This 150PSI EPDM collapsible drainage hose is integrally molded from EPDM rubber. Its highly flexible material allows it to be completely rolled up and flattened, taking up minimal storage space. The smooth inner wall ensures unobstructed drainage and prevents the accumulation of impurities. With a pressure rating of 150PSI, it meets the requirements of standard drainage operations. It is highly resistant to sunlight, ozone, and acid/alkali sewage corrosion. It remains flexible in low temperatures and resists cracking and aging during long-term outdoor use. Lightweight and easy to drag and lay out, it is perfectly suited for scenarios such as temporary drainage at construction sites, garden irrigation, municipal floodwater pumping, and wastewater diversion from equipment.
