Introduction to Crankshaft Seals
The crankshaft seal is a critical component in a vehicle's engine, ensuring the smooth operation of the crankshaft and preventing oil leaks. For Audi vehicles, the crankshaft seal (part number 038103171) is designed with precision to meet the demands of high-performance engines. This article explores the features, advantages, technical specifications, and applications of this essential automotive part, as well as the company behind its production.
Product Overview
The crankshaft seal 038103171 is specifically engineered for Audi vehicles, offering a robust solution to engine oil leakage. This seal features a left-hand twist swirl type design, which ensures a secure fit and optimal performance. Manufactured from high-quality PTFE (polytetrafluoroethylene) and ACM (polyacrylate rubber) materials, the seal is built to withstand extreme temperatures and pressures, making it ideal for demanding driving conditions. The seal includes a housing and mounting sleeve for easy installation, reducing the need for specialized tools and saving time during maintenance.

Key Features and Advantages
1. Durable Materials
The crankshaft seal is crafted from PTFE and ACM, materials renowned for their resistance to heat, chemicals, and wear. PTFE is a synthetic fluoropolymer known for its low friction and non-stick properties, while ACM offers excellent resistance to oil and heat. Together, these materials ensure the seal maintains its integrity over time, even under harsh engine conditions.
2. Left-Hand Twist Swirl Design
The left-hand twist swirl type design is specifically tailored for Audi vehicles, providing a tight seal that minimizes the risk of oil leakage. This design also enhances the seal's ability to handle rotational forces, ensuring consistent performance during engine operation.
3. Easy Installation
With a housing and mounting sleeve included, the installation process is streamlined. The seal is designed to be mounted dry without the need for additional oil or grease, which simplifies the procedure and reduces the risk of contamination.
4. OEM Compatibility
As an OEM (Original Equipment Manufacturer) part, the crankshaft seal 038103171 is designed to match the specifications of Audi's original components. This ensures a perfect fit and performance, maintaining the vehicle's factory standards.
