PTFE Ferrule Tubing Assembly
FOREACH PTFE ferrule tubing assemblies use natural PTFE tubing with matching fittings and ferrules to connect flat-bottom ports without pre-flanging. They are configured for reagent and cleaning-fluid lines in in-vitro diagnostic (IVD) and automated analytical instruments. Available tubing IDs span 0.5–2.0 mm, with ODs of 1.6, 2.0, 2.5, 3.0 and 3.2 mm in specified pairs. Specify finished length and the layout of both end connections.
Threads include M6×1 and 1/4-28 UNF. Fittings are available in PPS, PVDF, PEEK, POM and PP by series; PP or ETFE ferrules must match tube OD and port geometry. Select wetted materials against working and cleaning fluids and define each A/B fitting and thread separately. Stop tubes and labels can follow the installation drawing. 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:
PTFE reagent line connections, Cleaning-fluid line integration, Connections without pre-flanging, Instrument port assembly

PTFE Ferrule 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.
PTFE tubing and custom length
Natural PTFE tubing is cut and fitted to the instrument fluid-path layout. Provide the working fluid, cleaning fluid and operating temperature for material selection.
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 ferrule orientation, tube insertion depth and fitting tightening requirements. Assemble to the drawing and specified torque; avoid tension and sharp bends.
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.
