Elring 705.225 Engine Oil Pump Seal

Elring 705.225 Engine Oil Pump Seal

Elring 705.225 is an engine oil pump seal built as a precision O-ring for sealing critical oil pump interfaces. With a 20 mm inner diameter, 25 mm outer diameter, and 2.5 mm thickness, it provides the dimensional accuracy needed for BMW and Mini applications that rely on a tight, stable seal.

Key Features

• Engine oil pump seal in O-ring shape
• Inner diameter: 20 mm
• Outer diameter: 25 mm
• Thickness: 2.5 mm
• Made from FPM (fluoride rubber) for oil-resistant sealing performance
• Elring part number 705.225

Detailed Description

This Elring oil pump seal is specified for a range of BMW and Mini vehicles, including BMW 325i, BMW 330i, BMW X5, BMW M3, and Mini Cooper applications. The FPM material is selected for use in engine environments where exposure to oil and heat is routine, while the O-ring profile supports a consistent seal at the oil pump interface. Elring 705.225 is also a direct reference point for service work where exact dimensions matter, especially on BMW engines that require a 20 x 25 x 2.5 mm seal.

This part cross-references 09D 321 379 and 11 12 7 806 691 for the same application.

Common Repair Uses

• Oil seepage at the oil pump sealing surface
• Loss of seal integrity from heat-aged rubber

• Leak correction on BMW and Mini engines using a 20 mm x 25 mm O-ring seal
• Restoring a proper seal where the original FPM ring has hardened or flattened

Installation Notes and Tips

Verify the seal dimensions against the removed part before installation. Clean the sealing groove and mating surfaces thoroughly, and inspect for scoring, debris, or distortion that could affect the seal. Use care during installation to avoid twisting or nicking the O-ring, and confirm the oil pump assembly is seated evenly before reassembly.
