High-temperature metal filler
J-B Weld 37901 Extreme Heat is a water-based metallic paste rated for 2400 F and 1300 C. It bonds iron, steel and other metals in exhaust manifolds, mufflers, grills and furnaces. The grey compound contains no solvents or VOCs and is non-flammable in its uncured state.
Simple application with long cure
The paste is applied directly from the 3 oz carded tube and sets in about 1 hour at room temperature. Full cure requires 24 hours before the repair can be drilled, machined or sanded. Rushing the cure or skipping surface cleaning are the most common causes of bond failure.
Limited to static high-heat metal joints
This filler is designed for stationary metal parts that reach extreme temperatures. It will not adhere to plastics, rubbers or flexible substrates. Moving components, pressurised vessels beyond the rated heat range or applications requiring electrical insulation fall outside its intended use.

Questions about this item
How can I confirm the repair has fully cured and reached its 2400 F temperature rating?
After the 24-hour cure time, the grey metallic paste becomes hard enough to be drilled, machined or sanded, indicating it has developed full strength for high-heat applications.
What comes in the package and do I need any extra tools or mixing components?
The carded package contains one 3 oz unit of the water-based metallic paste; no separate hardener or mixing tools are required, though sandpaper or a file may be useful for finishing after curing.
Is the 3 oz size sufficient for sealing a cracked exhaust manifold or should I buy multiple units?
The 3 oz tube is designed for small cracks, gaps, seam connections or holes in components such as exhaust manifolds, mufflers or pipe connections; larger repairs may need more than one unit.
