Product Overview
BSTFLEX high-temperature tadpole gasket is a bulb-and-tail sealing profile designed for demanding thermal enclosures. It combines a silica cloth outer cover with an internal Inconel core to provide high-temperature resistance and dimensional support for the compressible sealing bulb.

Typical Uses
Recommended for furnace and industrial oven doors, kilns, heat-treating equipment, thermal processing chambers, access panels and other high-temperature enclosures. Available for OEM and industrial replacement applications and customizable to fit installation geometry.

Silica Cloth Tadpole Gasket Construction
The gasket uses a rounded bulb for compression sealing and an extended tail for mechanical attachment. The Inconel core supports the bulb profile while the silica cloth cover provides a high-temperature textile barrier suitable for radiant heat and hot surfaces.

Component / Material / Function
Outer Cover — Silica Cloth — High-temperature protective textile
Core — Inconel — Internal reinforcement for profile stability
Bulb — Silica-cloth-covered core — Primary compressible sealing section
Tail — Silica Cloth — Flexible mounting section for fasteners
Sewing Thread — High-temperature thread — Secures cover and assembly

How Does a Tadpole Gasket Work?
The rounded bulb compresses against the mating surface to form a continuous seal while the tail is mechanically fastened to the equipment frame. The design accommodates minor dimensional variations and thermal movement during heating and cooling cycles.

Functional Sections

• Bulb: Rounded section providing the primary sealing surface.
• Tail: Flat extension for mechanical attachment (clips, screws, retainers).
• Core: Internal reinforcement that supports and stabilizes the bulb.
• Cover: High-temperature textile layer surrounding the core.

Tadpole Gasket vs Tadpole Seal vs Tadpole Tape
These terms describe similar bulb-and-tail sealing constructions. 'Tadpole gasket' is the common product term; 'tadpole seal' and 'tadpole tape' are industry synonyms or variations depending on application and mounting method.

High Temperature Performance
Silica cloth provides resistance to elevated temperatures and radiant heat; the Inconel core helps maintain gasket geometry and repeatable compression under thermal cycling. Actual temperature capability depends on fabric grade, core design, thread selection and exposure conditions.

Key Advantages of the Tadpole Gasket

• Silica cloth outer cover for high-temperature exposure
• Inconel core reinforcement for dimensional stability
