The principal dimensions are:
57x71x7 mm
shaft diameter: 57 mm
housing bore diameter: 71 mm
seal width: 7 mm
When selecting an equivalent seal, the dimensions alone are not sufficient. The ACM material, BASLDRWX7 design and application requirements should also be verified.
CORTECO 12015557 is manufactured from ACM, an acrylic rubber commonly used for sealing applications in automotive drivetrains, transmissions and related assemblies.
The ACM material is part of the specified construction of this CORTECO seal and should be considered when selecting a replacement.
A seal with the same 57x71x7 mm dimensions but a different elastomer should not automatically be considered equivalent.
The CORTECO catalogue identifies the seal design as:
BASLDRWX7
This profile incorporates the specific sealing geometry required for the intended application, including an additional dust lip.
For replacement purposes, the complete profile and material should be considered together with the dimensions.
CORTECO catalogues associate reference 12015557 with Volkswagen applications, while product catalogue data identifies the sealing position as a VAG differential shaft.
The seal is also listed in aftermarket catalogues for selected Audi, SEAT and Volkswagen drivetrain and differential applications.
Exact vehicle compatibility should always be confirmed using the OE reference, transmission version and VIN.
CORTECO 12015557 / 12015557B is cross-referenced with OE numbers including:
AUDI 084409189C
SEAT 084409189C
VW 084409189C
VW 084409189A
VW 02D525597
OE numbers provide an important additional identification method when selecting the seal for a specific vehicle or drivetrain assembly.

Dimensions 57x71x7 mm.
ACM material.
BASLDRWX7 design.
Sealing lip construction.
Additional dust lip.
OE reference.
Installation position.
Transmission or differential version.
Another 57x71x7 mm oil seal is not automatically a direct replacement for CORTECO 12015557.
Material, profile and application requirements must also match.
Before installation:
clean the shaft and housing bore
inspect the shaft sealing surface
remove contamination and burrs
check the housing seat
protect the sealing lip from sharp edges
use an appropriate seal installation tool
press the seal evenly into the housing
avoid deformation of the seal body
install the seal in the correct orientation
The sealing lip must not be damaged during assembly.
