Gates Crankcase Breather Hose

Gates Engine Crankcase Breather Hoses, also called PCV hoses or emission control hoses, are OE-exact replacement hoses for the crankcase ventilation system. They carry crankcase gases between components such as the PCV valve, the oil separator and the intake. This helps regulate crankcase pressure, reduce emissions and keep the engine running efficiently.

Key Features:

• OE-exact design: Molded to match the original hose shape, routing and connection style for direct replacement.
• Durable construction: Made from rubber or a plastic and rubber combination to handle engine-bay conditions.
• Molded connections: Push-in or clip-on ends give a secure, factory-style connection.
• Emission system support: Restores the crankcase ventilation path so harmful gases are routed back to the engine and burned, not vented.
• Brand quality: Gates is a well-known maker of hoses and belts for original equipment and replacement use.

A worn, cracked or collapsed breather hose can cause vacuum leaks, rough idle, oil leaks and emission problems. Replacing it with a Gates molded hose helps restore proper crankcase ventilation. Choose the child item that matches your application.
