What Is Fire Seal 2000?
For years we've been working on a product to repair cracks, pits, or holes in exhaust manifolds, tailpipes, mufflers, or other components subjected to high temperatures while in use. Because replacement parts are often difficult or impossible to find, there is a real need for this type of product in the marketplace.

Fire Seal 2000 is a single-component (no mixing required) ceramic and stainless steel-filled putty that is resistant to fuels, oils, and corrosive materials. After it is fully cured, it will withstand temperatures up to 2000°F Fire Seal 2000 may be applied to rough-surfaced or sandblasted steel, stainless steel, or cast iron. Use a putty knife, small trowel, spatula, or caulking gun to apply.

Curing: Let Fire Seal 2000 dry for 16-24 hours at room temperature. If humidity is excessive, let dry an additional 24 hours. Begin final cure by idling engine for 10-15 minutes at a time. You may sand Fire Seal 2000 after it is fully cured, using a file or medium grit sandpaper Do not use any lubricants for machining, but always use a dust mask to avoid inhaling the sanding dust.

Storage: Store unused material between 45°F and 95°F. Do not permit freezing.

Caution: Be careful to avoid contact with eyes and skin. If product gets into eyes, flush with copious amounts of fresh water. Get prompt medical attention. If swallowed, drink large quantities of milk or water. KEEP OUT OF THE REACH OF CHILDREN.

Surface Preparation
Remove loose rust by abrading parts with a stiff wire brush or sanding tool, Sandblast if parts can be removed from can. Relieve stress in cracked castings by v-grooving the crack and drilling holes through the ends with a 1/8" drill bit. Remove any dirt or oil using lacquer thinner or P0R-l5 Solvent. Burn off residue using a propane torch to improve adhesion and prevent any moisture or oil left in the metal from causing Fire Seal 2000 to blister.

Application Mix contents thoroughly by kneading the pouch. Clip pouch and spread Fire Seal 2000 evenly with a putty knife or spreader. Seal pouch in order to preserve remaining unused material. For pits, cracks, and small holes, a maximum thickness of 3/8" per application is recommended. Make sure to fully cure Fire Seal 2000 if additional applications are required. For holes larger than 3/8" diameter, repairs should be made using a metal screen. First, apply Fire Seal 2000, then form and clamp the screen to the part. Apply a second coating of Fire Seal 2000 to cover the screen.

Curing
Air dry at room temperature for 18-24 hours (up to 48 hours in humid environments), then idle engine or gradually heat repair for 10-15 minutes to fully cure. Note: if bubbling occurs after curing, Fire Seal 2000 was cured too rapidly, or the surface was not adequately cleaned and dried. Correct this by permitting the surface to cool, scrape off the blistered material, and then re-prep the area that bubbled.

Machining
Sand Fire Seal 2000 after it is fully cured, using a file or medium grit sandpaper. Do not use a lubricant for machining. Make sure to wear a dust mask to prevent inhalation of sanding dust.

Storage & Disposal
Store sealed pouches between 45°F and 95°F. Do not allow freezing. Fire Seal 2000 is environmentally safe, water-based, non-flammable, and contains no solvents or volatile organic compounds.
