Product Description
Tadpole gasket is a flexible high-temperature sealing profile designed for oven doors, furnace doors, access panels and other industrial equipment. The bulb-and-tail geometry provides a compressible sealing zone with a retained tail for mounting, enabling effective sealing on uneven or irregular mating surfaces to reduce heat loss, air leakage, dust ingress and hot gas escape.

Product Overview
The tadpole gasket combines a rounded bulb section for compression and recovery with a tail section that can be clamped, bolted or mechanically retained to a door or frame. Available in a range of cover and core constructions, the gasket is suitable for thermal processing, power generation, exhaust systems and other high-temperature or mechanically demanding applications. Material choices allow optimization for temperature resistance, abrasion resistance and flexibility.

Key Benefits

• Reliable sealing on uneven or irregular surfaces
• Bulb design provides compression and recovery for repeated cycles
• Suitable for oven doors, furnace doors, kilns and access panels
• Customizable profile, bulb diameter, tail width and overall width
• Multiple cover and core material combinations for temperature and wear resistance
• Durable for repeated opening/closing and vibration-prone equipment

Available Material Options
Cover materials: Fiberglass, vermiculite-coated fiberglass, silica, ceramic fiber, silicone-coated fiberglass, PTFE-coated fiberglass, basalt fiber, aluminized fiberglass. Core materials: Fiberglass rope, ceramic rope, stainless steel mesh, stainless steel hollow core, Inconel mesh, silicone sponge. Supply forms: Cut lengths, continuous lengths, custom-fabricated parts. Installation: Clamped, bolted, mechanically retained or custom mounting.

Typical Applications

• Industrial oven door seals
• Furnace door gaskets
• Dryer and kiln access seals
• Boiler and burner inspection doors
• Exhaust and duct access panels
• Thermal processing and heat treatment equipment
• Foundry and power generation equipment

Custom Manufacturing
Custom tadpole gaskets can be produced to customer drawings or on-site measurements. Bulb diameter, tail width, overall width and material construction can be adjusted to match door geometry, sealing pressure and operating temperature for accurate fit and long-term performance.

Why Use a Tadpole Gasket
Compared with flat gasket tape, tadpole gaskets create a defined compression zone and improved recovery after repeated cycles. The bulb accommodates dimensional variation while the tail ensures secure mounting, making this design effective where vibration, thermal cycling or surface irregularities occur.
