High-Temperature Custom Seals for Boilers, Furnaces & Industrial Equipment
Tailored Sealing for Thermal Processing & High-Heat Enclosures

Our custom high-temperature seals are purpose-built for industrial applications requiring thermal, pressure, and vibration resistance. These static and dynamic sealing solutions are designed to maintain integrity under extreme conditions, supporting continuous operation in boilers, ovens, furnaces, kilns, and cookers.

Each seal is manufactured to your specifications for precise fitment, minimising heat loss, leakage, and equipment fatigue. We offer material flexibility to suit your application — from fibreglass and silica-based ropes to ceramic fibre, aramid, and custom gasket constructions.

Common Applications:

• Boiler inspection and burner door seals
• Furnace and oven door seals for thermal retention
• Kiln car seals for refractory lining and heat shielding
• Cooker and food-processing seals requiring durability and hygiene compliance
• Burner block insulation and gap sealing

Key Benefits:

• Resistant to temperatures up to 1000°C (depending on material)
• Custom profiles for flat, round, U-shaped, and irregular sealing surfaces
• Options for woven, braided, layered, or die-cut construction
• Supplied with or without mesh cores, metallic reinforcements, or coatings

For sealing boiler doors and other access panels, we also offer Fibreglass Rope Lagging as an off-the-shelf alternative.
