Special Lapping Paste (oil-soluble)

An oil-soluble lapping paste provides greater lubrication and therefore produces a finer result.
Unlike water-soluble pastes, there is no risk of corrosion. You can easily remove it with oil, solvent, or R16.

It is suitable for hardened steel, aluminum, and plastics. It enables precise grinding and ensures an even result.
Choose the right grain size for optimal results.

Apply a thin layer to the metal surface. Use a brush or spatula for this. Choose the grain size to suit the material and the desired result. Move the valve and seat against each other. Check the sealing surface regularly for an even grinding pattern.
Especially with larger valves, you can better control the fit with Engineer’s Marking Paste. If the color impression on the counterpart is irregular, you can improve the result. Simply repeat the lapping process.

Yes, a water-soluble version is available on request. It is easier to remove and is an alternative if there is no risk of corrosion.

Store the product in a cool, dry place. Avoid direct sunlight and extreme temperatures.
If some oil accumulates on the surface of the paste, you can simply stir it in.
