Fabric sealing strip

metalceramictadpole

Product Overview The ceramic fabric cover Inconel core tadpole gasket is a high-temperature bulb-and-tail sealing solution for furnace doors, industrial ovens, kilns and thermal processing equipment. It pairs a flexible ceramic textile outer cover with an Inconel internal core to deliver stable sealing geometry and thermal protection for demanding industrial applications.

Product Construction The gasket uses a two-material construction: a ceramic fabric outer cover and an Inconel internal core. Each component performs a distinct function to ensure sealing performance and service life.

• Outer cover — Ceramic fabric: Provides the external thermal barrier and a flexible sealing surface
• Internal core — Inconel: Supplies structural support, dimensional stability and bulb shape retention
• Mounting tail — Ceramic textile construction: Provides the attachment area for fixing the gasket to doors or frames
• Sewing — High-temperature thread selected per application: Secures the fabric around the core

How the Tadpole Gasket Works The design features a rounded sealing bulb linked to a mounting tail. The bulb compresses against the opposing surface when a door or panel closes, while the Inconel core maintains bulb geometry under compression and thermal cycling. The ceramic cover protects the core from direct exposure to heat and abrasive atmospheres.

Ceramic Fabric Outer Cover The ceramic fabric is selected for thermal resistance and flexibility. Its woven construction allows the gasket to follow curved sealing paths and protects the Inconel core from direct flame, radiant heat and particulate contact. Fabric grade is chosen based on continuous and peak temperature, atmosphere and installation requirements.

Inconel Core for Structural Stability The metallic Inconel core provides predictable compression behavior, dimensional stability and mechanical support unmatched by brittle ceramic cores. Core diameter and construction are selectable to match sealing gap, compression level and cyclic operation demands.
