Applications
ISA/KF flange clamps are the standard fastening hardware used throughout high-vacuum and rough-vacuum systems to join KF (Klein Flansch) or NW (Nominal Width) quick-flange fittings. They work by compressing a centering ring and O-ring seated between two mating KF flanges, creating a reliable vacuum-tight seal without bolts or tools. This style of clamp is used across vacuum deposition systems, sputter coaters, thermal evaporators, vacuum furnaces, electron microscopes, turbomolecular pump inlets, and general laboratory vacuum lines. Balzers — now part of the Pfeiffer Vacuum group — has been a primary manufacturer of vacuum system components since the mid-twentieth century, and their hardware remains compatible with all standard KF/NW vacuum fittings from any manufacturer. A mixed-size lot like this is particularly useful for vacuum lab maintenance shops, research facilities, and semiconductor fabs that service multiple vacuum line diameters.
This lot of 21 Balzers Pall ISA vacuum flange clamps has been inspected and is in good used condition. The clamps are stainless steel and show normal wear consistent with lab or vacuum system use — minor surface scuffing visible on some pieces. All clamps appear intact with their wing-nut fasteners and hinges present. The lot includes a range of sizes; the largest are approximately 5 inches in diameter.
