Holts HL2R Exhaust Repair Paste - High Temperature Heat-Resi

Holts Firegum Exhaust Repair Paste

Holts Firegum is the professional’s choice for sealing exhaust joints and repairing small holes. This high-temperature paste is specifically formulated to expand and set as it heats up, creating a gas-tight, permanent seal that resists extreme heat, constant vibration, and moisture. It is essential for use during the assembly of new exhaust systems to ensure a 100% leak-free fitment and prevent "blowing" joints. The easy-to-apply formula fills gaps in flanged joints and sleeves, helping vehicles pass MOT exhaust emission and noise tests by ensuring the system is fully sealed from manifold to tailpipe.

Automotive Industry Suggested Uses:

• Exhaust Assembly: Smearing on sleeve joints and flanges during new exhaust fitting to ensure a professional, gas-tight seal.
• Minor Leak Repair: Patching small holes in mufflers and resonators to prevent carbon monoxide ingress and noise failures.
