What Is a Flangeless Ferrule Fitting? Design, Sizes and Selection

Flangeless fittings use a threaded nut to compress a ferrule around rigid tubing, without preforming a flange. FOREACH HN, HN6, HNF and HNF6 cover tubing ODs of 1.6, 2.0, 2.5, 3.0 and 3.2 mm, M6×1 and 1/4-28 UNF threads, and several nut materials for reagent transfer, sample handling and wash lines in analytical instruments and laboratory automation.

Microfluidic Hard-Tube Fitting Selection Guide: Flanged, Ferrule and Snap-Ring Connections

Selection essentials: Check port geometry, tubing OD and fluid first, then pressure, maintenance frequency and tube-end preparation. Flanged fittings press a tube-end flange against a flat sealing face; ferrules grip the tube as the fitting tightens; snap-ring designs use a sleeve and sealing ring. Matching threads and tube diameters alone do not establish compatibility.
