12012560 CORTECO 53x68x10 FPM B1BASLRDX7 Crankshaft Oil Seal

12012560 CORTECO - Product Characteristics

CORTECO 12012560, currently catalogued as 12012560B, is an FPM crankshaft radial shaft seal with dimensions 53x68x10 mm. The seal is specified for the transmission side of the crankshaft and has a right-hand twist sealing structure and a dust lip. The confirmed CORTECO trade designation is B1BASLRDX7 Simmerring, with additional trade number 82012560.

The exact reference is associated with FIAT OE numbers 40004880, 7622909 and 7623869. These OE numbers, together with the dimensions, material, installation position and directional sealing design, provide important criteria for identifying the correct crankshaft seal.

Dimensions

Verified dimensions for CORTECO 12012560 / 12012560B:

Inside Diameter: 53 mm
Outside Diameter: 68 mm
Height: 10 mm
Dimensions: 53x68x10 mm
Material: FPM - fluoro rubber
Profile / Trade Number: B1BASLRDX7 Simmerring
Additional Trade Number: 82012560
EAN: 3358960125606
Fitting Position: Transmission side
Twist: Right-hand Twist
Dust Protection: With dust lip

The 53 mm inside diameter corresponds to the shaft sealing diameter, while the 68 mm outside diameter corresponds to the housing bore interface. The axial height is 10 mm.

FPM Material

CORTECO 12012560B is manufactured from FPM (fluoro rubber). This material designation is directly confirmed for the exact reference.

FPM is therefore an important part of the technical identity of this seal and should be considered when comparing it with another 53x68x10 mm radial shaft seal.

A specific temperature range or chemical compatibility limit should not be assigned to this exact product solely from generic FPM properties without corresponding CORTECO documentation.

B1BASLRDX7 Profile

The confirmed trade designation for this reference is:

B1BASLRDX7 Simmerring

This profile is part of the exact product specification and should be retained when identifying or comparing CORTECO 12012560 / 12012560B.

Importantly, some commercial sources also list B1BAVISLRDX7 as an alternative CORTECO designation. The current TecDoc-derived records consistently identify B1BASLRDX7 Simmerring, so this is the safer primary designation for the product page.

Right-Hand Twist

The exact 12012560B seal is specified with a Right-hand Twist characteristic.

This directional feature is technically relevant for the crankshaft sealing position. A generic 53x68x10 mm oil seal with a different directional structure should therefore not automatically be considered identical.

When selecting a replacement, the directional characteristic should be checked together with dimensions, material and installation position.

Dust Lip

Catalog data explicitly specify with dust lip for CORTECO 12012560B.

The additional dust lip provides a secondary barrier on the external side of the primary sealing system, helping limit contamination reaching the main sealing area.

Unlike an interpretation based solely on the B1BASLRDX7 code, the presence of the dust lip is directly confirmed in the product data for this exact reference.

Crankshaft Application

CORTECO 12012560B is catalogued specifically as a crankshaft shaft seal, with the fitting position identified as transmission side.

This means the technically appropriate English product terms include:

crankshaft oil seal
crankshaft radial shaft seal
rear crankshaft seal
transmission-side crankshaft seal

The fitting position is important because crankshaft seals can differ between the transmission side and the opposite end even when some dimensions appear similar.

FIAT OE References

The following FIAT OE numbers are confirmed for CORTECO 12012560 / 12012560B:

FIAT: 40004880
FIAT: 7622909
FIAT: 7623869

These OE references provide a stronger identification criterion than dimensions alone.

Catalog data also associate the seal with specific FIAT Cinquecento 0.7 configurations, including engine codes 170 A.000 and 170 A.046. Exact vehicle compatibility should still be checked using the OE number, engine and vehicle data before installation.

Selection and Interchangeability

A generic 53x68x10 mm FPM oil seal should not automatically be considered technically equivalent to CORTECO 12012560B.

For replacement selection, compare:

• CORTECO reference 12012560 / 12012560B
• 53 mm inside diameter
• 68 mm outside diameter
• 10 mm height
• FPM material
• B1BASLRDX7 profile
• right-hand twist
• dust lip
• transmission-side fitting position
• FIAT OE reference
• exact crankshaft application

The dimensions alone do not define the complete sealing configuration.
