Construction
The insert consists of an external section, or flange, and an internal section with a core and ribs. As with typical push-in tube inserts, the ribs flex during insertion to hold the insert in the tube. The flange covers the edge of the tube and determines the insertion depth.
Push-in inserts of this type are used wherever an open tube end needs to be closed. To install, push the internal section into the tube until the flange rests against its edge. The black colour and smooth flange surface give tube ends a neutral finish.
