General Description:
Insulseal Knitted fiberglass rope is manufactured in dense and soft varieties, round or square, to meet exact requirements. It is available in standard sizes from 1/8" to 1-1/2" diameters. Quick turnaround is available for larger sizes on request. Insulseal is an ideal non-hazardous replacement for outdated high-temperature ropes.

Typical Applications:
Insulseal is the best choice for new or alternative gasketing in pipe wrap, boiler, furnace, oven, gas fireplace, wood/gas/tile stove, thermal insulation, glass manufacturing, flange gasketing and fireproof safe applications.

Optional Features and Benefits:


Graphite Coating: Provides more abrasion
resistance. Black color renders a more integrated, blended appearance for the unit. Graphite Coating is permanent at high temperatures.

Pressure-sensitive adhesive: When
applied to one side of tape, this feature
creates economies in production. Eliminates
messy (and potentially dangerous) glues
and cements from the workplace.

Vermiculite Coating: Increases the
temperature resistance over that of regular
uncoated fiberglass.
