Product Description

Ceramic Fiber Fibre Square Round Braided Gasket Rope is a high temperature sealing rope engineered for insulating and sealing doors, joints, flanges, and access covers exposed to extreme heat. The rope is braided from ceramic fiber yarn to form a dense, resilient structure that delivers dependable sealing performance while resisting thermal shock, vibration, and mechanical wear.

This braided gasket rope is supplied in square and round profiles, making it suitable for a wide range of industrial sealing gaps. It is commonly used in boilers, furnaces, kilns, ovens, incinerators, exhaust systems, heat treatment equipment, and other thermal processing installations where stable sealing and insulation are required.

Key Benefits & Applications

Installation Notes

Select a rope size slightly larger than the sealing gap to ensure compression sealing. Clean the sealing surface before installation. Fix the rope using suitable high temperature adhesive or mechanical fastening when required. Avoid over-compression that may reduce rope resilience over time.

Frequently Asked Questions

What is the difference between square and round braided gasket rope?
Round rope is typically used for groove channels and curved paths. Square rope is preferred for flat sealing faces and door edges where uniform surface contact is needed.
What temperature can this ceramic fiber gasket rope withstand?
For continuous operation, it is used up to 1100°C, with short-term exposure up to 1260°C depending on the fiber grade.
Can this rope be used as a furnace door seal?
Yes. It provides both insulation and sealing, helping reduce heat loss and improving temperature stability in furnaces and kilns.
How do I choose the correct rope diameter or size?
Measure the gap width and depth. Choose a size that allows for 10% to 30% compression when the door is closed.
Will the rope shrink after heating?
Minor initial shrinkage may occur during first heat exposure as binders burn off. Once stabilized, it maintains its shape under normal compression.
Can this be used for exhaust sealing?
Yes, it is suitable for high-temperature exhaust doors and joints. For high-velocity gas environments, a denser braid is recommended.
