RectorSeal® Corp. has introduced the Paircoil™, pre-insulated, malleable linesets designed specifically to expedite installation of ductless mini-split and conventional air-conditioning systems in North America. Paircoil is sold in 65-ft rolls of either .25 and 3/8-in-diameter; or .25 and .50-in-diameter copper liquid/suction line sizes. Paircoil's industrial-grade insulation features a UV light and wear-resistant coating with a non-frictional surface making it easy to pull. It also features embossed incremental one-meter inscriptions for hands-free measuring. The Paircoil's white insulation reflects solar heat, is water-resistant, and features a hardened, but ductile surface. Unlike the industry standard of black, spongy and easily-torn foam insulation, it doesn't absorb moisture or prematurely disintegrate from UV light or freeze/thaw cycles.
