MAHLE Engine Crankshaft Seal

The MAHLE engine crankshaft seal (also called a crank seal, crankshaft oil seal or front/rear main seal) keeps engine oil inside the crankcase where the crankshaft exits the engine block. It also keeps dirt and contaminants out. A good seal helps prevent oil leaks and protects the bearings and other internal components.

Key Features:

• Made by MAHLE, a leading OE supplier of engine components and sealing products
• Designed to seal the rotating crankshaft against the engine block or timing cover
• Built with sealing lip materials chosen to resist engine oil, heat and wear
• Engineered for a precise fit and reliable, long-lasting sealing performance
• Suited to routine maintenance, leak repair and engine rebuilds

MAHLE draws on its original equipment experience to build aftermarket sealing parts that meet demanding engine requirements. Choose the specific part number for your application to get the correct seal design and size.
