1pc 304 Stainless Steel KF Chain Clamps for NW40 Flanges - Vacuum Fasteners(NW50)

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 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\u20139mbar.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* KF Chain Clamps

• Constructed from durable 304 stainless steel, these KF chain clamps provide exceptional strength and erosion resistance for reliable vacuum applications.
• devised for NW40 KF flanges, these clamps convert elastomer rubber seals to vacuum metal seals, ensuring a tight and secure connection.
• Hinged devise features special centering ribs and evenly distributed damping force for uniform O-ring compression, enhancing sealing efficiency.
• Compatible with ISO-KF 16 to 50 flanges, these clamps are ideal for various vacuum plumbing setups, supporting a pressure range from 760 Torr to 1×10⁻⁸ Torr.
• Easy one-handed installation in hard-to-reach spaces, thanks to the limited clamp opening, making it a practical choice for professionals in vacuum technology.
