Darco Southern Products are the Metals Industry Standard

Darco Southern’s wide variety of high temperature material and coating options along with our manufacturing capabilities position us to offer thermal protection and gasket solutions for the simple to the most complex applications in the Metal Industry.

Darco Southern’s Tetraglas® Fiberglass, Tetraglas 3000® Silica, Ceramic, and Basalt product groups provide our maximum constant operating temperatures and are the base materials for our standard and our custom made products including hose and pipe insulation covers, protective shields and more.

Darco Southern’s temperature, abrasion resistance, and sealing enhancement coatings and additives offer additional performance capabilities to provide even more solutions for your specific application requirements. Some of these include vermiculite, PTFE, graphite and reflective foils.

Darco Southern’s silicone-coated fiberglass Firesleeve, tape & rope have become an industry standard with their ability to deflect a molten metal splash while providing constant radiant heat protection up to 500°F/260°C.  Firesleeve is the foundryman’s first choice for protecting hoses and cables around the furnace.  Our firesleeve with Hook & Loop closure provides excellent heat protection while allowing easy retrofitting of existing cables and hoses.  Fireblanket can be used to protect larger areas from molten splash and damaging radiant heat.  Regular, uncoated fiberglass sleeves, tape, cloth and rope are also used for thermal shielding and packing around equipment where molten splash is not a primary concern.

In addition to our high temperature gaskets made from our Fiberglass, Silica, Ceramic, and Basalt high temperature textiles, Darco Southern offers a line of compressed non-asbestos materials, PTFE, laminate graphite, spiral wound, metal, and rubber for your specific gasket requirements.
