Introduction to crankcase breather hose:
Crankcase breather hose is a key component in the ventilation system of the crankcase of an automobile engine. Crankcase breather hose(Ventilation tubing) 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 crankcase ventilation tube helps reduce emissions, prevent excessive crankcase pressure and oil leakage. If the hose is damaged (such as broken or clogged), crankcase ventilation hose may cause the engine to idle unsteadily, increase oil consumption, or the failure light will light up.
Crankcase breather hose installation method:
The purpose of automotive crankcase ventilation breather hose is to manage and control the flow of gas inside the crankcase during engine operation. Specifically, crankcase ventilation hose has the following important functions:
1. Prevent engine oil from spoiling: When the combustible mixture and exhaust gas enter the crankcase, mixing with the engine oil may cause crankcase ventilation hose to deteriorate and affect its lubrication effect. Ventilation crankcase ventilation hose can prevent this from happening.
2. Prevent leakage: Crankcase ventilation breather hose helps maintain the pressure balance of the crankcase, by eliminating excess gas and heat, thereby preventing oil from leaking from the crankshaft oil seal, crankcase liner and other parts.
3. Crankcase ventilation breather hose can prevent oil vapor from polluting the atmosphere: the ventilation system can discharge the gases that enter the crankcase, reduce the impact of these harmful gases on the environment, and reduce the engine's pollution to the atmosphere.
4. Other functions of crankcase ventilation breather hose: Ventilation through crankcase ventilation hose also helps prevent excessive crankcase pressure, extend the service life of engine oil, reduce parts wear and corrosion, and prevent engine oil leakage.

The advantages of our production of ventilation tubing:
In the manufacturing process of ventilation tubing, we use fluorine rubber (FKM) or high-performance silicone materials, which can withstand temperatures in the temperature range of -40℃ to 200℃. Our ventilation tubing is significantly better than ordinary rubber tubing. Crankcase ventilation hose is easy to soften and crack, and crankcase ventilation tube is resistant to oil, fuel and acid channeling gas corrosion, which can make this ventilation tubing long-term use without deformation or deterioration, effectively prolong product life and reduce maintenance requirements. The design has a low permeability structure, which effectively reduces oil vapor emissions, helps the car meet the national six emission standards, and prevents air leakage and gas leakage through strict sealing technology. This crankcase ventilation hose avoids engine jitter or performance degradation. In addition, our ventilation tube fully complies with the EU REACH/ROHS standard, and there is no plasticizer volatilization to protect the air quality in the car. In addition, this ventilation tube also combines a low-permeability design to reduce environmental pollution. Our ventilation tube supports sustainable development and responds to global environmental regulations. Requirements. We adhere to the special mold-opening manufacturing of special cars to ensure a perfect match with the original plug position, and there is no need to heat and soften during installation. This is due to the elastic memory material to achieve fast and easy operation, simplify the maintenance process, reduce the risk of installation errors, and improve user friendliness.
About us:
Our ventilation tubing design focuses on low permeability and efficient sealing, which effectively reduces engine oil vapor emissions. Through the innovation and optimization of crankcase breather hose, this ventilation tubing can help vehicles meet national six emission standards.At the same time, our ventilation tubing has a strict sealing process. Crankcase ventilation tube ensures that air leakage is eliminated and the smooth operation of the engine is guaranteed. Crankcase ventilation tube effectively avoids the performance degradation caused by gas leakage. Our crankcase ventilation tube adheres to the concept of special mold-opening manufacturing for special vehicles, ensuring that each ventilation tubing can be perfectly matched with the original plug. The precise design of the ventilation tubing makes the installation process simple and fast, without additional heating treatment, and the convenient installation characteristics of the crankcase ventilation tube. This not only simplifies the maintenance process, reduces the risk of installation errors, but also improves user satisfaction with crankcase ventilation tube.
