Tadpole Gaskets

Constructed from various materials, including type 304 stainless steel, Inconel®, fiberglass (Tetraglas®), silica (Tetraglas 3000®), tacky cloth (Tetraglas-T®), basalt, and ceramic, our tadpole gaskets provide a high-temperature thermal seal for a range of environments and temperatures. We offer standard tadpole gasket products and welcome the opportunity to develop a custom tadpole gasket around your design requirements. Our vertically integrated manufacturing and engineering capabilities allow us to design, prototype, and produce optimal gasket solutions in a minimal time frame. All of our tadpole gaskets are designed to be high-temperature thermal seals for a variety of applications, including boilers, industrial furnaces, residential fireplaces, and commercial, industrial, and laboratory ovens and dryers.
