Premium Grade Copper: ASTM B280 and C12200
The copper tubing is made from 99.9% pure copper and manufactured to HVAC refrigerant tubing requirements. ASTM B280 and C12200 copper support durability, pressure resistance, corrosion resistance and superior heat transfer.
High-purity copper for long service life.
Excellent thermal conductivity for refrigerant transfer.
Strong pressure tolerance for modern HVAC refrigerants.
Suitable for professional HVACR installation and replacement projects.
Advanced Insulation for UV and Moisture Protection
The insulation is made from high-density closed-cell foam, polypropylene or black rubber options. It is designed to resist UV exposure, moisture and temperature variation from -40℃ to 120℃.
Thermal Efficiency
Insulation reduces unwanted heat transfer between the refrigerant line and surrounding environment, helping HVAC systems maintain stable cooling and heating performance.
Condensation Control
Closed-cell insulation helps prevent pipe sweating, dripping and moisture buildup, protecting walls, ceilings and nearby building materials from damage.
