Hardness influences flexibility, assembly and mechanical behavior. The listed options are 80A, 85A and 95A. Confirm operating pressure for the specific model.
TPU TPU Polyurethane Tubing for Liquid Handling, 1.6–7.0 mm ID, 80A/85A/95A
TPU (thermoplastic polyurethane) tubing, also called PU tubing, offers abrasion resistance and good elastic recovery. It is suitable for instrument gas lines, pneumatic component connections and connections to moving parts where flexible routing is needed. For liquid transfer, confirm fluid compatibility with the specific material grade.
Inner diameters range from 1.6–7.0 mm and outer diameters from 3.2–10 mm. Hardness options are 80A, 85A and 95A, with natural, red and blue colors available in model-specific combinations. Tubing is available by the roll. Fittings must be matched to tubing dimensions, tolerances, hardness and connection design. Include any cut-to-length or preassembled tubing requirements in your quotation request.
FOREACH holds ISO 9001 and ISO 13485 quality management system certifications and supports sample testing. The availability of compliance documentation, including RoHS reports, is confirmed for the selected model and project requirements. TPU hydrolysis resistance depends on the material type. For prolonged contact with water or wash fluids, check the specific grade, temperature and contact time. For connections to moving parts, also review bend radius, movement frequency and how the ends are secured.
Typical Applications:
Instrument gas lines and pneumatic connections, Flexible routing for moving parts, Low-pressure liquid lines after fluid compatibility has been confirmed
