How Rocker Arm Assemblies Work
Multi-layer metal design for good sealing:
Combustion Sealing: Takes cylinder pressure, stops hot gas blowing out.
Fluid Isolation: Keeps cooling water and oil apart, no mixing.
Heat Resistance: Handles high engine heat, won't turn soft easily.
Engine Protection: Keeps compression steady. Broken gasket leads to power loss, white smoke and overheating.

Quality Inspection
Our inspection process covers:
Dimension Check: All critical dimensions (hole positions, bore sizes, overall profile) are measured with precision instruments to guarantee a perfect 1:1 fit.
Flatness Test: Each gasket is inspected for surface flatness, ensuring even sealing pressure across the entire combustion area.
Compression & Sealing Test: Samples from each batch undergo compression testing to verify the sealing layer performs reliably under high cylinder pressure and temperature.
Material Verification: Raw materials are checked for thickness, metal composition and coating quality before production.
