High Temperature Gaskets

Sealing the Gap Between Performance and Failure.

McAllister manufactures high-temperature gasket solutions engineered to seal extreme-heat environments where conventional gasketing materials fail. Designed for industrial, energy, and OEM applications, our gasket systems help prevent heat loss, control leakage, and maintain thermal integrity under continuous thermal cycling and demanding operating conditions.

Our custom-engineered gasket solutions are available in a range of high-performance materials and configurations to accommodate varying temperatures, pressures, flange geometries, and sealing requirements. From exhaust systems and process equipment to furnace doors and industrial enclosures, each solution is built to deliver reliable long-term performance in harsh environments.

High-Temperature Performance Engineered to maintain sealing integrity at extreme temperatures where conventional gaskets and tapes fail.

Custom Configurations Available in a range of materials, densities, and profiles to match specific gap dimensions and sealing requirements.

Versatile Applications Suitable for furnace and oven door seals, exhaust sealing, industrial enclosures, and anywhere thermal or gaseous leakage needs to be controlled.

Consistent, Reliable Compression Designed to maintain consistent compression and seal integrity through thermal cycling and repeated open and close cycles.

PRODUCT TYPES

Tadpole Tapes

A bulb-and-tail sealing tape used for furnace doors, oven seals, and industrial enclosures requiring a compressible, high-temperature gasket solution. Service temperature to 2300° F (1220° C).

Tacky Folded Tapes

Pressure-sensitive, high-temperature tapes designed for sealing joints, overlaps, and irregular surfaces where adhesion and thermal resistance are both required.

Tacky Cloths

Flexible, adhesive-backed cloth sealing materials used to seal gaps, wrap components, and provide thermal and gaseous containment in tight or irregular spaces.

Tacky tadpole tapes

Pressure-sensitive, high-temperature tadpole tapes designed for sealing furnace doors, access panels, and other applications requiring a compressible gasket with adhesive-backed installation.
