Fibreglass Braided Seals – 550°C High-Temperature Insulation
Flexible Sealing for Ovens, Boilers & Industrial Equipment

Engineered for continuous high-heat exposure, our 550°C-rated fibreglass braided seals combine thermal insulation and mechanical durability. These asbestos-free seals are manufactured with a fibreglass core and over-braided with high-temperature glass yarn to provide reliable performance in industrial thermal systems.

Key Features:

• High Temperature Rating: Performs in continuous environments up to 550°C
• Available Profiles: Choose from square or round braid formats for optimal fit
• Custom Densities: Select from multiple densities depending on pressure and insulation needs
• Safe & Non-Toxic: Asbestos-free, incombustible, and compliant with industrial safety standards
• Thermal Insulation: Low thermal conductivity helps minimise heat loss and energy waste

Common Applications:

• Furnace and oven door sealing
• Flue and duct seals in boiler rooms
• Boiler close-up kits and steam system insulation
• Pipe and vessel lagging where heat retention and sealing are critical
