Fabric sealing strip

mineral fibermetal wiretadpole

Overview
Basalt fabric cover wire mesh core tadpole gasket is a high-temperature sealing component designed for furnace doors, industrial ovens, thermal processing equipment, stoves and heat-resistant enclosures where a flexible, heat-resistant perimeter seal is required.

Construction
The gasket combines a woven basalt fabric outer cover with an internal wire mesh core. The basalt fabric provides a durable thermal barrier and protects the internal structure from direct exposure to heat and mechanical contact, while the wire mesh core provides reinforcement, resilience and profile retention during repeated compression.

Tadpole Profile
The tadpole-style construction creates a rounded sealing bulb and an integrated mounting tail. When installed around a door, panel or equipment opening, the bulb compresses against the mating surface to reduce heat leakage, while the tail provides a practical attachment area for securing the gasket to the frame or retaining structure.

Component — Function
Component: Basalt woven fabric cover — Function: Provides the external heat-resistant textile layer and protects the internal core from direct contact with the surrounding environment.
Component: Wire mesh core — Function: Provides internal reinforcement, resilience and structural support for the sealing profile.
Component: Sealing bulb — Function: Compresses against the mating surface to form the primary thermal sealing area.
Component: Mounting tail — Function: Provides a practical area for attaching the gasket to a door, frame, panel or retaining structure.

Why use a basalt woven fabric cover?
Basalt fiber is a mineral-based fiber produced from basalt rock and, when woven into fabric, creates a flexible textile suitable for high-temperature protective and sealing applications. In this gasket the basalt cover forms the outer working layer, offering thermal protection while allowing the gasket to flex around doors, panels and irregular sealing paths.

• High-temperature textile construction
• Flexible woven structure
• Good resistance to thermal exposure
• Suitable for demanding industrial environments
• Can accommodate curved and irregular sealing paths
• Provides a protective outer layer for the internal core

Wire mesh core for structural support
The internal wire mesh core provides reinforcement throughout the sealing bulb and helps the gasket maintain its intended shape during handling, installation and compression. The mesh core can flex and deform with the gasket, making it suitable for curved surfaces or applications with movement between mating components. Wire material, mesh construction and core configuration can be selected according to operating environment and mechanical requirements.

How the tadpole gasket creates a thermal seal
The tadpole gasket concentrates sealing around a rounded bulb rather than across a wide flat strip. Typical sequence:

• Positioning: Tail is positioned along the door, frame or equipment perimeter.
• Attachment: Tail is secured using the fastening or retaining method appropriate for the equipment.
• Compression: Closing the door or panel presses the bulb against the mating surface.
• Surface conformity: The flexible profile follows minor variations in the sealing surface.
• Thermal separation: The gasket forms a heat-resistant barrier around the opening or joint.

Applications

• Industrial oven doors
• Furnace doors
• Thermal processing equipment and chambers
• Stoves and heating equipment
• Industrial enclosures and inspection doors
• OEM thermal equipment and replacement gasket programs

Advantages of basalt fabric + wire mesh construction

• Thermal protection from basalt woven fabric
• Profile retention from wire mesh core
• Flexibility to conform to curved sealing paths
• Dedicated compression zone via the rounded tadpole bulb
• Mechanical protection from the woven outer cover
• OEM integration: custom bulb and tail dimensions available

Custom manufacturing
Custom basalt fabric tadpole gaskets can be manufactured to match bulb diameters, tail widths, lengths, profile geometries and core constructions according to application requirements, drawings or samples. Selection of fabric grade, wire mesh type and profile geometry should be based on operating temperature, compression conditions and mechanical requirements.
