Bored Flanges

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). Flanges align with a centering ring (sold separately) and o-ring seal and must be tightly clamped.  Clamps are sold separately. 304L stainless steel flanges are ideal for systems with extreme temperatures and corrosive environments.  KF (QF) Flanges are also available in Aluminum or Brass for general applications.
