Frequently Asked Questions
How should I use lapping paste on nozzle seats?
Apply a small amount of paste to the nozzle seat or valve face, then rotate the matching tool (e.g., a lapping stick or drill) with a back-and-forth rocking motion. Continue until a uniform, clean surface is achieved. Clean thoroughly before assembly.
What grades are available?
We offer both coarse and fine grades. Coarse (120 grit) is ideal for removing deep pitting or scratches, while fine (400 grit) is used for final polishing and achieving a precise seal.
Can this paste be used on exhaust valves?
Yes, it is suitable for fuel injectors, nozzle seats, and exhaust valve seats. Always ensure the material is compatible with the valve and seat materials.
Is this product safe for use on chrome-plated components?
This paste is designed for metal-to-metal lapping and may remove plating. Use only on bare steel or cast iron surfaces. For chrome or zinc-coated parts, consult the engine manufacturer.
