SilTite™ metal ferrules have been developed specifically for use with GC/MS systems and have distinct advantages over graphite and composite ferrules for use with GC/MS interfaces. The metal SilTite™ ferrule and nut are made from the same material and therefore have the same thermal expansion coefficient. As the oven heats up and cools down, the nuts and ferrules expand and contract at the same rate, eliminating annoying leaks and the need to retighten the ferrule after installation. SilTite™ nuts are reusable.
