Product Name:Valve Grinding CompoundPackage Includes:Coarse 80 Grit Valve Grinding Compound x 125gFine 180 Grit Valve Grinding Compound x 125gProduct FeaturesRemove Stubborn Carbon DepositsRestore Airtight Valve SealDual Grit Design and Meet Diverse NeedsPremium Material and Stable PerformanceWide Compatibility and Multi-purpose UseHow to UseClean the valve, valve seat and cylinder head thoroughly to remove oil, dirt and old carbon deposits.Apply a proper amount of coarse grinding compound evenly on the valve sealing surface.Lap the valve back and forth evenly until the surface is smooth and even.Clean off coarse compound, then apply fine lapping compound for precise mirror polishing.Clean all residual paste completely, reassemble after achieving perfect airtight sealing.PrecautionsFor mechanical repair use only, keep away from skin and eyes.In case of accidental eye contact, rinse immediately with plenty of clean water.Keep out of reach of children and away from food storage areas.Store in a cool dry place, avoid direct sunlight, high temperature and humid environment.Do not mix with other grease or chemical solvents.Q: What is the main function of this valve compound kit?A: This valve lapping and grinding compound is professionally used for valve grinding and cylinder head maintenance. It can effectively remove stubborn carbon deposits, repair worn valve seats, restore engine airtightness and improve power efficiency.Q: What is the difference between coarse and fine grit compound?A: The 80 grit coarse compound is for heavy carbon removal and repairing pitted, worn valve surfaces. The 180 grit fine compound is for fine polishing to form a smooth mirror sealing surface.Q: Is it easy for beginners to use?A: Yes. No professional equipment required. Just apply the paste and lap manually, simple steps make it friendly for both repair shops and home maintenance.Q: Will the compound damage valve parts?A: No. Adopting safe abrasive formula, moderate cutting force, uniform particle size, no scratching on valve seat, cast iron and alloy steel parts, safe for long-term engine maintenance.Q: What engines is this kit suitable for?A: It fits gasoline and diesel engines of cars, motorcycles and industrial machinery. It is also suitable for mechanical surface polishing, carbon cleaning and cylinder head resealing work.

• Carbon Deposits Removal: Valve lapping compound removes stubborn carbon deposits and repairs valve malfunctions caused by them. It penetrates deep into crevices to thoroughly remove carbon buildup without damaging components, effectively improving efficiency, reducing harmful emissions, and enhancing engine throttle response
• Repairing Valve Stem Seals: This process repairs the worn contact surface between the valve and valve seat, restoring a tight, metal-to-metal contact. It restores the engine's compression ratio, power loss problems, and provides a mirror-like seal, thereby optimizing engine performance
• Dual Grit Design:Features dual grit of coarse 80 grit and fine 180 grit, 125g each. Coarse paste removes heavy carbon and repairs worn, pitted valve surfaces; fine paste delivers precise mirror polishing for tight sealing. Dual-grade design covers rough grinding to fine finishing, easily meeting both professional repair and DIY maintenance needs
• Superior Quality and Long-Lasting Durability: This valve grinding paste is made with high-quality abrasives, featuring uniform particle size, strong cutting force, and minimal residue. The optimized formula provides excellent adhesion, prevents splattering, and ensures a stable and controllable grinding process. It is resistant to high temperatures and corrosion, maintaining stable performance even after long-term storage
• Wide Compatibility:This product is compatible with gasoline and diesel engines, suitable for valve maintenance of cars, motorcycles and industrial equipment. It can be safely used on common valve materials like cast iron and alloy steel, and also applies to mechanical surface polishing, carbon deposit removal and cylinder head resealing
