304 Stainless Steel KF40 (KF40) Vacuum Hinged Clamps, NW Falnges Heavy Chain Clamp with fastener nut, For NW40 Conversion Centering Rings (NW40)

FeaturesThe most frequently used clamping component for elastomer seals is the KF clamping ring, consisting of two die-cast aluminum shells and special individual parts made of galvanized steel. A large wing screw is used to achieve the necessary contact force.Clamp chain as an ISO-KF connection element: securely connects flanges in vacuum applications with a tight seal. Suitable for centering rings and metal seals. These seal components allow the installation of vacuum attachments for the pressure range of 2500 mbar (4000 mbar in conjunction with an outer retaining ring and a solid tension clip) to 10–9mbar.Hinged ClampsHinged KF Clamps feature special centering ribs and evenly distributed damping force to assure uniform O-ring compression. Additional hinge knuckles and tighter manufacturing tolerances result in precise alignment and reduced side play. Clamp opening is limited to facilitate one-handed installation in hard-to-reach spaces. Specifications for ISO-KF 16 through 50 flanges.SpecificationsSize: NW(KF)16 to NW(KF)50Material: 304SSVacuum Range: 760 Torr ~ 1×10-8 TorrPackage Included:1* KF40 KF Chain Clamps
