Gates Engine Crankcase Breather Emission Control Hose

The Gates Engine Crankcase Breather Emission Control Hose, also called a PCV hose or crankcase ventilation hose, carries blow-by gases and vapors from the engine crankcase back to the intake system. This helps the engine's emission control system work as designed. Gates is a long-established maker of belts, hoses, and fluid-transfer products, and it supplies both OE and aftermarket markets.

Key Features:

• Designed to handle the heat, oil vapor, and fuel-vapor exposure found in crankcase ventilation systems
• Made from oil-resistant hose materials to resist swelling, cracking, and hardening over time
• Helps keep the positive crankcase ventilation (PCV) system sealed and working properly
• Helps reduce oil leaks, vacuum leaks, and rough idle caused by deteriorated breather hoses
• Built to a consistent standard for fit, flexibility, and durability

Replacing a worn or brittle crankcase breather hose helps maintain correct engine ventilation, supports emissions performance, and protects the engine from sludge buildup and pressure-related leaks. Choose the specific part number that matches your application.
