471-9912: Air Inlet Heater Hose

The Closed Crankcase Breather Heater Line Hose routes blow-by gases, a mixture of air and unburned fuel that escapes piston rings in the engine, away from the environment and towards the intake system for proper handling. By redirecting unburned fuel vapors back into the engine for re-burning, this hose plays a role in minimizing harmful emissions and promoting a cleaner environment. Attributes: • Withstands the high temperatures of engine operation. • Resist degradation from engine oil vapors present in the blow-by gases. • Maintains flexibility to accommodate engine vibrations without leaking. Applications: The Closed Crankcase Breather Heater Line Hose is positioned near a heat source to ensure the blow-by gases are warm enough for proper processing in the intake system.
