For liquid lubricating oil lines, send your requirements for review. - **Dimensions:** use the model table below, including ID, OD and **bend radius** where supplied. - **Order details:** provide the model, quantity, length, color and destination. ### Confirm these conditions before use The listed pressure and temperature values are not a combined operating envelope. Burst pressure must not be used as a working-pressure rating. Confirm temperature-related pressure limits, fitting requirements and any movement or external exposure before selecting a model. No food-contact, medical, brake-line or universal chemical compatibility approval is established by this page. ### Comparing PU with nylon? Review the [PU vs. nylon selection checklist]() , then compare the exact [PA6]() or [PA12]() model. A material family alone does not determine a safe operating limit. ### Polyurethane pneumatic tubing: choose the complete size **PU tubing** sizes must identify both outside diameter (OD) and inside diameter (ID). For 6 mm or 8 mm OD tubing, select the corresponding ID and model from the table rather than ordering by OD alone. Our [pneumatic tubing size guide]() explains the measurements. ### Choosing a PU tubing manufacturer When comparing **polyurethane tubing** manufacturers, ask for the exact material designation, model dimensions, supply length and pressure conditions. Send YUANNAI TUBE your model, quantity, color and destination to discuss the available range.

Model designations and table values below follow the 2026 technical data sheet for this product. Dimensions and pressure tables are specified at 23°C. Pressure values are in bar (psi) as stated in the data sheet. **Working pressure** is the design rating and burst pressure is a test value; pressure and temperature ratings are listed separately, so send your operating point for a combined-condition check. Tolerance, metric/inch size system and, where applicable, layer construction are identified in each row. Physical properties are reference values from the data sheet; test methods and application-specific compliance are reviewed against your requirements.

State the **inner diameter**, **outer diameter** and units, then compare the model table with the fitting requirements. Include length, quantity, pressure, temperature and the actual medium in your **inquiry**. Operating ratings are set per model. Can I use the listed PU pressure value at any temperature? Do not treat a source value as an unconditional rating. Confirm the selected model, working temperature, medium and test conditions before using it in your design. What should I provide for a PU tubing quotation? Send the model or dimensions, color, quantity, fittings and actual air-line conditions. Include a drawing or existing specification when available. What are the specifications of PU tubing? The 15 listed models cover metric sizes from 2.5 x 4 mm to 12 x 16 mm and inch sizes from 1/8" to 3/4", supplied in 100 m or 200 m rolls with a tolerance of ±0.10 mm. The supplied data sheet lists a hardness of 98 ± 2 Shore A and an **operating temperature** range of -20°C to +55°C. **Working pressure** is model-specific and listed in the specifications table, so read the row for your exact size. Can polyurethane tubing be used for fuel lines? The supplied data sheet scopes this PU range to compressed air, inert gases and vacuum circuits, and it does not recommend continuous long-term transfer of large quantities of liquid lubricating oil. Fuel is outside the listed scope. Send the medium, temperature and pressure and we will review it against the data sheet. What colors does PU tubing come in? The transparent range is clear, transparent blue and transparent red. The solid range is orange, dark blue, sky blue, black, green and yellow. Customer brand logos, model identification and continuous meter markings can be customized. Confirm color, marking and order quantity when you **request a quote**. Is polyurethane tubing a plastic or a rubber? **Polyurethane tubing** is generally made from thermoplastic polyurethane (TPU), a flexible elastomer that is extruded like a plastic and bends like a soft rubber. Hardness and flexibility vary by grade, so check the Shore hardness and **bend radius** for your model on the supplied data sheet. ## Let’s Discuss Your Tubing Requirements.
