Fiberglass Square Braided Rope is a high-temperature sealing rope manufactured from E-glass fiberglass yarns using a square braided construction. It is designed for thermal sealing, insulation, and gap filling in high-temperature industrial environments where resistance to heat, flame, and mechanical wear is required.
This square braided fiberglass rope is commonly used as a high-temperature sealing gasket for furnaces, boilers, ovens, stoves, kilns, and industrial heating equipment.
The rope is produced using a square braiding process that forms a dense, uniform cross-section.
Square profile provides better surface contact compared to round ropes
Dense braided structure improves sealing efficiency
Maintains shape under compression
Suitable for static sealing applications
The square braided design allows the rope to sit firmly in grooves, channels, or sealing gaps, reducing air leakage and heat loss.
