Description
Product Overview
The electronically controlled fuel injectors are constantly exposed to high temperatures in the engine compartment, high-pressure fuel, and engine oil, causing the original factory sealing rings to harden, crack, and fail in compression rebound, resulting in high-pressure fuel leakage, continuous fluctuations in the rail pressure, and causing engine power loss, increased fuel consumption, and black smoke emission. This complete set of sealing repair kit integrates all the sealing components for the fuel injectors, eliminating the need for separate and scattered purchase of various rubber rings and gaskets. It is suitable for the disassembly and repair of corresponding model fuel injectors and effectively blocks oil leakage, stabilizing the system rail pressure after assembly.
Unique core advantages of this kit
One set of fully equipped sealing components for all points, completing the major repair of a single fuel injector in one step
The kit includes large-sized black O-rings, small-sized black O-rings, green oil-resistant high-pressure sealing rings, purple copper sealing gaskets, and white filter plugs, covering all sealing points of the fuel injector valve body, fuel injector nozzle, and installation flange. A single purchase can complete the sealing replacement of a single fuel injector, eliminating the hassle of multiple small-item purchases.
Multi-layer oil-resistant rubber O-rings, resistant to high pressure and high temperature, not prone to aging
All-sized rubber sealing rings are made of oil-resistant fluororubber material, capable of withstanding long-term immersion in diesel and engine oil, suitable for alternating high and low temperatures in the engine compartment. They have stable rebound under high-pressure conditions, not prone to hardening or cracking, and effectively prevent fuel leakage and pressure relief.
Purple copper metal sealing gaskets, with strong high-pressure sealing performance
The accompanying purple copper gaskets are soft in texture and can fully adhere to the assembly contact surface after tightening, filling small gaps, and preventing leakage under the impact of high-pressure fuel from the fuel injector without leakage. Compared to ordinary rubber gaskets, they have stronger pressure resistance.
The accompanying white filter protection plug, protecting the precise spray holes during maintenance and assembly
The kit comes with plastic protective plugs. During the disassembly and repair of the fuel injector, the front spray hole can be blocked to prevent dust and impurities from entering the internal precision valve components and avoid clogging of the spray holes and poor atomization after maintenance.
Precise size standardization, no assembly deviation, no need for grinding
All rubber rings, gasket diameters, and thicknesses are strictly matched with the corresponding model fuel injector. Installation and disassembly can be directly aligned and installed without problems of loose leakage or tight assembly and jamming, reducing the difficulty of maintenance and adjustment.
