Filcoflex polyurethane (PU) hose on a roll is a smart and practical solution for industries working with bulk powders. It’s perfect for quickly connecting pipes or machine parts, especially during testing, repairs, or when waiting for permanent parts to arrive. Made from thermoplastic polyurethane, the hose is created without glue, using only high-frequency heat to form a strong, seamless tube. It meets stringent compliance standards including EG 1935/2004, FDA, and ATEX zones 20, 21, and 22, making it safe to use in sensitive areas, including places where explosive dust might be present.
The PU material has many benefits that make it ideal for industrial use. It’s flexible but tough, so it won’t tear easily—even when bent, stretched, or exposed to rough conditions. It handles oils, moisture, and chemicals better than many other materials, and its smooth inside surface helps powders flow easily without sticking. Because the hose is made from a single piece of polyurethane sheet, there are no weak points, giving it a longer life and making it more reliable in tough working environments.
PU hose on roll comes in three thicknesses—0.3mm, 1.0mm, and 1.5mm—on rolls up to 1500mm long. It is easy to cut to the size you need and simple to attach using KLB20 hose clamps. The hose can stretch slightly to fit different pipe sizes and works with both round and oval tubing. It’s a great item to keep in stock for quick fixes, temporary setups, or test runs. Because it takes up little space and is so easy to use, it is essential for any factory that handles powders.
