The Fittings | Spring Clamp w/ Screw & Wing Nut (KF16) is a heavy-duty large-diameter spring clamp designed to secure glass-to-glass and glass-to-metal connections on wiped-film and short-path distillation equipment. The spring-loaded mechanism maintains consistent clamping force across thermal cycles, preventing leaks during high-temperature distillation runs. Compatible with VTA and UIC evaporator bodies, cold traps, and receiving flask assemblies that use the corresponding large-diameter joint size. Stainless steel construction ensures corrosion resistance in solvent-rich processing environments.
