Darco Southern Tetraglas-T® tacky cloth material is one of the most widely used gasket materials in the boiler industry. With the unique ability to seal against pressures up to 300psi and operating temperatures up to 500°F/260°C, Tetraglas-T tacky cloth offers the best of both worlds when it comes to gasket requirements in boilers. The versatility of our tacky cloth material allows us to produce tadpole gaskets, ring and full face gaskets, manhole and handhole gaskets, tapes, groove packing, as well as custom combinations to provide solutions for your boiler gasket applications.
Our Tetraglas® fiberglass, Tetraglas 3000® silica, ceramic, and basalt product groups are available in the form of woven cloth, needled blanket, tape, rope, and sleeving. These materials provide our maximum constant operating temperatures and are the base materials for our standard and our custom made products including tadpole tapes, gaskets, hose and pipe insulation covers, protective shields and more.
Various temperature, abrasion resistance, and sealing enhancement coatings and additives offer additional performance capabilities to provide even more options for your specific application requirements. Some of these include vermiculite, PTFE, graphite, and reflective foils.
