The crankshaft seal is a critical component in modern vehicle engines, ensuring the efficient operation of the crankshaft while preventing oil leaks. Designed for precision and durability, the crankshaft seal 038103171 stands out as a reliable solution for automotive maintenance. Manufactured by JULU YJM HWMF SEAL CO.,LTD., this product combines advanced materials and engineering to meet the demands of high-performance engines. This article explores its features, advantages, technical specifications, and applications, supported by authoritative insights from the National Institute of Standards and Technology (NIST).

Product Features and Design

The crankshaft seal 038103171 is engineered with a left-hand twist swirl type design, specifically tailored for Audi vehicles. This unique configuration ensures optimal sealing performance under varying engine conditions. The seal is constructed using high-quality materials, including PTFE (polytetrafluoroethylene) and ACM (polyacrylate rubber), which provide exceptional resistance to heat, oil, and wear. These materials are chosen for their ability to maintain integrity under extreme operating conditions, making the seal suitable for both standard and high-performance engines.

One of the standout features of this seal is its housing and mounting sleeve, which simplifies installation and ensures a secure fit. The design eliminates the need for additional oils or greases during installation, as the seal is intended to be mounted dry. This not only reduces maintenance costs but also minimizes the risk of contamination from external lubricants.
