Description
Product Overview
A double-layer copper gasket is installed at the contact position between the fuel injector and the cylinder head. Due to the excellent ductility of copper, after tightening the fuel injector, it can fully fill the installation gap, preventing the high-temperature gas in the combustion chamber from flowing back outward, and blocking the leakage of high-pressure fuel through the assembly gap. Under the long-term cold and hot cycling and continuous high-temperature combustion conditions of the engine, single-layer thin gaskets are prone to compression failure and erosion damage. The double-layer thickened structure has better rebound performance and a longer service life. This product has a unified standard for inner and outer diameters, 1.5mm standard thickness, and internal tooth positioning groove dimensions. By replacing the gasket synchronously when disassembling the fuel injector, it can eliminate the problems of gas leakage and oil seepage. It is suitable for maintenance of various direct injection / common rail diesel engines of light trucks, pickup trucks, construction machinery, and heavy trucks.
Core Advantages of the Single Product
Double-layer composite high-purity copper sheet is stamped with strong ductility, ensuring long-lasting sealing rebound
The double-layer integrated copper material has a soft texture and better compression rebound performance than single-layer gaskets. It will not quickly harden and fail under long-term alternating high and low temperatures. After tightening, it can evenly fill the gap between the cylinder head and the fuel injector, maintaining long-term sealing effect.
Standard 1.5mm fixed total thickness, precise and uniform assembly fit
Strict control of the 1.5mm overall thickness, with minimal batch-to-batch thickness error. After installation, the compression stroke of the fuel injector is standard, and there will be no problems of excessive tightness causing damage to the nozzle or insufficient tightness resulting in poor sealing.
Internal ring with positioning teeth groove, no offset during assembly
The inner ring is equipped with multiple groups of positioning teeth grooves. When fitted around the outer diameter of the fuel injector, it automatically limits the position, preventing the gasket from rotating and running off, ensuring that the sealing surface is fully in contact and eliminating gas leakage through local gaps.
Balanced heat conduction and insulation structure, buffering high temperature to protect the fuel injector assembly
The copper has balanced heat conduction performance, buffering the instantaneous high temperature of the combustion chamber, reducing direct heat conduction to the fuel injector valve body, delaying the aging of internal sealing components and valve cores, and extending the overall service life of the fuel injector.
Edges without burrs are precisely processed, and there is no metal impurities contaminating the oil circuit and cylinder
After stamping, the entire edge is deburred, without metal fly edges or debris. When replacing and installing, impurities will not fall into the oil circuit or cylinder, avoiding oil circuit blockage and abnormal wear in the cylinder.
Batch high-temperature compression durability inspection, stable performance in the same batch
Samples of the gaskets are taken from each batch for high-temperature cycling and compression rebound sealing tests. The thickness and ductility parameters are unified. No additional grinding and adjustment is required for assembly, making maintenance and replacement convenient and efficient. List of Accessories
