Each spring is made from high-carbon spring steel with a rust-resistant finish and a long 43-inch length to offer extra leverage and reach in cramped areas. The kit is designed to handle copper, aluminum and thin-wall steel tubing and includes sizes that cover the most common residential and light-commercial applications.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tool prevent kinks when bending copper tube?\u003c\/h3\u003e\n\u003cp\u003eThe spring wraps around the tube and supports the wall during bending, distributing pressure evenly so the tube keeps its round shape and internal diameter. This prevents the flattening and crimping that cause restricted flow or leaks when tubing is bent without support.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal support from full-length spring prevents wall collapse.\u003c\/li\u003e\n  \u003cli\u003eSix size-specific springs match tube diameters for even compression.\u003c\/li\u003e\n  \u003cli\u003eLong 43\" springs reduce hand force needed, lowering deformation risk.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich tube sizes are included and what materials can I bend?\u003c\/h3\u003e\n\u003cp\u003eThe set contains six springs sized for 1\/4\", 5\/16\", 3\/8\", 1\/2\", 5\/8\" and 3\/4\" tubing, covering common HVAC and plumbing diameters.
