At 2.0 mm OD, natural PTFE offers 1.0 or 1.2 mm ID, giving different wall thicknesses. Select by length, flow and allowable pressure drop; check the size table and end connection.
PTFE Ferrule Tubing Assembly
FOREACH PTFE ferrule tubing assemblies use natural PTFE tubing with matching fittings and ferrules to connect flat-bottom ports without pre-flanging. They are configured for reagent and cleaning-fluid lines in in-vitro diagnostic (IVD) and automated analytical instruments. Available tubing IDs span 0.5–2.0 mm, with ODs of 1.6, 2.0, 2.5, 3.0 and 3.2 mm in specified pairs. Specify finished length and the layout of both end connections.
Threads include M6×1 and 1/4-28 UNF. Fittings are available in PPS, PVDF, PEEK, POM and PP by series; PP or ETFE ferrules must match tube OD and port geometry. Select wetted materials against working and cleaning fluids and define each A/B fitting and thread separately. Coils, protective sleeves, stop tubes and labels can follow the installation drawing. Development samples and batch assembly are supported. Confirm working pressure and temperature for the specific dimensions, ports and complete assembly.
FOREACH holds ISO 9001 and ISO 13485 quality management system certifications.
