Rein Oil Separator Hose

The Rein Oil Separator Hose line is made up of OE-quality crankcase breather hoses (also called PCV hoses or crankcase vent hoses). They are built to replace the original hoses on European vehicles. These hoses carry crankcase gases through the engine's ventilation system, often between the oil separator and the intake or cylinder head cover. They help keep crankcase pressure balanced and help reduce oil leaks.

Key Features:

• Matches original equipment design specifications for a direct-fit replacement
• Made from high-quality materials for durability in the engine bay
• Resists heat, salt, road debris, oil and other contaminants
• Direct-fit design makes installation easier
• Supports the Positive Crankcase Ventilation (PCV) system by returning blow-by gases to the intake, which helps lower emissions

Rein designs its breather hoses to be identical to the OEM part. A worn, cracked or oil-soaked breather hose can cause vacuum leaks, oil seepage and rough running. Replacing it with a Rein hose restores proper crankcase ventilation. Select the specific part number you need from the options on this page.
