CORTECO 20031228 42x64/62x21.2 FPM RWDR-KOMBI BF Rotary Shaft Seal – Renault 7703087160

CORTECO 20031228 / 20031228B is an FPM rotary shaft seal with RWDR-KOMBI / BF construction and dimensions of 42x64/62x21.2 mm. The seal is cross-referenced with Renault OE 7703087160. Current catalogue data for 20031228B also identify CORTECO trade number 82031228 and EAN 3358960187420.

This is not a conventional rotary shaft seal that should be selected using only three basic dimensions. Its 64/62 mm stepped outside geometry, RWDR-KOMBI/BF design and FPM material are important identification characteristics.

CORTECO 20031228 / 20031228B – characteristics

The key product identification data are:

• Manufacturer: CORTECO
• Part number: 20031228 / 20031228B
• CORTECO trade number: 82031228
• Product type: Rotary shaft seal / oil seal
• Seal design: RWDR-KOMBI / BF
• Material: FPM
• International material designation: FKM
• Inside diameter: 42 mm
• First outside diameter: 64 mm
• Second outside diameter: 62 mm
• Width: 21.2 mm
• Complete dimensions: 42x64/62x21.2 mm
• OE brand: Renault
• OE number: 7703087160
• EAN: 3358960187420

The most precise identification is therefore:

CORTECO 20031228 / 20031228B – 42x64/62x21.2 mm – FPM – RWDR-KOMBI BF – Renault 7703087160

CORTECO 20031228 dimensions

The seal has a characteristic geometry with two outside diameters:

The complete dimensional notation should be retained as:

42x64/62x21.2 mm

rather than simplified to 42x64x21.2 mm.

The additional 62 mm dimension forms part of the product geometry and can be important when identifying the correct replacement.

RWDR-KOMBI seal construction

CORTECO catalogue data identify the 20031228 reference as:

RWDR-KOMBI

while current data for 20031228B also use:

BF

This construction should not be treated as a simple standard radial oil seal selected solely by shaft diameter, housing diameter and width.

When selecting an alternative, the complete seal geometry and construction must correspond to the requirements of the assembly.

The key identification combination is:

42x64/62x21.2 + RWDR-KOMBI/BF + FPM

FPM / FKM fluoroelastomer

CORTECO 20031228 is specified in FPM, a fluoroelastomer material.

In international technical terminology, FKM is also widely used for this elastomer family. For international searches, customers may therefore encounter either FPM or FKM in connection with this seal.

Material is an important selection parameter.

An NBR, ACM or other elastomer seal should not automatically be considered equivalent simply because its basic dimensions are similar.

For CORTECO 20031228, the material should be considered together with:

RWDR-KOMBI/BF construction
42x64/62x21.2 mm dimensions
Renault OE 7703087160

CORTECO 20031228 – Renault 7703087160

The confirmed Renault OE cross-reference for this product is:

RENAULT 7703087160

This is one of the strongest identifiers for customers searching for the seal without knowing the CORTECO reference.

The same product may therefore be searched using:

CORTECO 20031228

CORTECO 20031228B

CORTECO 82031228

or:

RENAULT 7703087160

When selecting the part for a specific application, the OE number should be checked against the documentation for the relevant vehicle or assembly.

Renault 7703087160 – which oil seal?

The Renault OE number 7703087160 is cross-referenced with CORTECO 20031228 / 20031228B, an FPM rotary shaft seal with dimensions of 42x64/62x21.2 mm.

The principal dimensions and characteristics are:

42 mm – inside diameter
64 mm – first outside diameter
62 mm – second outside diameter
21.2 mm – width
FPM/FKM – fluoroelastomer material
RWDR-KOMBI / BF – seal construction

These parameters allow the Renault OE number to be connected with the exact physical and material specification of the CORTECO seal.

CORTECO 20031228 or 20031228B?

The product can be encountered under two closely related references:

20031228

and:

20031228B

Older CORTECO data use 20031228, while current aftermarket catalogue data commonly index 20031228B together with trade number 82031228, BF designation, EAN 3358960187420 and Renault OE 7703087160.

Including both references on the product page helps customers who may be searching using either catalogue number.

For invoicing, warehouse identification and order processing, the reference shown on the current product packaging should be used.

What is CORTECO 82031228?

Another number associated with this product in current catalogue data is:

82031228

It is listed as a CORTECO trade/reference number connected with 20031228B.

International customers may therefore search for:

CORTECO 82031228

as well as:

CORTECO 20031228
CORTECO 20031228B
Renault 7703087160

Cross-checking these numbers together with the physical dimensions provides more reliable identification than using a single dimension alone.

Why is 42x64/62x21.2 important?

A conventional oil seal is often searched using three dimensions:

shaft diameter x housing diameter x width

CORTECO 20031228 has the more specific dimensional notation:

42x64/62x21.2 mm

with two relevant outside diameters:

64 mm and 62 mm

This distinction is important.

A generic 42x64x21.2 oil seal should therefore not automatically be treated as an equivalent to CORTECO 20031228.

The full 42x64/62x21.2 mm geometry should be verified.

Selecting an equivalent for CORTECO 20031228

When selecting a replacement, compare:

1. CORTECO reference 20031228 / 20031228B
2. CORTECO trade number 82031228
3. Renault OE number 7703087160
4. Inside diameter 42 mm
5. First outside diameter 64 mm
6. Second outside diameter 62 mm
7. Width 21.2 mm
8. Material FPM/FKM
9. Seal design RWDR-KOMBI / BF
10. Installation geometry and application requirements

Matching only the 42 mm and 64 mm diameters does not establish full interchangeability.

The stepped external geometry, material and complete sealing construction must also be compatible.
