Shanghai, NingboBSTFLEX silica cloth covered ceramic core tadpole gasket is a flexible high temperature sealing solution designed for furnace doors, industrial ovens, kilns, heat treatment equipment and other thermal processing systems. Its bulb-and-tail profile combines a compressible sealing bulb with an extended mounting tail, allowing the gasket to provide a continuous seal around doors, access panels and equipment openings.
The sealing bulb is formed around a ceramic core and enclosed with high temperature silica cloth. The ceramic core provides structural support to the bulb, while the silica cloth cover provides a heat-resistant outer layer for demanding thermal environments. The tail section can be mechanically secured to the equipment frame to create a reliable perimeter seal.
Also referred to as a ceramic tadpole gasket, ceramic core tadpole seal, silica tadpole gasket or tadpole gasket tape, this construction can be manufactured in custom dimensions and configurations according to the customer's equipment design.
The construction of this tadpole gasket is based on a rounded bulb and an extended tail. Unlike metal-core versions, the sealing bulb uses a ceramic core to provide internal support. The entire construction is covered with silica cloth to create a flexible high temperature textile seal.
| Component | Material | Purpose |
|---|---|---|
| Outer Cover | Silica Cloth | Provides the high temperature textile barrier and protects the internal structure |
| Core | Ceramic | Supports the bulb profile and provides heat-resistant internal structure |
| Sealing Bulb | Silica Cloth Covered Ceramic Core | Forms the compressible sealing section |
| Mounting Tail | Silica Cloth | Provides an attachment area for mechanical installation |
| Sewing | High Temperature Thread | Secures the textile cover around the gasket construction |
A tadpole gasket seals a joint through compression of its rounded bulb. The mounting tail is positioned against the equipment frame and secured with a suitable mechanical fastening method. When the door or panel closes, the bulb is compressed against the mating surface.
The compressed bulb fills the space between the two surfaces and creates a continuous thermal sealing barrier. The flexible textile construction allows the gasket to follow the perimeter of the opening while accommodating normal movement and minor dimensional variations.
The ceramic core supports the bulb from within, while the silica cloth cover protects the gasket construction from direct exposure to the surrounding thermal environment.
A ceramic core can be selected when a high temperature sealing application requires a non-metallic internal structure. Ceramic materials provide excellent thermal resistance and can support the shape of the sealing bulb without introducing a metallic core into the gasket construction.
The choice between a ceramic core, stainless steel core, Inconel core or another reinforcement depends on the application's temperature, compression requirements, mechanical movement and installation conditions.
For thermal equipment where the gasket is primarily exposed to high temperatures and requires a lightweight, heat-resistant internal structure, a ceramic core tadpole gasket can be an effective sealing option.
The silica cloth outer cover is designed for high temperature applications where conventional rubber, polymer or standard textile sealing materials are unsuitable.
Silica textile provides a heat-resistant outer layer around the ceramic core and helps protect the gasket from radiant heat and elevated-temperature exposure. The actual performance of the finished gasket depends on the silica fabric grade, ceramic core construction, sewing thread, gasket dimensions and operating conditions.
BSTFLEX can select the appropriate textile construction according to the customer's temperature and sealing requirements.
The silica cloth cover is designed for demanding thermal environments and provides a protective outer layer around the ceramic core.
The ceramic core supports the rounded bulb and provides a non-metallic internal structure for high temperature sealing applications.
The rounded bulb provides the compression seal, while the extended tail creates a convenient mounting section for attachment to the equipment.
Bulb diameter, tail width, tail thickness, gasket length and overall configuration can be customized to suit the available installation space and required compression.
The flexible textile construction is suitable for equipment that is repeatedly heated, cooled, opened and closed, provided the gasket is correctly selected and installed for the application.
The ceramic core provides an alternative to metal-reinforced tadpole gasket constructions where a non-metallic internal core is preferred.
There is no single standard profile suitable for every furnace, oven or kiln. The bulb size and tail dimensions should correspond to the available gap, compression distance and mounting structure.
BSTFLEX manufactures custom ceramic core tadpole gaskets according to drawings, samples and dimensional specifications. The gasket can be configured for straight sections, circular openings, rectangular frames and other custom equipment geometries.

Ceramic core tadpole gaskets are used in high temperature equipment where flexible perimeter sealing is required around doors, panels and openings.
Furnace doors must maintain a controlled seal while being repeatedly opened and closed during production, inspection or maintenance. A ceramic tadpole gasket provides a compressible bulb that follows the perimeter of the door while the tail is secured to the furnace frame.
The silica cloth and ceramic core construction provides a combination of flexible sealing and high temperature resistance. The profile can be customized according to the furnace door gap, mounting method and required compression.
A silica tadpole seal can be installed around industrial oven doors and access openings where a flexible high temperature seal is required. The bulb is compressed when the door closes, helping reduce the open path between the door and frame.
The mounting tail can be designed to suit the customer's preferred fastening arrangement. This makes the gasket suitable for both new equipment and replacement sealing applications.
Customers may use several different terms when searching for this type of high temperature sealing product. Tadpole gasket and tadpole seal are commonly used for the bulb-and-tail profile, while tadpole tape and tadpole gasket tape are also used by suppliers to describe related flexible sealing constructions.
The terminology does not necessarily define the material. A tadpole gasket can be manufactured with different cover and core combinations depending on the temperature and mechanical requirements of the application.
For this product, the defining construction is a silica cloth cover with a ceramic core.
Choosing the correct gasket requires more than selecting a bulb diameter. The complete sealing environment should be considered before production.
Providing a drawing or sample allows BSTFLEX to evaluate the required profile more accurately and develop a suitable custom gasket construction.
BSTFLEX develops and manufactures high temperature textile products, thermal protection components and flexible sealing solutions for industrial applications. Our tadpole gasket manufacturing capability supports custom profiles rather than limiting customers to a single standard size.
A ceramic core tadpole gasket is a bulb-and-tail high temperature gasket that uses a ceramic core inside the sealing bulb and a high temperature textile cover around the construction.
The silica cloth forms the external high temperature textile layer and protects the internal ceramic core while providing the exposed sealing surface.
A tadpole seal is a flexible sealing product with a rounded bulb and mounting tail. It is commonly used around furnace doors, oven doors, kilns and thermal equipment openings.
