Timing Chain Tensioner O-Ring – A6519970145

Description

The OEM Timing Chain Tensioner O-Ring (Part Number: A6519970145) is a genuine Mercedes-Benz sealing component designed to create a leak-free seal between the timing chain tensioner and the engine block.

This O-ring prevents engine oil leakage while maintaining correct oil pressure required for proper timing chain tensioner operation. Manufactured to Mercedes-Benz factory specifications using high-quality, oil- and heat-resistant elastomer materials, it ensures durability, precise fitment, and long-term sealing performance.

A worn or damaged O-ring can lead to oil leaks, reduced oil pressure, timing chain noise, and premature wear of timing components. Replacing it with an OEM O-ring ensures reliable sealing and optimal engine timing performance.
