Get the repair moving again when a crack, casting void or damaged fitting makes welding impractical.
Repair metal cracks and casting defects without welding, with strong and high-temperature-resistant adhesion.
- metal cracks
- sand holes in castings
- gas holes in castings
- corrosion-related damage
Restore metal without the welding hassle
Cracks, casting holes and damaged threaded fittings can stop a repair cold. Mix, apply and rebuild the damaged area with strong adhesion designed for demanding metal repairs.
Purpose-Built Repair Features
- Strong Metal Bond
The packaging claim of strong adhesion fits the repairs shown: cracks, casting defects and damaged metal areas. Press the mixed material into sound, prepared metal rather than applying over oil, rust or loose debris.
- Handles Hotter Repairs
High-temperature resistance is one of the stated performance claims. Confirm the part's actual operating conditions first, and always apply to a cool, isolated component.
- Two Parts, One Repair
The purpose-built dual-component cartridge comes with transparent mixing cups and a spatula. That gives you a more deliberate preparation process than improvised two-part mixing.
- Seals Beyond Surface Cracks
Use cases include pipe cracks, sand holes, gas holes, corrosion-related damage and threaded metal components. The wide application claim makes it useful across garage, plumbing and maintenance work.

- 3.38 fl ozUsable cartridge volume
- ~200 daysDaily-use longevity hint
Mix, Apply, Restore
- 1Isolate The Part
Remove the component from active heat, pressure, water flow or movement. Work only on a cool, dry and accessible repair area.
- 2Prepare Sound Metal
Remove oil, rust, loose debris and other contamination. Expose a firm surrounding surface so the adhesive can contact sound metal.
- 3Mix The Components
Use the transparent cup and included spatula to mix the two components thoroughly according to the product directions.
- 4Fill And Shape
Press the gray adhesive into the crack, hole or damaged fitting area. Shape the repair while working carefully around the surrounding metal.
- 5Inspect Before Service
Allow the repair to set according to the product directions, then inspect the bond and confirm that the application suits the part's conditions.

A Repair Path When Welding Is Not Practical
- 1The Repair That Cannot Wait
A small crack, casting void or damaged fitting can hold up an entire repair. Left exposed, the defect can invite leaks, corrosion and more pressure on the surrounding part.
- 2A Welder Is Not Always Practical
Awkward access, missing equipment and added heat can make welding the wrong first move for a small repair. A metal repair epoxy putty gives you another route when the part is isolated and suitable for adhesive restoration.
- 3Mix In, Build Back
The dual-component cartridge, transparent cups and mixing spatula keep preparation clear. Mix the two parts, work the gray adhesive into the prepared damage and shape the repair with control.
- 4Back To The Workbench
The damaged area is filled and sealed so the repair can move forward. Use the material with a careful check of the part, load, temperature, pressure and surface condition before returning it to service.

Questions and answers
No. It is a practical welding alternative for suitable cracks, casting defects and damaged fittings when welding access is limited. Adhesive repairs depend on the part, load, temperature, pressure and surface condition, so use professional repair or welding where the application demands it.
Those are stated applications for the product. Clean away loose material, expose sound surrounding metal and press the mixed adhesive into the defect. Check the repaired part carefully before putting it back into service.
Yes, damaged threaded components are among the listed applications. Remove contamination, apply the mixed adhesive around the damaged area and keep the fitting out of service until the repair has properly set.
Good waterproof performance is a stated product claim. The surface still needs to be clean and dry during application, and the repair must be suitable for the pressure and water conditions of the part.
Use the included transparent mixing cups and spatula. Dispense the two components, mix them thoroughly according to the product directions and apply the gray adhesive to prepared metal. Do not guess the ratio or leave unmixed material.
No. Isolate, depressurize and cool the part before application. High-temperature resistance refers to the stated property of the finished adhesive, not permission to apply it while the part is hot or under active pressure.
