Made from durable PE plastic and color-coded for fast size recognition, each 4-meter strip lets you shape runs, make compact elbows, or repair existing lines while keeping internal flow intact.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these bending strips prevent kinks during pipe bending?\u003c\/h3\u003e\n\u003cp\u003eInserted into the copper tube before bending, the PE strips support the tube wall and distribute bending stresses evenly, which reduces the chance of sharp creases that restrict refrigerant flow.
