Tadpole & Hat-Seal Gaskets

Tadpole and Hat-seal gaskets are useful due to the thickness and compression of the bulb material which conforms to uneven surfaces where gasket tape will not be effective, and allows for rebound from compression. “Bulb & Tail” or “Tadpole” Gaskets may be ordered by specifying the O.D. and location of the bulb(s) plus the length of the tail.

“Hat-Seal” Gaskets may be ordered by specifying the rectangular dimension and location of the head(s), as well as the length of the tail(s).

Typical Size Ranges
Tadpole Bulb	1/4" - 2"
Tadpole Tail	1/2" - 4"
Hat-Seal Head	1" - 6"
Hat-Seal Tail	1" - 4"

Tadpole & Hat-Seal Gaskets

High-temperature Tape is used for thermal and electrical insulation in Marine, Industrial, Automotive, Aerospace, and Welding applications. It may be used to seal oven or furnace doors as well. A wide variety of sizes and types of tape are available to accommodate requirements for the most extreme temperature ranges.

Many tapes are available in both plain and Bolt-hole (Drop-warp) styles. Due to the nature of the applications for high-temperature tapes, only a few styles have an adhesive back.

Custom Flat-Face Gaskets

Textile and ceramic paper can be fabricated into a variety of shapes to be used for door and stove gaskets, flange gaskets, and many other applications.
