Specify flanging at one or both ends, and define the fitting material, thread and connection type for A/B separately. For a single-flanged assembly, specify the other end connection on the drawing.

Flanged Tubing Assemblies
FOREACH supplies single- and double-flanged tubing assemblies for flat-bottom fluid ports in in-vitro diagnostic and automated analytical instruments. The flanged tube end, matching fitting and washer form a face seal. Equipment development, assembly to drawing and batch production are supported.
Select FEP, PTFE or PFA tubing to suit the flanging process and mating port. PPS, PVDF and PEEK fittings are available in standard and compact structures, with M6×1 and 1/4-28 UNF threads; selected miniature configurations support 6-40 UNF. 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 specified ID/OD pairs. SUS, PEEK or PTFE washers are selected by model. Length, A/B fittings, coils, protective sleeves, stop tubes and identification can be specified.
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 lists fitting series, threads and body materials for 1.6 mm tube OD as examples. Select the drawing by material and full model number; confirm matching parts for other ODs during customization.
