Heavy-Duty Copper Tubes with Precision Flaring: Features two pre-insulated, nitrogen-charged copper lines (3/8" low-pressure & 1/4" high-pressure) with a robust 0.024"(0.6mm) wall thickness. Hydraulically expanded flare ends ensure smooth, debris-free connections for superior leak resistance and effortless installation.
Complete All-in-One Installation Kit: Includes everything for a professional setup: 50FT line set with 4 thickened brass flare nuts (high hardness, anti-cracking) ＆ 4 dust plugs, 5 pipe insulation straps, 2 sealing putties, a 50FT drain hose, and a wall sleeve. No extra parts needed—ready to use right out of the box!
Leak-Proof with Dual Protection: Engineered with mechanically flared ends and thickened brass nuts to prevent refrigerant leakage. Each tube undergoes rigorous 12-13kg pressure testing for guaranteed reliability, ensuring your system remains efficient and maintenance-free, withstands extreme temperatures, operates flawlessly from -22°F to 221°F.
Superior Insulation & Durability: Equipped with 3/8" thickened high-density insulation PE foam and heat-shrink tubing for maximum thermal efficiency and UV resistance. The impermeable copper structure resists corrosion, extends lifespan, and minimizes energy loss in all climates. Resists cracking and deformation, and works with all common refrigerants.
Universal Compatibility & DIY-Friendly: Perfect for most ductless mini-split systems (compatible with most 9000-36000 BTU mini split air conditioners or AC systems that require 1/4'' and 3/8'' settings). Pre-flared, pre-insulated, and meticulously packaged with protective dust plugs to maintain cleanliness during transit and installation.
