Description
### Product Overview
The compression nuts of the fuel injectors are installed on the outer side of the fuel injectors. They rely on the pre-tightening force of the threads to firmly press the fuel injectors onto the main body of the fuel injectors, ensuring a sealed joint surface and preventing high-pressure fuel leakage. Under conditions of repeated disassembly, high-temperature vibration and impact, the threads may slip and the end faces may deform, resulting in insufficient compression force and fuel leakage or misalignment of the fuel injection angle. This product has standardized production of internal thread dimensions, hexagonal shapes and pressure-bearing end faces. When disassembling and inspecting the fuel injectors and replacing the fuel injectors, this product is also replaced simultaneously, suitable for maintenance of common rail engines of diesel construction machinery and heavy-duty freight vehicles.
Core advantages of the product
1. **High-strength alloy steel substrate, high torque without cracking or thread slippage**
The pressure cap is precisely machined from high-quality alloy steel and undergoes overall quenching and tempering treatment. It can withstand the standard assembly torque without cracking or thread wear, and is resistant to continuous high-temperature vibration in the engine environment.
2. **Precisely machined internal threads, smooth engagement and uniform force distribution**
The threads are precisely rolled and formed, with regular tooth shapes. The insertion process is smooth, and the thread load distribution is balanced after tightening, making it less likely to loosen over a long-term operation.
3. **Flat pressure-bearing end face, uniform pressure on the fuel injector to prevent leakage**
The bottom pressure-bearing end face is precisely ground to high precision, with stable flatness. After tightening, it can uniformly apply pressure to the fuel injector flange, avoiding local stress concentration that causes sealing leakage.
4. **Standard hexagonal shape, compatible with common disassembly and assembly tools**
The external hexagonal specifications are uniform. Regular socket tools can complete disassembly and assembly, making maintenance operations convenient and eliminating the need for special and unique tools.
5. **Resistant to high and low temperature alternating conditions, suitable for complex working environments**
The material has excellent thermal stability. It is not prone to deformation under alternating high-temperature and heavy-load conditions at low temperatures and high temperatures. It maintains the pre-tightening pressure continuously and stably.
6. **Each batch undergoes dimensional inspection, ensuring consistent parameters of individual pieces**
Each batch of products is sampled and inspected for inner diameter, thread accuracy, and end face flatness. The specifications are uniform, and the stability of large-scale maintenance spare parts assembly is stronger.
