Tadpole Tapes & Seals

For sealing under light pressure

Manville's tadpole tapes seal tightly under light pressure while resisting flame and prolonged high temperatures. These resilient and non-absorbent gasketing materials are formed by wrapping heat resistant cores with a variety of specially treated cover materials.

Flexible, tough, available in many styles and sizes, tadpole tapes are suitable for aerospace, power generation, marine power plant and many other applications. They are especially suited for applications where doors and other closures seal against the bulb of the tadpole packing. Available in a variety of standard and custom styles, materials and constructions.

Best Suited For:

  • Ideal for sealing aircraft engine mounting rings, turbine flanges and combustion chamber inlets
  • Effectively seal under light pressure, such as under light metal flanges where bolting force is limited
  • Conform to and easily seal uneven mating surfaces
  • Will not harden when exposed to prolonged high temperatures

Manville's JM Clipper Tadpole Tapes are available in a wide range of design and material styles for varied applications and service conditions.

AF 150-10

The most economically priced of the highly resilient, metal mesh core types. It consists of a knitted Inconel® mesh core and a cover of fiberglass cloth with Inconel wire reinforcement. The cover is treated inside and outside with a neoprene compound. The tail assembly is stitched.

AF 150-12

Offers high recoverability at constant temperatures to 500 °F. It consists of a knitted Inconel mesh core with a cover of fiberglass cloth reinforced with Inconel wire. The cover is treated with silicone rubber inside, and a flameproof neoprene base compound with aluminum finish outside. The tail is stitched with fiberglass thread.

AF 150-15

Recommended where there is movement of the mating metal flanges. It consists of a knitted Inconel mesh core with a cover of fiberglass cloth. The cover is treated inside and outside with PTFE suspensoid. The tail assembly is stitched.

AF 150-20

Lightest weight, easiest to compress, and has the highest recovery factor of all Tadpole tapes. It consists of a knitted Inconel mesh core with a cover of Inconel mesh. The cover is coated with neoprene cement on the inside and a neoprene compound on the outside. The tail assembly is cemented.

AF 151-18

Provides increased sealability with a foil wrapping over the core. It consists of a knitted Inconel mesh core wrapped with aluminum foil and a cover of fiberglass with inconel wire reinforcement. The cover is coated with neoprene cement inside and neoprene cement with an aluminum finish outside. The tail assembly is stitched.

AF 156-15

Treated with a PTFE suspensoid to reduce friction. It consists of a fiberglass twisted rope core, with a cover of fiberglass fabric, treated inside and out with a PTFE suspensoid. The tail structure is stitched.

AF 160-21

Withstands the highest operating temperatures of any Tadpole structure. It consists of a core of knitted inconel mesh and soft refractory fiber wrapped in aluminum foil. The cover material consists entirely of fine, braided Inconel wire. The tail assembly is stitched.
