At Kriloha Ltd., we understand that “extreme” is a relative term. While most industrial processes operate within the limits of flexible graphite, there is a specialized tier of engineering—found in aerospace, smelting, and advanced energy—where temperatures routinely exceed 600°C. In these environments, carbon-based seals simply cannot survive. The Kriloha Mica Spiral Wound Gasket is our definitive solution for these ultra-high temperature boundaries. As a global leader in high-performance sealing, Kriloha Gaskets has engineered this product to provide a permanent, non-oxidizing barrier for the world’s hottest piping systems.
The technical superiority of this gasket lies in its Phlogopite mica filler. Mica is a naturally occurring mineral with a plate-like crystalline structure that remains physically stable at temperatures where other materials vanish. While graphite begins to oxidize at 450°C in the presence of air, mica remains unaffected even at 1000°C. When Kriloha winds this mineral into our precision V-shaped metallic strips, we create a seal that acts like a “thermal shield.” This is particularly critical in applications like gas turbines or thermal oxidizers, where the seal must remain gas-tight for years without the risk of filler “burn-out.”
Furthermore, Kriloha’s Mica SWGs offer a unique advantage: electrical insulation. In many modern energy applications, such as high-temperature fuel cells or specialized electrolysis units, the gasket must seal the media while preventing electrical current from jumping between flanges. Because mica is a world-class dielectric, our gaskets provide this dual functionality flawlessly. We pair this mineral filler with specialized high-temperature alloys like Inconel 625 or 310 Stainless Steel, ensuring that the mechanical “spring” of the gasket is preserved even at a dull red heat.
As a top supplier of rubber seals and gaskets, Kriloha Ltd. applies the same rigorous quality standards to our mineral seals as we do to our elastomeric ones. We utilize a proprietary Mica-Binding process that ensures the mica flakes remain flexible during installation, allowing the gasket to conform to flange irregularities despite its high mineral content. When you specify a Kriloha Mica SWG, you are investing in a product that is designed to outlast the equipment it seals, providing undisputed thermal and electrical security in the most punishing environments known to industry.
