DuctlessAire's 4-piece mini split pipe air line set kit is designed for shaping 1/4 in., 3/8 in., 1/2 in., and 5/8 in. soft copper tubing without the need for bulky tools or springs. With a 4-meter (13-foot) length, this kit simplifies bending refrigerant lines in mini split, air conditioning, and VRF system installations, helping maintain proper tube form. The color-coded mandrels allow quick size selection, improving workflow efficiency for HVAC professionals and technicians. Designed for simultaneous bending of suction and liquid lines, this kit does not require insulation removal, making it a practical addition to any HVAC toolkit. The flexible mandrels support precise bends, helping maintain tube alignment while reducing the risk of deformation. Its lightweight, reusable construction offers a convenient alternative to traditional bending tools, allowing for efficient and controlled tube shaping in tight workspaces. Crafted from durable, flexible material, this kit is built for repeated use in HVAC, air conditioning, and refrigeration projects, ensuring smooth, consistent bends for reliable performance.
