Gates Engine Crankcase Breather Hose

The Gates Engine Crankcase Breather Hose is a molded rubber hose for the positive crankcase ventilation (PCV) system. It carries blow-by gases and vapors from the crankcase back to the intake so they can be burned off. Gates is a long-established maker of belts, hoses and fluid-transfer products, and it supplies both the OE and aftermarket markets. Also called a PCV hose, crankcase vent hose or breather hose, this part helps keep the engine's ventilation system working as designed.

Key Features:

• Made from rubber compounds designed to resist oil, heat, and engine-bay vapors
• Built for the ongoing exposure to crankcase gases and oil mist found in PCV systems
• Molded shapes and construction are meant to match the original hose for a proper fit
• Helps reduce crankcase pressure buildup and supports emissions control
• Replaces cracked, hardened, collapsed, or oil-soaked hoses that can cause vacuum leaks, oil leaks, or rough running

Replacing a worn breather hose helps protect gaskets and seals from excess crankcase pressure and keeps the engine running smoothly. Gates quality control and testing back each hose in the line.
