Flat gasket

aramidtadpolefiberglass

Product Description
Aramid cover fiberglass core tadpole gasket tape designed for furnace doors, boiler doors, industrial ovens, kilns and other high-temperature equipment. The aramid outer cover improves abrasion resistance while the fiberglass core provides flexibility, resilience and thermal insulation. The tadpole profile combines a round bulb for compression sealing with a flat tail for attachment to metal frames and access doors. This design reduces heat loss, limits smoke and air leakage, and maintains sealing performance under repeated thermal cycles and mechanical stress.

Key Benefits

• Aramid outer cover for abrasion resistance
• Fiberglass core for thermal insulation and bulb retention
• Compression seal suitable for doors, access panels and expansion joints
• Resistant to mechanical wear, vibration and high temperatures
• Customizable bulb diameter, tail width and length
• Suitable for sealing in furnaces, ovens, kilns and boilers

Applications

• Furnace doors and access panels
• Boiler doors and flanges
• Oven doors and heat-processing equipment
• Expansion joints and sealing gaps
• Kilns, furnaces and thermal processing systems

How It Works
The tadpole shape features a rounded bulb section that compresses to form a seal against door flanges or frame edges while the flat tail enables secure attachment to metal surfaces. The aramid cover protects the surface from abrasion and the fiberglass core provides flexibility and thermal insulation, enabling the gasket to perform under repeated opening/closing cycles and high thermal stress.
