General description

Swage type fittings are one of the most popular connectors which are available in metal and plastic forms; they are very useful for connecting similar or dissimilar materials, like metal to glass or metal to plastic. The general swage tubing coupler has four parts namely the body, into which the tube is placed, two ferrules that is front ferrule and back ferrule and lastly a packing nut. If one is using the original nut supplied for the injector and non-MS detector end of an GC instrument, one should choose a Supeltex^® short design ferrule. Supeltex^® M-4 (flexible graphite) ferrules provide great sealability, ensuring a leaktight seal for extended periods at high temperature. It has limited reusability.

Supelco has refined the design of these graphite ferrules to provide a clean, sharp profile with minimal flash.Characteristics: Seals at one-quarter turn past fingertight. Maximum sealing surface contact, reduced risk of column contamination at installation.Material Composition: flexible graphiteMaximum Temperature: 450 °C
