Tadpole Seals

Our Tadpole Seals are designed to provide a high temperature thermal seal in industrial laboratory, commercial and residential ovens and dryers with a maximum continuous operating temperature of 1000A F / 540A C. Constructed with Type E fiberglass, the bulb may be filled with various constructions of either fiberglass or stainless steel in order to achieve the proper design compression.

Additionally, the bead of the tadpole may also be filled to accommodate various door constructions. Textile engineering coupled with our heat treating and coating expertise, allow for a wide variety of constructions in order to meet unique environmental and design constraints.


Core diameter are typically 1/4a - 3/4a
Both the Core and Bead may be filled with the following optional materials or left hollow :

Type 304 Stainless Steel knitted wire hollow bulb
Type 304 Stainless Steel Solid mesh
Knitted type E fiberglass rope

In addition, the gasket can be provided with a stainless steel knitted jacket or a coating of either PTFE or Silicone rubber. The bead (Dimension B) may also be eliminated. Our engineering staff will be happy to assist in meeting all your design needs.
