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.
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.
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.
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.
