Gates Crankcase Ventilation Emission Control Hose

The Gates Crankcase Ventilation Emission Control Hose line, also sold as PCV hose or crankcase breather hose, is engineered to carry blow-by gases and oil vapors from the engine crankcase back to the intake system. This keeps the positive crankcase ventilation (PCV) system working as designed and supports emission control.

Key Features:

• Made to resist oil, oil vapor, heat, and the hydrocarbon exposure found in crankcase ventilation circuits
• Flexible construction helps the hose route and seal properly in tight engine bay spaces
• Built to hold up to the heat cycling and vibration of daily driving
• Helps keep crankcase pressure balanced and limits oil leaks and vacuum leaks
• Backed by Gates, a respected name in belts, hoses, and fluid transfer products with OE-level quality standards

A worn, cracked, or oil-soaked ventilation hose can cause rough idle, oil consumption, sludge buildup, and increased emissions. Replacing it with a Gates crankcase ventilation hose helps restore proper PCV operation and dependable engine performance. Select the correct child item for your application.
