Automotive exhaust repair paste that lubricates joints and creates tight seals during assembly. Holts Firegum Exhaust Paste gives DIYers and garage mechanics confidence when tackling stubborn leaks. Will the paste stop leaks quickly and hold up to high exhaust temperatures?
⚡ At a Glance
- • Seal Strength: Heat-setting formula fills gaps then sets hard to create durable, airtight joints
- • Best for: DIYers and garage mechanics carrying out exhaust repairs and on-site fixes
- • Not ideal for: Visible finish areas where appearance matters or tasks requiring permanent welding
Lubricating assembly paste that sets hard under heat and withstands high temperatures. Compatible with exhaust systems, flues and boiler pipes for multi-purpose sealing.
Rapid Leak Sealing – thanks to a lubricating, pliable paste
Lubricating formulation allows parts to slide together and the compound fills irregularities; clamping or tightening seats joints before the compound cures. Curing occurs when the assembly heats during normal operation, producing a hard seal.
Quickly stops common exhaust leaks on imperfect fits, reducing bench time. Useful for roadside repairs or quick garage fixes where fast, reliable sealing is needed.
High-Temperature Durability – with a heat-setting compound rated to 1000°C
Compound chemistry hardens under thermal exposure and resists breakdown at elevated temperatures, maintaining bond strength rather than remaining soft. Heat resistance is explicitly specified up to 1000°C.
Maintains a solid joint under typical exhaust temperatures and vibration. Suitable for repeated heating cycles found in everyday vehicle use.
Versatile Application – with compatibility across exhausts, flues and boiler pipes
Formulation is suitable for metal sockets, pipes and clamps and is described as resistant to heat and vibration. Instructions recommend removing rust and applying directly from the tube before assembly.
Works beyond vehicle exhausts, handy for heating engineers or home repairs on flues and boiler pipework. Keeps one compound useful for several sealing tasks around a workshop.
