Description
Product Overview
After long-term use, the metal gasket at the cylinder head of the injector will be deformed under pressure and the rubber inner layer will age, resulting in high-pressure fuel leakage and unstable rail pressure. The nozzle without protection during storage and transportation is prone to being knocked and damaged, causing the atomization to fail. This kit comes with sealing gaskets and protective plugs, which can be used simultaneously during major injector repairs and replacements, improving assembly sealing performance, reducing accessory storage losses, and is suitable for maintenance of light-duty diesel vehicles and small construction machinery common rail injectors.
Unique Core Features of the Individual Product
Embedded blue rubber composite metal gasket, double-layer sealing for high pressure resistance
The gasket is made by integrating a metal outer ring and an oil-resistant blue rubber inner layer through a single-plate stamping process. The metal layer withstands the assembly compression force, while the rubber layer fills the tiny gaps and can withstand common rail high pressure. It is resistant to high-temperature diesel immersion and does not harden or deform easily, preventing oil leakage and pressure relief at the cylinder head installation position.
Multi-size gasket combinations cover all sealing points of a single injector
The kit comes with two sizes of sealing gaskets, suitable for the injector's intake port and the cylinder head installation surface for sealing. With one set, maintenance does not require separate distinction of size and separate purchase of scattered parts.
Red soft rubber oil nozzle protection plug, buffering and collision prevention
Two red elastic plastic protective caps are placed on the tip of the injector before installation. During storage and transportation, they isolate collisions and dust and impurities, avoiding damage to the precise micro-pore injector nozzle and clogging, and reducing installation faults.
Integrated stamping gasket, high flatness and tight fit
The gasket is stamped without burrs and has uniform thickness. After assembly, it fits perfectly with the cylinder head and the injector base, without any local pressure leakage, ensuring stable injector operation.
Oil-resistant and aging-resistant rubber material, extending sealing usage period
The inner blue rubber uses raw materials resistant to diesel and high temperatures, which do not crack or shrink easily in the high-temperature cabin environment and reduce short-term rework leakage. Applicable scenarios
Suitable for the disassembly, assembly and overhaul of electronic fuel injection injectors for light-duty diesel pickup trucks, box-type light goods, small excavators, and agricultural machinery. It is applicable for urban commuting, field and construction sites with high and low temperatures, and dusty conditions under light loads.
