When installing or upgrading an HVAC system, exposed refrigerant lines can affect both durability and appearance. The MRCOOL MLG450 provides a complete solution to protect, organize, and conceal line sets while maintaining a clean, professional finish.
Designed for use with ductless mini-split and central HVAC systems, this kit helps shield refrigerant lines from weather exposure, debris, and external damage. The MRCOOL Ductless Mini Split LineGuard Line Set supports up to 12 feet of coverage using three straight sections, along with additional components for routing and sealing. It is suitable for installations where line sets are exposed along exterior walls, helping maintain both system protection and visual consistency.
The kit includes interlocking components that allow for straightforward installation without special tools. A bend piece supports smooth corner transitions, while the wall hole cover helps seal openings for a cleaner finish. Its durable construction is designed to withstand outdoor conditions, helping reduce wear caused by moisture, sunlight, and environmental exposure. The structured design also helps maintain alignment and organization of line sets over time.
By organizing and protecting exposed components, this kit improves both system durability and installation quality. It offers a practical solution for achieving a cleaner, more secure HVAC setup.
