At 2.0 mm OD, natural PTFE offers 1.0 or 1.2 mm ID, giving different wall thicknesses. Select by length, flow and allowable pressure drop; check the size table and end connection.
PTFE Compression-Ring Tubing Assembly
FOREACH PTFE compression-ring tubing assemblies connect natural PTFE tubing to instrument ports using matched compression rings and sealing ferrules. They are configured for reagent and cleaning-fluid lines in in-vitro diagnostic (IVD) and automated analytical equipment. Available tubing IDs span 0.5–2.0 mm, with ODs of 1.6, 2.0, 2.5, 3.0 and 3.2 mm. Specify tube length and end layout using actual ID/OD pairs.
Connections include PEEK 6-40 UNF fittings for 1.6 mm OD tubing and HSF6 fittings with M6×1 or 1/4-28 UNF threads. Select compression rings and sealing ferrules as a set matched to tube dimensions and ports. Define A/B ends separately; coils, protective sleeves, stop tubes and labels are optional. Confirm fluid compatibility using material, concentration, temperature and contact time. 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.

These are available tubing sizes. Confirm end 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.
