges together, the soft metal gasket melds into a thin groove cut into the flat flange surface which provides the leak-tight seal. Flanges operate in temperature from -196°C through 450°C and pressures from 760 Torr (103mbar) to less than 1 x 10-12 Torr (1 x 10-12 mbar)....

Manufactured using 304L stainless steel, KF flanges, commonly known by International standards Organization as Klein Flansche (KF) fittings, are used in vacuum piping and high vacuum chambers (10-8 Torr). The 304L stainless steel material makes the flanges ideal for systems with extreme temperatures and corrosive environments. Flanges operate in temperature from 0°C through 180°C and pressures from 760 Torr (103mbar) to less than 1 x 10-8 Torr (1 x 10-8 mbar). Generally, KF (QF) flanges are...
