[Request a Quote]() [Download PDF]() [Review specifications ↓]() PRODUCT OVERVIEW ## Product overview Flexible **composite tubing** in this range is identified by its model code and tube dimensions. Use the supplied **high-pressure composite tubing** data to review the intended medium, layer construction and fittings; confirm the selected model’s working-pressure conditions. ### Key features - #### Virgin material Extruded from selected virgin material (data sheets V8 and V9). - #### Two-layer co-extrusion Outer layer for abrasion resistance and flexibility, PA12 inner layer for low permeability and pressure stability. V8: PU outer layer. V9: polyether TPU outer layer. - #### Colors and marking Milky white, black, blue and orange; custom colors available. Brand logos, model identification and continuous meter markings can be customized. - #### Temperature range V8: -20°C to +55°C; V9: -30°C to +60°C - #### Working pressure 12 bar (185 psi) – 19 bar (276 psi) at 23°C, depending on the model (data sheet). Burst pressure is not **working pressure**. - #### Sizes 28 listed models, outside diameter 3.2–19.1 mm. Inch sizes are listed where the data sheet gives them. ![Tubing extrusion and coiling line in the Hefei factory]() ### How the tubing is made and checked Tubing is produced on extrusion and coiling lines and checked with dimensional, pressure-hold, burst-pressure and tensile equipment listed in the company inventory. Product requirements are reviewed against the drawing and order. 1. **Incoming**Check supplier documents, material identity, specification, quantity and packaging. 2. **In process**Drawing and route-sheet revision checks, measurement-equipment status and **inspection records**. 3. **Finished tubing**Identity, surface and tube-end condition, dimensions, marking, cleanliness and packaging.

It is the product-family name in the supplied technical data sheets. Use confirmed model-specific pressure and temperature conditions; the name alone does not define a rating. Which details identify a flexible composite tubing model? Provide the model code, tube ID and OD, layer construction, material designation, fitting interface and intended medium. Confirm **working pressure** with its temperature and test conditions for the complete assembly. Ratings are set per model; this family is flexible **composite tubing**, not a carbon-fiber structural tube. What fitting details are needed for composite tubing review? Specify the connection design, dimensions, assembly method and operating conditions. Confirm the complete tube-and-fitting arrangement before ordering. ## Let’s Discuss Your Tubing Requirements.
