Elring 012.380 Engine Crankshaft Seal - Rear

Elring 012.380 Crankshaft Seal

Elring 012.380 is an engine crankshaft seal built for transmission-end sealing on select Audi and Volkswagen applications. It uses PTFE and ACM materials, an 85.0 mm inside diameter, and a housing-style design with a mounting sleeve for accurate installation.

Key Features

• PTFE (polytetrafluoroethylene) and ACM (polyacrylate rubber) sealing materials
• 85.0 mm inside diameter for the specified crankshaft application
• Housing type design for controlled seal placement
• Radial shaft seal design: IWD
• Includes mounting sleeve for installation support
• Swirl type: LD

Detailed Description

This Elring crankshaft seal is specified for transmission-end sealing where crankshaft oil control is critical. The PTFE sealing lip and ACM support material are selected for engine sealing performance, while the housing-style construction helps maintain proper alignment at the crankshaft opening. Elring 012.380 is a direct-fit sealing component for select Audi A3, Audi A4, and Volkswagen Jetta applications, including 2004-2007 Audi A3, 2006-2008 Audi A3 rear, 2005-2008 Audi A4, 2006-2009 Volkswagen Jetta, and 2010 Volkswagen Jetta rear/transmission end configurations.

This part cross-references Four Seasons (e.g., 36783, 77318) for the same application.

What It Helps Address

• Engine oil leakage at the crankshaft seal area
• Oil seepage at the transmission-end crankshaft opening
• Seal wear from age, heat, and crankshaft rotation
• Improper sealing after service on Audi A3, Audi A4, or Volkswagen Jetta engines
• Noise or contamination concerns caused by a compromised rear main seal area

Installation Notes and Tips

Verify the 85 mm inside diameter, housing style, and left-hand twist/swirl specification before installation. Use the included mounting sleeve to protect the sealing lip during placement, and confirm the seal is seated squarely at the transmission end. For 2010 Volkswagen Jetta and rear-position Audi A3 applications, match the fitment notes exactly to the vehicle configuration.

Quality Assurance

Elring is a recognized sealing-system manufacturer, and this crankshaft seal is built to OE-style dimensional and material specifications for the listed Audi and Volkswagen applications. Confirm fitment by year, model, position, and notes before installation.
