URO 30720101 Crankcase Breather Hose for PCV Valve

The URO 30720101 is a crankcase breather hose designed to connect at the PCV (Positive Crankcase Ventilation) valve. This hose is a critical component of the engine's emissions control system, allowing crankcase gases to be routed back into the intake manifold for proper combustion rather than being vented to the atmosphere.

Key Features:

• Direct replacement for worn or damaged OEM crankcase breather hose
• Connects at the PCV valve location for proper ventilation system operation
• Manufactured to meet or exceed original equipment specifications
• Helps maintain proper crankcase pressure and prevents oil leaks
• Essential for maintaining emissions compliance and engine performance

Over time, breather hoses can crack, become brittle, or develop leaks due to constant exposure to heat and oil vapors. Replacing a deteriorated breather hose restores proper PCV system function, prevents vacuum leaks that can cause rough idle or check engine lights, and ensures crankcase gases are properly managed.
