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 Ferrule Tubing Assembly
FOREACH FEP ferrule tubing assemblies combine transparent FEP tubing, matched threaded fittings and ferrules without pre-flanging the tube end. They 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 the actual ID/OD pairs and specify finished length and A/B end connections.
The fitting compresses the ferrule to retain and seal tubing at M6×1 or 1/4-28 UNF flat-bottom ports. Depending on the series, PPS, PVDF, PEEK, POM and PP fittings are available in standard and compact structures, with PP or ETFE ferrules matched to tube OD and port. Coils, protective sleeves, stop tubes and identification can be added to the installation drawing. Equipment development, samples 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 line connections, Cleaning-fluid line connections, End connections without pre-flanging, Internal instrument fluid-path assembly
