Genuine Mercedes 264 018 25 00 Oil Filler Pipe O-Ring Seal

The Genuine Mercedes-Benz 264 018 25 00 is an OEM replacement O-ring seal designed to maintain a leak-free connection at the oil filler pipe on Mercedes-Benz vehicles equipped with the M264 engine family. This small but critical sealing component prevents engine oil from escaping around the oil filler pipe junction, helping to maintain proper oil levels and keeping the engine bay clean.

As a genuine Mercedes-Benz part, this O-ring is manufactured to the exact material specifications and dimensional tolerances required for a proper factory-fit seal. Aftermarket substitutes may not match the precise durometer, temperature resistance, or cross-section geometry needed for a reliable, long-lasting seal in this application.

Key Features:

• Genuine OEM Mercedes-Benz part — not aftermarket or remanufactured
• Designed for the M264 four-cylinder turbocharged petrol engine platform
• Precision-molded to OEM dimensional tolerances for a factory-correct fit
• Heat and oil-resistant compound to withstand engine operating temperatures
• Direct replacement — no modification required
• Manufacturer Part Number: 264 018 25 00

Replacing a worn or damaged oil filler pipe O-ring at the first sign of seepage helps prevent oil contamination, potential engine damage, and costly repairs. This is a recommended inspection item during routine oil service intervals.
