3. Technical Principle

Typically made from fuel-resistant specialty rubber, this O-ring is seated in a groove on the injector. When the injector is installed and tightened, the O-ring is compressed, creating elastic deformation that forms a tight, leak-free static seal between metal components. It is engineered to withstand high fuel pressure and temperature fluctuations in the engine bay.

4. Features

• Precise Fit: Engineered to the exact specifications of M271 engine injectors for perfect seating.

• Premium Material: Often constructed from high-performance materials like Fluoroelastomer (FKM), offering excellent resistance to fuel, high temperatures, and aging.

• Precision Manufacturing: Ensures exact dimensions and roundness for uniform sealing pressure upon installation, preventing leaks.

• Set Offering: Commonly sold in multi-piece sets, allowing for the convenient replacement of all seals at once.

5. Benefits

• Prevents Leaks: Effectively seals fuel, preventing hazards and waste, while ensuring a clean and safe engine compartment.

• Maintains Fuel Pressure: Ensures the fuel system maintains correct pressure, resulting in smooth engine power and optimal fuel economy.

• Prevents Air Intrusion: Stops air from entering the fuel system, which can cause hard starting, engine hesitation, or power loss.

• High Reliability: High-quality materials ensure long service life, reducing repeat repairs caused by component failure.

6. Service

• Backed by OEM-quality assurance or warranties that meet strict industry standards.

• Suitable for professional automotive repair shops, 4S stores, and experienced DIY enthusiasts.
