Confirm performance for the reagent-sensitive wavelengths and actual shielding requirements. Black appearance alone does not replace light-shielding validation of the complete fluid path.

Black PTFE Flanged Tubing Assembly
FOREACH black PTFE flanged tubing assemblies combine black PTFE tubing, flanged fittings and support washers for reagent lines with light-shielding requirements in in-vitro diagnostic (IVD) and automated analytical instruments. Reference tubing IDs span 0.8–2.0 mm, with ODs of 1.6, 2.0, 2.5, 3.0 and 3.2 mm in specified pairs. Single- or double-flanged ends, length and both end connections can be specified.
Select PPS, PVDF or PEEK fittings with M6×1 or 1/4-28 UNF threads and standard or compact structures for the port location. Provide reagent-sensitive wavelengths and shielding requirements so the tubing, flanged ends and complete connections can be evaluated together. Protective sleeves, stop tubes and text labels can follow the installation route. Samples to drawing 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.
Typical Applications:
Reagent lines requiring light shielding, Black PTFE fluid connections, Flat-bottom port integration, Instrument tubing assembly

Tube Size Combinations
| Tube OD (mm) | Matching Tube ID (mm) |
|---|---|
| 1.6 | 0.8 |
| 2.0 | 1.0 |
| 2.5 | 1.5 |
| 3.0 | 2.0 |
| 3.2 | 1.6 |
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.
