Flangeless tube end fittings
Flangeless tube end fittings utilize our collapsible ferrule, which grips the tubing as the fittings is tightened without significantly reducing the tube ID.

Flanged tube end fittings
Flanged tube end fittings are retained on polymeric tubing by a flange formed with a Cheminert flanging tool.
