Genuine Breather Tube PCV Hose

The Genuine Breather Tube PCV Hose line is made up of OEM-style crankcase breather hoses, also called PCV hoses or breather tubes. These hoses are part of the positive crankcase ventilation system. They carry blow-by gases and vapors out of the engine crankcase and route them back toward the intake to be burned. This helps control crankcase pressure and reduce emissions.

Key Features:

• Engine crankcase breather hose designed to carry PCV system vapors
• Helps relieve crankcase pressure and keep the ventilation circuit working as designed
• Genuine OEM-type construction made for the temperatures and oil vapors found in the engine bay
• Direct-replacement design for a worn, cracked, brittle, or leaking breather tube

Replacing an aged PCV or breather hose can help prevent vacuum leaks, oil seepage, rough idle, and other problems linked to a failing crankcase ventilation system. Choose the individual part number that matches your application.
