Description
Product Overview
The conical copper gasket is installed at the contact position between the injector nozzle and the cylinder head. It relies on the excellent ductility of copper to fill the installation gap after tightening the injector, preventing the high-temperature gas in the combustion chamber from flowing back, and blocking the leakage of high-pressure fuel through the assembly gap. Under the long-term high-temperature combustion and alternating hot and cold working conditions of the engine, the old gasket may become hardened, lose its compression rebound performance, and develop local erosion gaps, causing gas to enter the oil circuit, fuel leakage, and severe carbon deposits on the cylinder head. This product has a unified standard for the taper, inner and outer diameters, and thickness. By replacing the gasket simultaneously during the disassembly and assembly of the injector, the leakage and gas backflow faults can be eliminated. It is suitable for the maintenance of light trucks, pickup trucks, construction machinery, heavy trucks, and electric control common rail / mechanical direct injection injectors for heavy-duty trucks.
Core Advantages of the Single Item
High-purity integrated stamping copper material with good ductility for sealing
The high-purity copper sheet is stamped into one piece, with a soft texture and good compression rebound performance. When tightening the injector, it evenly fills the gap between the cylinder head and the nozzle, and is not prone to hardening and cracking under high-temperature and high-pressure conditions. It can maintain the sealing performance for a long time.
Gated conical step gradual contact surface, perfectly matching the installation slope of the injector nozzle
The double-layer stepped conical structure has an arc shape that precisely matches the injector nozzle and the cylinder head mounting seat, increasing the sealing contact area and eliminating local sealing gaps, completely blocking the backflow of gas and fuel leakage.
Smooth and precise central through-hole, suitable for the outer diameter of the nozzle without obstruction
The central through-hole is precisely machined, with a smooth inner wall and no burrs, maintaining an appropriate gap with the outer diameter of the injector nozzle, allowing it to smoothly fit when disassembling the injector, without scratching the precise atomization working surface of the nozzle.
High-temperature heat-conducting buffer, protecting the injector body from high temperatures
The copper has balanced heat-conducting performance, which can buffer the instantaneous high temperature in the combustion chamber, reducing the direct transmission of high temperatures to the injector valve body, delaying the aging of internal sealing components and coils, and extending the overall service life of the injector.
No burrs in stamping process, no metal debris or impurities during assembly
After overall stamping, the edges are deburred and finely processed, without metal fly-edges or debris. When replacing and installing, impurities will not fall into the cylinder or the oil circuit, avoiding oil circuit blockage and cylinder wear.
Single-piece compression sealing for factory inspection, uniform and stable dimensions in the same batch
Samples of each batch of gaskets are tested for compression rebound and high-temperature sealing. The tolerance for thickness and taper is strictly controlled. After assembly, no additional grinding or adjustment is required, making maintenance and replacement convenient and efficient.
