CORTECO 12019647 56x72x8 FPM B1BAVISLRDX7 Transmission Rotary Shaft Seal

CORTECO 12019647 56x72x8 FPM B1BAVISLRDX7 Transmission Rotary Shaft Seal

CORTECO 12019647, also listed as 12019647B, is an FPM rotary shaft seal / oil seal catalogued for transmission shaft applications. Its exact dimensions are 56x72x8 mm, comprising a 56 mm inside diameter, 72 mm outside diameter and 8 mm width.

The CORTECO dimensional catalogue identifies this reference as B1BAVISLRDX7. The seal also features a right-hand dynamic twist and an additional dust lip.

The key product identification relationship is:

CORTECO 12019647 → 12019647B → 82019647 → FPM/FKM → B1BAVISLRDX7 → 56x72x8 mm → right-hand twist → dust lip → transmission shaft seal → Mercedes-Benz

For precise identification, the complete combination 56x72x8 mm + FPM/FKM + B1BAVISLRDX7 + right-hand twist + dust lip should be considered rather than the dimensions alone.

CORTECO 12019647 dimensions

The nominal seal size is therefore:

56x72x8 mm

However, the dimensions alone are not sufficient to confirm technical interchangeability.

A different 56x72x8 rotary shaft seal may use another elastomer, lip geometry or dynamic sealing structure.

FPM / FKM fluorocarbon rubber

The specified elastomer for CORTECO 12019647 is:

FPM – fluorocarbon rubber

In international technical terminology, FKM is also widely used for this elastomer family.

Both terms are therefore useful for product identification and search:

CORTECO 12019647 FPM
CORTECO 12019647 FKM
FPM oil seal 56x72x8
FKM rotary shaft seal 56x72x8

Material must be considered when selecting an alternative. An NBR, ACM or VMQ seal with the same dimensions should not automatically be regarded as a direct replacement.

B1BAVISLRDX7 – CORTECO design

The CORTECO dimensional catalogue identifies reference:

12019647

as:

FPM B1BAVISLRDX7 56x72x8

This is important because the product may sometimes be described online with shortened or incorrectly transcribed design codes.

For technically precise product identification, use:

CORTECO 12019647 FPM B1BAVISLRDX7 56x72x8

The exact manufacturer part number should remain the primary identifier.

Right-hand dynamic twist

CORTECO 12019647B is specified with a:

right-hand dynamic twist

This feature is also described in technical catalogue terminology as Right-hand Twist.

The dynamic structure is an important functional characteristic of the sealing lip area.

Therefore, two rotary shaft seals with identical 56x72x8 mm dimensions should not automatically be treated as technically equivalent when their dynamic twist structures differ.

Additional dust lip

CORTECO 12019647B also features an:

additional dust lip

The additional lip provides a secondary barrier on the external side of the main dynamic sealing area.

When comparing alternatives, the lip configuration should therefore be considered together with the dimensions, material and dynamic twist.

A basic single-lip 56x72x8 seal is not necessarily identical to this CORTECO reference.

CORTECO 12019647 – transmission shaft seal

CORTECO 12019647B is catalogued as a manual transmission shaft seal.

Depending on the exact gearbox application, customers may search for the same component using terms such as:

transmission shaft seal 56x72x8
gearbox shaft seal 56x72x8
gearbox oil seal 56x72x8
manual transmission oil seal
input shaft seal 56x72x8
CORTECO transmission seal 12019647

The exact installation position should always be confirmed for the specific transmission.

CORTECO 12019647 – Mercedes-Benz applications

CORTECO 12019647 / 12019647B is associated in parts catalogues with Mercedes-Benz transmission applications.

OE references listed for this seal include:

0199970347
0199970447
0199970547
0199970647
0209971747
0229970647
0239970647
0239977847
A0199970547

Because OE listings can vary by gearbox and vehicle configuration, exact compatibility should be verified against the OE number and transmission data before installation.

Mercedes-Benz 0199970547 – which oil seal?

The Mercedes-Benz OE reference:

0199970547

is associated in aftermarket catalogues with:

CORTECO 12019647B

The main identification parameters are:

56x72x8 mm
FPM/FKM
B1BAVISLRDX7
right-hand dynamic twist
additional dust lip

This relationship makes the product relevant for searches such as:

0199970547 oil seal
0199970547 shaft seal
Mercedes 0199970547 seal
A0199970547 oil seal
0199970547 CORTECO

Exact fitment should be confirmed from the Mercedes-Benz OE reference and transmission type.

Mercedes-Benz Actros, Atego, Axor and Econic

Aftermarket application catalogues associate this seal with selected versions of Mercedes-Benz commercial vehicles, including:

Actros
Actros MP2 / MP3
Atego
Axor
Axor 2
Econic

This does not mean that CORTECO 12019647 fits every version of these vehicle families.

Correct selection should be based on:

OE number + transmission type + vehicle configuration

and, where necessary, VIN-specific parts data.

CORTECO 82019647 – what is this number?

The CORTECO trade number associated with 12019647B is:

82019647

The product may therefore appear in databases under:

CORTECO 12019647
CORTECO 12019647B
CORTECO 82019647

Including these references on the same product page helps workshops, international B2B buyers, distributors and maintenance departments identify the correct seal when working from different catalogues or ERP systems.

CORTECO 12019647 or 12019647B?

Both reference forms may appear in technical and aftermarket databases:

12019647

and:

12019647B

The basic reference 12019647 remains useful for searches based on older documentation and dimensional catalogues, while 12019647B is widely used in current aftermarket data.

The actual CORTECO reference printed on the supplied product packaging should remain the primary physical stock identifier.

EAN 3358960145222

The EAN associated with CORTECO 12019647B is:

3358960145222

This provides an additional identifier for:

international distributors,
B2B purchasing departments,
workshops,
warehouse systems,
ERP databases and parts catalogues.

Customers may therefore also search for:

3358960145222 CORTECO
CORTECO EAN 3358960145222

Why is 56x72x8 not enough to select the seal?

A rotary shaft seal is defined by more than its three basic dimensions.

CORTECO 12019647 is identified by the combination:

56 mm – inside diameter
72 mm – outside diameter
8 mm – width
FPM/FKM – material
B1BAVISLRDX7 – design
right-hand dynamic twist
additional dust lip
OE reference and application

Another oil seal may have exactly the same 56x72x8 mm dimensions but a different construction.

Identical dimensions alone do not guarantee interchangeability.

How to select an alternative to CORTECO 12019647

When comparing another seal with CORTECO 12019647 / 12019647B, verify:

1. CORTECO reference 12019647 / 12019647B
2. trade number 82019647
3. inside diameter 56 mm
4. outside diameter 72 mm
5. width 8 mm
6. material FPM/FKM
7. design B1BAVISLRDX7
8. right-hand dynamic twist
9. additional dust lip
10. OE reference
11. exact gearbox and installation position

A dimensional match alone is not sufficient to confirm technical interchangeability.
