Industrial-grade insulation features UV- and wear-resistant coating with non-frictional surface to facilitate pulling. White insulation reflects solar heat, is water-resistant, and features hardened, but ductile surface that allows bending without kinking.

RectorSeal Introduces Time-Saving Paircoil-- Pre-insulated, Linesets for A/C Systems

Rectorseal Corporation
2601 Spenwick Dr.
Houston, TX, 77055

Press release date: February 4, 2014

Paircoil features a durable industrial-grade insulation with a UV light and wear-resistant embossed coating and a non-frictional surface for easy pulling.

RectorSeal® Corp., Houston,  a leading manufacturer of quality HVAC/R products, introduces Paircoil™, pre-insulated, malleable linesets designed specifically to expedite installations of ductless mini-split and conventional air-conditioning systems in North America.

Paircoil is sold in 65-foot (20-meter) rolls of either 1/4 (6.35-mm) and 3/8-inch-diameter (9.52-mm); or 1/4 and 1/2-inch-diameter (12.7-mm) copper liquid/suction line sizes. Paircoil's durable 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 competitively-priced Paircoil's white insulation efficiently 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.

Paircoil other features include:
  • Ductility allows bending, shaping and forming without kinking;
  • Thin 3/8-inch (9.52-mm) insulation thickness allows space with all lineset protection ducting such as Fortress™ and SlimDuct®.
  • Accommodates operating pressures of up to 600-psi.
  • Comes with straight, plain ends;
  • Meets ASTM-International specification standards B280 seamless copper tube for air-conditioning and refrigeration field service; and C534 for preformed flexible, elastomeric cellular thermal insulation;
  • Packaged in a fully-illustrated sturdy, protective cardboard carton that's easily multi-stacked without lineset damage;
  • Easily decoupled without cutting tools for reaching separated terminal connections;
  • Available through all major HVAC wholesale distributors;
The addition of Paircoil makes RectorSeal a comprehensive line of ductless mini-split air conditioning installation accessories offering everything except the air conditioning unit itself. RectorSeal offers the following air-conditioning installation support products that are all backed by RectorSeal's customer and technical support departments:
  • condenser equipment mounts and brackets;
