Compact 9 mm Tube/Hose Straightener — quickly corrects bends and kinks in brake lines, fuel lines, A/C refrigerant lines and copper tubing Key benefits Prevents flow restrictions: quickly straightens kinks and bends to restore proper alignment and promote optimal fluid or refrigerant flow. Saves time and effort: portable, easy-to-use tool designed for fast on-vehicle or workshop repairs without cutting or replacing tubing. Built to last: durable materials and precise construction provide reliable performance for repeated professional or DIY use. What it does and why you need it Corrects bends and coils in 9 mm hoses and tubes so systems run efficiently and reliably. Properly aligned lines reduce the risk of pressure loss, poor braking feel, fuel delivery issues, or HVAC performance problems. Ideal when space is limited: the ergonomic shape and compact size let you work in tight engine bays, undercarriages, or HVAC cabinets with better control and less strain. Key features Size: designed for 9 mm hoses/tubing. Construction: inner rolling shaft made from aluminum alloy for smooth rolling action; four ABS plastic outer segments for robust guidance and protection of the tube surface. Materials: combination of high-quality PVC components and aluminum for long-lasting durability and stable performance. Ergonomic design: shaped for a secure grip and comfortable handling during repetitive use; works well for both professionals and home mechanics. Compatible applications (examples) Brake line maintenance: straighten small bends or kinks during brake line routing or repair to maintain correct fluid flow. Fuel system work: align fuel lines during installation or service to prevent restrictions and ensure consistent fuel delivery. Automotive HVAC and refrigeration lines: correct bends in A/C refrigerant lines during servicing or retrofits to maintain system efficiency. Copper tubing tasks: suitable for delicate straightening of small-diameter copper tubing in automotive and light plumbing applications. How to use (overview) Position the tube between the roller and guides, then roll the tool along the bent section while applying light pressure to reshape the tube to the correct alignment. Designed for quick, controlled correction without damaging the tube surface. Who it’s for Automotive technicians, HVAC technicians, and home mechanics who need a compact, reliable tool for straightening 9 mm hoses and small tubing during installation and repair. Specifications Intended tube diameter: 9 mm Inner roller: aluminum alloy Outer parts: ABS plastic (4 segments) Body materials: PVC and aluminum components Durable, portable, and straightforward — a practical addition to any toolkit for improving flow and alignment in brake, fuel, A/C and small copper tubing applications.
