    • Constructed with an inner TPU lining and a reinforced outer layer, typically made of braided fabric or wire.
    • Provide enhanced pressure and burst resistance, making them suitable for high-pressure applications.
    • Offer improved kink resistance and dimensional stability compared to non-reinforced TPU hoses.
    • Commonly used in hydraulic systems, pneumatic equipment, and other industrial applications requiring high-pressure tolerance.

    Non-Reinforced TPU Hoses:

    • Consist of a single layer of TPU material without any additional reinforcement.
    • Offer excellent flexibility, conformability, and ease of installation, making them suitable for applications with lower pressure requirements.
    • Commonly used in applications such as material handling, food and beverage transfer, and low-pressure pneumatic systems.

    Conductive/Anti-Static TPU Hoses:

    • Designed with the ability to dissipate static electricity and prevent the buildup of static charges.
    • Incorporate conductive fillers or additives within the TPU material to provide static-dissipative properties.
    • Useful in applications where the risk of static electricity discharge is a concern, such as in the chemical, petrochemical, and electronics industries.

    FDA/Food-Grade TPU Hoses:

    • Manufactured to meet FDA (Food and Drug Administration) and other food-grade regulations and standards.
    • Formulated with TPU materials that are safe for contact with food, beverages, and pharmaceutical products.
    • Commonly used in the food and beverage processing, pharmaceutical, and biotechnology industries.

    TPU Layflat Hoses:

    Designed to collapse and lay flat when not in use, reducing storage space requirements.

    Constructed with a TPU inner lining and a reinforced outer layer, often with a woven fabric or mesh.

    Offer flexibility and conformability, allowing the hose to easily navigate around obstacles and through tight spaces.

    Commonly used in applications where portability, space-saving, and ease of handling are important, such as:

    • Irrigation and agricultural water transfer
    • Temporary water supply lines
    • Emergency response and disaster relief operations
    • Construction site dewatering

      The layflat design enables the hose to be easily transported, deployed, and stored when not in use, enhancing overall efficiency and convenience.

      Specialty TPU Hoses:

      Designed for specific applications or environments, such as:

      • UV-resistant TPU hoses for outdoor use in agricultural or construction applications.
      • Low-temperature TPU hoses for use in cold environments.
      • Hoses with enhanced chemical resistance for exposure to aggressive substances.

        These specialized TPU hoses are tailored to meet the unique requirements of the application.

        When selecting the appropriate TPU hose type, it is crucial to consider factors such as pressure, temperature, chemical exposure, regulatory compliance, and the specific demands of your application. Consulting with a knowledgeable TPU hose manufacturer or supplier can help you identify the optimal hose solution for your needs.
