This thermoplastic rubber hose is seriously tough stuff for industrial and workshop use! With a 6-inch inner diameter and 12.5-foot length when fully stretched, it's perfect for moving air, dust, abrasives, and various materials. The spring steel wire helix reinforcement gives it great crush resistance while maintaining flexibility - it bends to a 5.5-inch radius without kinking. The yellow wear strip on the exterior adds extra abrasion resistance for when you're dragging it across rough surfaces. What's really impressive is how versatile this hose is - it handles temperature extremes, moisture, UV exposure, and even many chemicals without degrading. The smooth interior means minimal airflow resistance, which is huge for dust collection systems or ventilation. Working pressure is 5 PSI positive and it can handle 8 inches of mercury negative pressure. We use these in our woodshop for dust collection and they've held up way better than cheaper options. If you need a reliable, general-purpose hose that can take some abuse while maintaining good airflow, this thermoplastic flex hose is definitely worth the investment. It's one of those workhorse products that just keeps performing year after year.
