The Vevor mini split line set is designed for mini-split air conditioner and heat pump installations where a reliable 25-foot refrigerant line run is needed. It features 99.9% pure C12200 copper tubing with thick-wall construction for strength, leak resistance, and flexible routing through walls or tight spaces. The insulated PE and EVA outer layer helps reduce energy loss and condensation during operation. A complete accessory kit is included for easier installation, making it suitable for replacement, extension, or new DIY and professional setups.
