Marketing InformationOur products, made from virgin copper never from scrap or recycle virtually eliminates the pinhole leaks, flare cracks and kinking issues that cause installation delays and inspection failures. Our C12200 Cu-DHP, 99.9% pure copper tubes comply with ASTM standard specification, suitable for R407 and R410 gas applications. Half the battle installers face stems from poor-grade tube insulation performance during and after the install especially in mini-split applications. Our patented polyethylene skin resists tears and scratches and dramatically reduces drag through wall openings. Our insulation is low density, closed cell polyethylene. Available in 1/2 inch and 3/4 inch thickness, it's CFC and HCFC gas-free and complies with ASTM C 1427-07 type 1, grade 1 material. Together, they provide a durable, great-looking sheath for the tubing in a variety of applications.
