Where is this gasket commonly used

It is widely used for boiler doors, furnace doors, kiln doors, ovens, access panels, heat exchangers, and industrial sealing points where heat resistance and compressibility are required.

Does the gasket help reduce heat loss

Yes. A properly compressed tadpole gasket reduces hot air leakage and improves sealing efficiency, which can reduce heat loss and improve equipment safety.

Can you supply cut lengths instead of rolls

Yes. We can supply continuous rolls or cut-to-length pieces for production lines and maintenance kits.

Product Q&A

Q:What is a tadpole gasket and why is it used on boilers and furnaces

A tadpole gasket is a thermal sealing tape with a round bulb and a flat tail. The bulb compresses to fill gaps and maintain sealing under thermal cycling, while the tail fixes the gasket onto the door frame or flange.

Q:Is this gasket fiberglass or ceramic fiber

This page describes the fiberglass boiler tadpole gasket. If you need ceramic fiber tadpole gasket for higher temperature service, we can supply a ceramic fiber jacket version. Tell us your max temperature and application so we propose the correct construction.

Q:Can I get adhesive backing on the tail

Yes. PSA backing can be added to the tail for easier installation. Please note that adhesive performance depends on surface condition and operating temperature, so provide your working conditions for correct selection.

Q:How do I select bulb diameter and tail width

Measure the door gap and compression range. Bulb diameter is usually selected slightly larger than the gap to ensure compression sealing. Tail width should match the mounting surface or channel width.

Q:Can you produce custom profiles and sizes

Yes. We can customize bulb diameter, bulb shape, tail width, tail thickness, density, roll length, and packaging. Send your drawing, dimensions, or a sample.
