The Fittings | Spring Clamp (KS40) is a heavy-duty KS40 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 KS40 joint size. Stainless steel construction ensures corrosion resistance in solvent-rich processing environments.
