Heat-Resistant Materials

Materials and Products

McNeil offers a wide variety of refractory materials and products, including refractories, ceramic fiber, fire brick, fiberglass and silica textiles and gaskets. Some materials are manufactured internally, while others are outsourced. In either case, our goal is to provide the highest-quality materials for our customers.



Refractories are essential in any industrial unit exposed to extremely high temperatures, such as furnaces, kilns, boilers and incinerators. They are more heat-resistant than metal, making them the best choice to withstand excessive heat due to high-temperature refractory coatings. We have all the refractory materials you need, and our expert staff can help you determine what will work best.

At McNeil, we offer industrial refractory products from many popular suppliers, such as Plibrico®. We also make some products ourselves to ensure a high-quality refractory every time. Our inventory includes:

  • Plastics – HyRate®/gunning plastics
  • Castables – dense, insulating, low cement
  • Mortars – servicing mixes
  • Pliflow® Pumpables – pli-shot
  • Gunning mixes – Al-Tuff® system
  • Redi-shapes – anchors
  • And more

Our high-temperature gaskets are specifically designed for heat-sensitive industrial solutions up to 3,000ºF. The gaskets are custom-sized and shaped to meet your exact requirements. We use high-quality die-cut, hand-cut and slit products that always come from non-metallic material with no asbestos.

Our gaskets are a top choice for numerous reasons, including:

  • Die-cut parts are an economical way to meet gasket, spacer and seal requirements.
  • Textile-covered products are ideal for applications that require repeated use or ease in handling and installation.
  • Special parts made from Fiberfrax® Board, Fiberfrax® Paper and Fiberfrax® Lo-Con Felt offer diverse engineering applications.
