Transparent FEP tubing allows visual observation of liquid and bubbles. Visibility depends on the tube wall, ID and liquid colour; check a sample with the actual liquid.
FEP Flanged Tubing Assembly
FOREACH FEP flanged tubing assemblies combine transparent FEP tubing, matching threaded fittings and support washers. Single- and double-flanged configurations connect reagent, cleaning-fluid and internal fluid paths in in-vitro diagnostic (IVD) and automated analytical instruments. Available tubing IDs span 0.3–2.0 mm, with ODs of 1.6, 2.0, 2.5, 3.0 and 3.2 mm. Select ID and OD as specified pairs. Equipment development, assembly to drawing and batch production are supported.
The flanged tube end and matching washer form a face seal at a flat-bottom port. PPS, PVDF and PEEK fittings are available in standard and compact structures, with M6×1 or 1/4-28 UNF threads. Specify finished length, single- or double-flanged ends and each A/B fitting material, thread and connection type in the assembly drawing. Coils, protective sleeves, stop tubes and identification can be added for the installation space and routing. Confirm working pressure and temperature for the specific dimensions, ports and complete assembly.
FOREACH holds ISO 9001 and ISO 13485 quality management system certifications.
Typical Applications:
Reagent line connections, Cleaning-fluid line connections, Internal instrument fluid connections, Custom fluid-path assembly

These are available tubing sizes. Confirm flange dimensions and mating ports against the assembly drawing.
Match fitting material, structure and thread to the corresponding model.
Miniature option: 6-40 UNF, PEEK fitting, 1.6 mm tube OD. Confirm the complete end configuration against the selected model.
Working pressure and temperature must be confirmed for the specific assembly configuration.
Matching fittings and 2D drawings
The table uses fittings for 1.6 mm tube OD as examples, with material/thread combinations from the current selection data. Drawings identify fitting-body dimensions; for other ODs, select the corresponding model and washer during configuration.
