• Constructed from high-quality aluminium for strength and heat resistance
• Inside diameter of 28.2 mm and outside diameter of 32.5 mm for exact fitment
• 1.0 mm thickness providing optimal sealing without deformation
• A-shape design tailored for effective sealing in prechamber applications
• Compatible with multiple Mercedes-Benz diesel models including 300D, 300SD, 300SDL, 300TD, 350SD, 350SDL, E300, and S350

Detailed Product Description

The Elring 446.950 seal ring is manufactured from aluminium, a material chosen for its excellent thermal conductivity and resistance to corrosion, which is critical in diesel fuel injection systems. The precise dimensions—28.2 mm inside diameter, 32.5 mm outside diameter, and 1.0 mm thickness—ensure a secure and leak-free seal within the prechamber. Its A-shape profile is designed to maintain consistent pressure and prevent fuel or combustion gas leaks, contributing to engine efficiency and longevity. This part is engineered to meet the specifications required by Mercedes-Benz diesel engines, making it a suitable replacement for the prechamber seal ring in models such as the 300D and 350SDL.

Applications and Problem Solving

• Prevents fuel leakage in diesel fuel injection prechambers
• Maintains combustion chamber pressure for efficient engine performance
• Reduces risk of exhaust gas leaks that can cause engine misfires
• Helps avoid premature wear of injection components due to improper sealing
• Supports consistent engine starting and smooth operation in Mercedes-Benz diesel models

Installation Notes and Tips

When installing the Elring 446.950 seal ring, ensure the prechamber surface is clean and free of debris to achieve optimal sealing. Handle the aluminium ring carefully to avoid bending or distortion. It is recommended to verify the correct orientation of the A-shape profile during installation to maintain proper sealing function. Use appropriate torque specifications for the prechamber assembly to prevent damage to the seal ring.
