jinLongvia 7703062072Fuel Injector Copper Gasket Seal Kit, 4 Pieces

• High-Purity Copper Construction: Each sealing washer is stamped from solid copper, providing excellent thermal conductivity and the crushing compliance needed to create a perfect, leak-free seal between the injector and cylinder head.
• Complete 4-Piece Kit: Contains four injector base gaskets and the matching viton or silicone O-rings, enough to service a full set of injectors in one package and eliminate multiple trips to the parts store.
• Stops Fuel and Compression Leaks: Effectively seals against high-pressure combustion gases and diesel/gasoline fuel seepage, curing hard starts, rough idle, and the “chuffing” sound that comes from a failed injector seal.
• Direct Drop-In Fit: Manufactured to match the factory seat angle and diameter for numbers7703062072, ensuring the injector sits at the correct depth for proper spray pattern and atomization.
• Professional-Grade Reliability: The copper gaskets are annealed to the correct hardness, preventing over-crushing while still forming an airtight seal; ideal for both injector cleaning services and complete engine overhauls.
