Gates Engine Crankcase Breather Hose PCV Emission Control

The Gates Engine Crankcase Breather Hose is a PCV (positive crankcase ventilation) hose built for emission control systems. It carries blow-by gases and vapors from the crankcase back to the intake so they can be burned. This helps your engine run cleanly and keeps crankcase pressure under control. You may also see it called a PCV hose, crankcase vent hose, or breather hose.

Key Features:

• Made for the heat, oil vapor, and fuel vapor found in crankcase ventilation systems
• Helps the PCV system reduce emissions and relieve crankcase pressure
• Flexible construction makes routing and installation easier
• Made by Gates, a trusted name in hoses, belts, and engine fluid-transfer components
• Designed to give a secure, reliable seal in the ventilation circuit

A worn, cracked, or oil-soaked breather hose can cause vacuum leaks, rough idle, oil leaks, and sludge buildup. Replacing it with a quality Gates hose helps restore proper crankcase ventilation and supports long-term engine health.
