Ford OE Reference Numbers

CORTECO 12012570 is associated with the following Ford references:

Ford 6142760
Ford 6149223
Ford 86VB1175A2A
Ford 86VB1175A3A

The first three references are consistently listed in aftermarket catalog data, while 86VB1175A3A also appears as an OE cross-reference for this CORTECO seal.

BASLSFDRWX7 Seal Design

The designation BASLSFDRWX7 identifies the specific construction of this CORTECO shaft seal. It is not simply a conventional single-lip oil seal.

The product incorporates an additional dust protection lip, helping isolate the primary sealing area from road dust, dirt and other external contaminants. Catalog data also specifies an alternating twist configuration.

These construction details are important when selecting a replacement because another seal with similar nominal diameters may not provide the same geometry or operating characteristics.

NBR Sealing Material

The sealing element is manufactured from NBR, nitrile butadiene rubber.

NBR is widely used for automotive radial shaft seals because it provides good resistance to:

• mineral oils
• lubricating greases
• many oil-based operating fluids
• mechanical wear under correctly specified operating conditions

The suitability of NBR for a particular application depends on operating temperature, lubricant type, shaft speed and environmental conditions.

Dimensions 54.51x76.09x9.5/15.47 mm

The principal dimensions are:

Inner diameter: 54.51 mm
Outer diameter: 76.09 mm
Height 1: 9.5 mm
Height 2: 15.47 mm

These exact dimensions are confirmed in product catalogue data for CORTECO 12012570B.

The two height values are particularly important. This is a specific profiled seal construction and should not be treated as a conventional 54.5x76x9.5 mm radial shaft seal.

Wheel Hub Sealing Application

CORTECO 12012570B is catalogued as a shaft seal for the wheel hub.

In this type of application, the seal helps retain lubricant within the mechanical assembly while reducing the ingress of contaminants into the working area.

The additional dust lip is particularly useful in automotive wheel and axle environments where the sealing position may be exposed to dirt and road contamination.

Ford Vehicle Applications

Catalogue data associates this seal with selected Ford vehicles, including applications within the Ford Transit, Sierra and P100 families.

Compatibility should nevertheless be confirmed against the exact:

Ford OE number
vehicle model
production year
engine or drivetrain version
installation position

Vehicle make alone is not sufficient for reliable replacement identification.

Why the Exact Dimensions Matter

The dimensions 54.51 mm and 76.09 mm originate from a specific application geometry and should not simply be rounded to a standard metric size.

For this reason, a conventional seal with approximately 55 mm inner diameter and 76 mm outer diameter should not automatically be considered interchangeable.

Correct identification should be based on:

CORTECO number: 12012570 / 12012570B
Design: BASLSFDRWX7
Dimensions: 54.51x76.09x9.5/15.47 mm
Material: NBR
Ford OE reference: corresponding original part number

Replacement Selection

Before replacing CORTECO 12012570, verify:

Brand: CORTECO
Part number: 12012570 / 12012570B
Material: NBR
Design: BASLSFDRWX7
Inner diameter: 54.51 mm
Outer diameter: 76.09 mm
Heights: 9.5 / 15.47 mm
Dust lip: Yes
Vehicle application: Ford

CORTECO's official online catalogue allows parts to be searched by vehicle, engine or direct article reference, which is useful for final vehicle-specific verification.

Operational Advantages

Application-specific geometry: 54.51x76.09x9.5/15.47 mm dimensions correspond to a dedicated automotive sealing arrangement.

Dust protection: the additional lip helps protect the primary sealing zone against external contamination.

NBR elastomer: suitable for many applications involving mineral oils and lubricating greases.

Alternating twist design: catalogue data identifies the seal with an alternating twist configuration.

OE identification: Ford reference numbers simplify replacement verification.

Wheel hub application: designed for a demanding automotive sealing position exposed to lubricant and external contamination.
