TAPE: FIBERGLASS

PLAIN. AGIS plain fiberglass tape is a tightly woven tape manufactured from texturized fiberglass yarn; it contains no compound, cement or wire. Selvaged edge will not fray or unravel. Meets U.S. Coast Guard requirements for incombustible material. Used in service conditions characterized by temperatures to 1000 F. Retains 50% tensile strength at 700 F and as much as 25 % at 1000 F. Will not swell, stretch, shrink or change chemically during prolonged exposure to water.

Premium Grade. Densely woven tape features surface-applied heat treatment.

Applications: Tadpole gasket covering, flange gasketing, oven door seals, pipe wrapping and insulation

Commercial Grade. Looser weave than premium grade, not heat treated.

Applications: Flange gasketing, oven door seals, pipe wrapping and insulation

BOLT-HOLE. AGIS bolt-hole fiberglass tape (also known as drop-warp tape) is a tightly woven tape manufactured from texturized fiberglass yarn; it contains no compound, cement or wire. Selvaged edge will not fray or unravel. Similar construction as plain tape, but without fill yarns in the center of the tape; this permits easy bolt insertion in flange gasketing requirements. Not heat treated. Meets U.S. Coast Guard requirements for incombustible material. Used in service conditions characterized by temperatures to 1000 F. Retains 50% tensile strength at 700 F and as much as 25 % at 1000 F. Will not swell, stretch, shrink or change chemically during prolonged exposure to water.

Premium Grade. Densely woven tape.

Applications: Tadpole gasket covering, flange gasketing, oven door seals, pipe wrapping and insulation

Commercial Grade. Looser weave than premium grade..

Applications: Flange gasketing, oven door seals, pipe wrapping and insulation

PLAIN, VERMICULITE COATED This is a plain, tightly woven tape manufactured from texturized fiberglass yarn, coated with a special vermiculite compound and dyed blue. Meets U.S. Coast Guard requirements for incombustible material. Used in service conditions characterized by temperatures to 1800 F. Will not swell, stretch, shrink or change chemically during prolonged exposure to water. Because of the vermiculite coating, the tensile strength and chemical resistance are greatly enhanced over plain fiberglass tape.

Applications: Tadpole gasket covering, flange gasketing, oven door seals, pipe wrapping and insulation

BOLT-HOLE, VERMICULITE COATED Manufactured as drop warp tape (bolt hole tape). Similar construction as plain tape, but without fill yarns in the center of the tape; this permits easy bolt insertion in flange gasketing requirements.

Applications: Tadpole gasket covering, flange gasketing, oven door seals, pipe wrapping and insulation

RUBBERIZED FOLDED GASKETING TAPE. Style P37G is a tightly woven fiberglass base tape with a unique SBR rubber coating. The coating allows the rubber to seep into imperfections in the sealing surfaces and, when hardened, creates an airtight seal. Suitable in service conditions where temperatures and pressure do not exceed 380 F and 180 PSI respectively. May be manufactured to virtually any thickness and length by layering the 1/16" thick plies of material and then calendering them.

Options: Available with brass wire insert when greater tensile strength is required.

Applications: Wherever an airtight seal is critical.


TADPOLE TAPE

Named because of its end view configuration, appearing as a head and tail of a tadpole. The core (or head) consists of a bulb, which is the sealing area; the tail is used for fastening. Used where limited bolting force is available and where gasket must conform to uneven surfaces.

RUBBERIZED FIBERGLASS. Style P57G is basic tadpole tape gasket with fiberglass rope core covered by tightly woven fiberglass cloth coated with SBR rubber. Suitable for temps to 380 and pressures to 180 PSI.

Applications: Boiler doors; other applications requiring airtight seal.

SEWN FIBERGLASS, CERAMIC OR SILICA. Style P61G is designed for service temps in the 400 - 3000 F range. Covers are machine-sewn and may include the following materials/configurations:

  • Fiberglass cover and bulb
  • Inconel wire-inserted ceramic cover and ceramic rope bulb
  • Inconel mesh core (when subjected to repeated door opening and closing)
  • Teflon® impregnated fiberglass cover (where chemical resistance is crucial)
  • 304SS mesh cover (where additional abrasion resistance and durability are required).
  • Other cover/core combinations available:
    • To 1000 F: Glass cover, glass core
      Glass cover, inconel mesh core
    • To: 1600 F: Silica cover, ceramic core
      Silica cover, inconel mesh core
    • To: 2300 F: Ceramic cover, ceramic core
      Ceramic cover, inconel mesh core

TAPE: CERAMIC

WOVEN CERAMIC FIBER A superior insulating tape capable of withstanding temperatures to 2300 F. Excellent resistance to thermal shock, corrosive attack, breakdown due to mechanical vibration and stress. Contains approximately 20% organic fiber. Alternative inserts: Inconel wire is inserted for greater tensile strength; suitable for temps to 2300 F. A glass filament may be inserted for use as a dielectric, suitable for temps to 1200 F.

Options: For personnel protection and fire retardation, heat treated tape is recommended. Heat treatment removes the organic fibers, but reduces the thickness and strength of the tape slightly.
