Introduction of valve stem seal kit：
Valve stem seal kit is the core sealing assembly of the engine. It is vulcanized from the outer skeleton and fluorine rubber, and is equipped with a self-tightening spring. Our Sortech valve stem seal kit is specially used for sealing valve guide rods, which can effectively prevent oil from entering the intake and exhaust pipes and combustion chambers. Our valve stem seal kit can also avoid leakage of mixed gases and exhaust gases and ensure engine efficiency. As an important part of the valve set, our valve stem seal kit works in a high-temperature oil environment, so it uses heat-resistant and oil-resistant fluorine rubber materials. In this way, our valve stem seal kit guarantees the long-term reliable operation of the engine.

Advantages of valve oil seal for Mercedes Benz：
As a professional valve oil seal for Mercedes Benz manufacturer, Sortech focuses on the development of high-performance valve oil seal for Mercedes Benz to provide excellent sealing solutions for engines. Our valve oil seal for Mercedes Benz guarantees the strong sealing and durability of valve oil seal for Mercedes Benz through innovative design and cutting-edge materials. Our valve oil seal for Mercedes Benz adopts a triple lip design (main sealing lip + dust-proof lip + spring compensation), which is 60% more sealing than traditional single-lip oil seals, effectively preventing oil leakage. The dynamic pressure adaptive technology enables engine valve oil seal to maintain zero leakage under the condition of axis micro-yaw ≤0.5mm, greatly improving the reliability of engine valve oil seal. In addition, our engine valve oil seal uses advanced wear-resistant materials such as hydrogenated nitrile rubber (HNBR), fluorine rubber (FKM) or polyacrylate rubber (ACM) to increase the wear-resistant life by more than 50%. Our engine valve oil seal is equipped with teflon coating, which reduces the coefficient of friction by 70% and the shaft wear rate by 90%. Combined with strong corrosion resistance, it resists oil additives, acidic substances and external mud erosion, which doubles the life of our engine valve oil seal in different environments. Our engine valve oil seal design not only improves engine efficiency, but also reduces the frequency of maintenance.
Service advantage：

We provide remote installation guidance for engine valve stem oil seal, including graphic and video tutorials, to help customers accurately operate valve oil seal with different engine models.In terms of fault diagnosis, we support engineers to analyze abnormal problems of valve oil seal online, such as wear or oil leakage, so that valve oil seal can be repaired in time. At the same time, we support material selection consultation to recommend the best valve oil seal solution according to your working conditions, such as the selection of heat-resistant and oil-resistant materials to prevent failures such as burning oil. These services ensure the correct application of your valve oil seal and extend engine life.
Engine valve oil seal maintenance and replacement guide:
As a wear-and-tear part, engine valve oil seal rubber will inevitably age or wear out after long-term use, and it is essential to replace engine valve oil seal in time. The replacement of valve oil seal is not a simple maintenance project, it involves professional disassembly and installation, and the material cost plus working hours totals about a few thousand yuan. In order to ensure the safety and performance of valve oil seal, the replacement of valve stem seal kit must be operated by a regular repair shop to avoid improper maintenance causing more engine failures. At the same time, we recommend regularly checking the status of engine valve stem oil seal to ensure that engine valve stem oil seal is working normally to effectively prevent oil burning problems and extend the overall engine life.
