Verify Your Hone for Optimum Ring Seating

The relationship between the piston ring and the cylinder wall finish is the defining factor in an engine’s oil consumption, blow-by, and overall horsepower. Today’s advanced piston ring materials require very specific cylinder hone surface finishes to seat properly. Total Seal Cylinder Surface Measuring Tools, featuring world-renowned Mitutoyo Profilometers, give you the power to scientifically verify your cylinder wall finish.

These advanced measuring kits allow machinists and engine builders to look beyond the crosshatch and accurately measure the microscopic peaks and valleys of the cylinder wall. By reading crucial surface parameters such as Ra (Average Roughness), Rpk (Peak Height), and Rvk (Valley Depth), you can objectively confirm that your honing process matches the exact specifications required by your piston rings.

Key Benefits for Engine Builders:

• Eliminates Guesswork: Replaces visual inspection with highly accurate, objective data directly from the cylinder wall.
• Ensures Proper Break-In: Verifying the correct surface finish guarantees that piston rings will seat quickly and efficiently, maximizing cylinder pressure.
• Industry-Leading Accuracy: Powered by Mitutoyo electronics, ensuring laboratory-grade precision in a rugged, shop-friendly package.
