No. The matching fitting compresses the ferrule to retain and seal the tubing. Follow the model-specific requirements for ferrule orientation, tube insertion depth and tightening.
Ferrule Tubing Assemblies
FOREACH ferrule tubing assemblies combine matching fittings, ferrules and tubing for fluid connections in in-vitro diagnostic and automated analytical instruments. No pre-flanging is required: the fitting compresses the ferrule to retain and seal the tubing. Equipment development, assembly to drawing and batch production are supported.
Select FEP, PTFE or PFA tubing matched to the ferrule structure. Depending on the series, fittings are available in PPS, PVDF, PEEK, POM or PP; ferrules are available in PP or ETFE. Standard and compact structures fit M6×1 or 1/4-28 UNF flat-bottom ports. Tube OD options are 1.6, 2.0, 2.5, 3.0 and 3.2 mm, with FEP IDs spanning 0.3–2.0 mm in listed pairs. Specify length, A/B connections, coils, protective sleeves, stop tubes and identification. Match ferrules to tube OD and assemble in the specified orientation and at the specified torque.
FOREACH holds ISO 9001 and ISO 13485 quality management system certifications.
Typical Applications:
