PFA Ferrule Tubing Assembly
FOREACH PFA ferrule tubing assemblies combine PFA tubing, matching fittings and ferrules. The compressed ferrule connects the instrument port without pre-flanging the tube end. They can connect reagent, cleaning-fluid and internal fluid paths in in-vitro diagnostic (IVD) and automated analytical instruments. Reference tubing OD is 1.6 mm, with IDs of 0.5, 0.8 or 1.0 mm. Specify length and both end connections in the drawing.
Standard flat-bottom port threads include M6×1 and 1/4-28 UNF. Select fitting materials and PP or ETFE ferrules for the model, tube size and operating conditions, confirming compatibility among tubing, ferrule and port. Define A/B fitting structures, threads and materials separately and specify stop tubes and identification as needed. 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:
PFA reagent line connections, End connections for 1.6 mm OD tubing, Fluid connections without pre-flanging, Instrument tubing assembly

PFA 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.
PFA tubing and custom ends
PFA tubing can be configured for the required length and end connections. Confirm tube-end forming and sealing components against the selected size and mating port.
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.
