Stainless gasket

coatedstainless steel meshtadpole

Overview
The vermiculite-coated fiberglass tadpole gasket tape with an Inconel or stainless steel mesh core is a high-temperature door seal designed for industrial furnaces, boilers, kilns and ovens. The vermiculite coating on the outer fiberglass layer increases heat and abrasion resistance, while the wire mesh core provides structural support and repeated compression strength for frequent door cycling.

Key Features

• Vermiculite-coated fiberglass outer layer for enhanced heat and abrasion resistance
• Inconel or stainless steel mesh core for high-temperature strength
• Designed for reliable sealing of furnace, kiln and oven doors
• Available in multiple bulb diameters and tail widths for retrofits
• Flexible profile for straightforward installation on flanges and door edges
• Custom lengths available to specification

RFQ – Frequently Asked Questions

• What is the purpose of a tadpole gasket? Tadpole gaskets provide a compressible seal with a flat tail for easy attachment to door flanges and a bulb that compresses to form the seal.
• Why use vermiculite-coated fiberglass? The vermiculite coating improves thermal stability and abrasion resistance compared with uncoated fiberglass, extending service life in high-temperature environments.
• What is the advantage of an Inconel core? Inconel wire mesh offers superior high-temperature mechanical strength and corrosion resistance compared with standard stainless steels.
• Can the gasket be customized? Yes. Bulb diameter, tail width and overall length can be produced to customer specifications.
