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. 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

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.
Black PTFE Flanged Tubing Applications & Customization
Equipment development, assembly to drawing, sample development and batch production are supported.
Instrument fluid-path integration
Assemblies for in-vitro diagnostic and automated analytical instruments are selected against the actual reagent, cleaning fluid and connection requirements.
Black PTFE and light shielding
For instrument fluid paths with light-shielding requirements. Provide reagent-sensitive wavelengths, shielding criteria and installation conditions to evaluate the tubing and complete connections.
Assembly drawings and dimensions
Provide tube ID/OD, finished length and tolerance, length measurement datum, A/B port drawings, fitting materials, threads and installation space. Show stop and label positions and dimensions on the assembly drawing.
Fluids, pressure and temperature
Specify the working fluid, concentration, cleaning fluid, contact time, pressure, temperature and inspection requirements to confirm wetted materials and the complete assembly.
Installation and mating ports
Check the flange face, washer orientation and port sealing face. Even when threads match, verify port depth and flange dimensions.
Quality documents and delivery
FOREACH holds ISO 9001 and ISO 13485 quality management system certifications. Applicable REACH and RoHS reports and material safety data sheets (MSDS) can be supplied for relevant connection components according to material and model. Dimensional inspection, seal testing, identification and packaging requirements for samples and batches are agreed for each project.
