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.
Use PTFE ferrules instead of brass or stainless steel ferrules when attaching fittings to glass tubing, or to flexible tubing (such as PTFE or Tygon).

Swagelok^® PTFE ferrules maybe used, for making all the connections between glass and PTFE present in the containment vessels, piping, and sampling equipment in a bench scale biofilter system, in an experimental study investigating the effects of periods of non-use on biofilter performance.
