NOK 49441689 Pcv Valve Grommet

The NOK 49441689 is a replacement PCV (Positive Crankcase Ventilation) valve grommet designed to provide a secure, leak-free seal between the PCV valve and the valve cover or intake manifold. This small but critical component prevents oil leaks and ensures proper crankcase ventilation system operation.

Key Features:

• Engineered for precise fit and reliable sealing performance
• Durable rubber construction resists oil, heat, and deterioration
• Prevents vacuum leaks that can affect engine performance
• Direct replacement for worn or damaged OEM grommets
• Essential component for maintaining proper PCV system function

Over time, PCV valve grommets can become brittle and crack due to exposure to engine heat and oil, leading to vacuum leaks, rough idle, and increased oil consumption. Replacing a degraded grommet restores proper system operation and prevents these common issues.
