A Crankcase Ventilation Breather Hose endures exposure to elevated temperatures, oil vapors, and engine fluids without compromising its structural integrity. The breather hose provides a conduit for these gases to be vented from the crankcase and directed to the appropriate disposal point the intake manifold or the atmosphere. As the engine operates, blow-by gases, which consist of unburned hydrocarbons, moisture, and other byproducts of combustion, accumulate in the crankcase.Attributes:• Prevent the accumulation of pressure that could lead to oil leaks• The hose's inner diameter gradually changes from 19mm to 34.5mmApplications:A Crankcase Ventilation Breather Hose facilitates the safe and efficient disposal of fumes and gases that accumulate within the engine's crankcase during the combustion process.
