Introduction of engine crankcase breather hose：
Engine crankcase breather hose is a key component in the ventilation system of the crankcase of an automobile engine. Engine crankcase breather hose is responsible for directing the gases generated in the crankcase (such as unburned fuel vapor and exhaust gas) to the intake manifold for secondary combustion. This helps reduce emissions, prevent excessive crankcase pressure and oil leakage. If the hose is damaged (such as broken or clogged), crank vent hose may cause the engine to idle unsteadily, increase oil consumption, or the failure light will light up crank vent hose.
The advantages of our production of crankcase vent hose for BMW：
1. In the manufacturing process of crankcase vent hose for BMW, we crank vent hose generally use fluorine rubber (FKM) or high-performance silicone material, which can withstand extreme temperature ranges from -40℃ to 200℃, so our crankcase vent hose for BMW material is much better than ordinary rubber tube (the latter is easy to soften and crack). At the same time, crankcase vent hose for BMW is resistant to corrosion of engine oil, fuel oil and acidic channeling gas, and does not deform or deteriorate during long-term use, greatly extending product life and reducing maintenance requirements.
2. We have a low permeability structure in the design of crankcase vent hose for BMW, which effectively reduces engine oil vapor emissions. Crankcase vent hose for BMW helps us meet national six emission standards. The crankcase vent hose for BMW we produce, combined with strict sealing technology, can prevent air leakage and gas leakage, and avoid engine jitter or performance degradation.
3. Our crankcase ventilation hose fully complies with the EU REACH/ROHS standard and has no plasticizer volatilization (protecting the air quality in the car). At the same time, our crank vent hose crankcase vent hose reduces environmental pollution through a low-permeability design. This not only supports sustainable development, but also helps customers cope with global environmental regulations.
4. We insist on special mold-opening manufacturing for special cars, so our crankcase ventilation hose perfectly matches the original plug position, and there is no need to heat and soften during installation (elastic memory material ensures fast and easy operation). This simplifies the maintenance process, reduces the risk of installation errors, and improves user friendliness.

FAQ：
Q1: Why can crank vent hose crankcase ventilation hose withstand high temperatures of 200℃? Why can't ordinary tubes do it?
A1: Our crank vent hose crankcase ventilation hose uses aerospace-grade fluorine rubber (FKM) material, and the heat resistance of the molecular structure is 3 times higher than that of natural rubber.
Q2: Does this crankcase ventilation hose really not need to be heated? What problems can be caused by installation errors?
A2: Our crank vent hose elastic memory material remains flexible at -40℃, and it is designed for in-line anti-reverse installation. Incorrect installation can easily trigger the engine fault code P0171 (air leakage), and the error rate of this product is <0.1%.
Q3: How does crank vent hose crank vent hose crankcase ventilation hose's REACH/ROHS certification guarantee the air quality in the car?
A3: The detection limit of plasticizer/heavy metal is <0.01ppm (almost zero volatilization), and it has passed the highest standard of odor testing of OEMs (grade≤3.0) to eliminate "new car odor".
Q4: How to verify the 8-year life span? Is the replacement cost of crank vent hose higher?
A4: Simulate 150,000 kilometers based on SAE J20 accelerated aging standard. Although the unit price is 30% higher, the frequency of maintenance is reduced by 70%.
