Visbella Exhaust System Sealant is a professional exhaust system sealant engineered to solve exhaust leaks and ensure airtight seals for high-temperature applications. This thick, non-slumping paste is a game-changer for automotive repair, curing through water evaporation and further hardening with heat—creating an impenetrable barrier against noxious fumes.

With a high-temperature resistance of 1100°C (2012°F), Visbella Exhaust System Sealant thrives in the hottest parts of the exhaust system. It maintains its seal even under extreme engine heat, preventing leaks and ensuring long-term durability.
The thick, non-slumping paste consistency allows for easy application—staying in place on vertical and horizontal surfaces without running or dripping. This ensures precise coverage over holes, gaps, and joints for a perfect seal.
Once cured, the sealant forms an airtight barrier that blocks all harmful noxious fumes from escaping the exhaust system. This enhances safety for both the vehicle’s occupants and the environment.
The sealant cures initially through water evaporation and further hardens when exposed to heat (e.g., engine operation). This dual curing process ensures a strong, flexible bond that adapts to the exhaust system’s thermal expansion and contraction.
Ideal for sealing joints, holes, and gaps in mufflers, tailpipes, catalytic converters, exhaust manifolds, and downpipes. It’s compatible with all exhaust system materials, including steel, aluminum, and stainless steel.
Perfect for DIY enthusiasts repairing leaky exhausts at home or professionals installing new exhaust components. It eliminates the need for expensive welding in minor repair cases, saving time and money.
Works effectively on heavy-duty vehicles like trucks, buses, and construction equipment—withstanding the intense heat and vibration of frequent, long-distance use.
