VEVOR 25FT Mini Split Line Set, 3/8" & 5/8" O.D Copper Pipes Tubing And Triple-Layer Insulation, For Mini Split Air Conditioning Refrigerant Or Heating Pump Equipment & HVAC With Wrapping Strips.

VEVOR Mini Split Line Set We use high-quality copper tubes that comply with ASTM standards, offering excellent toughness and hardness. The three-layer insulation cotton provides effective insulation, specifically designed for mini-split air conditioning systems. Utilizing pure copper pipes, our products offer flexibility, allowing bending and straightening without breaking. They resist pulling and bending, with sufficient length to connect indoor and outdoor units. Even when encountering corners that require bending, piping is easily managed. The refrigeration copper tube contains high-pressure and low-pressure tubes, designed specifically for mini-split air conditioning systems used in homes, offices, malls, restaurants, and similar spaces. We strictly control the materials used, rejecting inferior ones. We use high-hardness thickened brass nuts, fluoroelastomer-coated smooth flare mouths, and protective covers to prevent dust from entering the copper tubes. To better protect the internal copper tubes, unlike ordinary double-layer insulation materials, VEVOR employs three-layer insulation materials for superior insulation performance. The embossed surface treatment enhances durability, showcasing undeniable strength.
