Self Tightening Column Nuts

Self Tightening Column Nuts

This unique, stainless steel GC column nut delivers a tight connection – without expensive upgrades or adaptors. An innovative spring-driven piston continuously presses against the short graphite/polyimide ferrule – maintaining a leak-free seal even after hundreds of injection. It is especially well suited for oxygen sensitive detectors, such as mass spec and ECD. Tight column connections provide reduced background noise, reliable results, and saved time, due to not needing to retighten fittings.
