Corteco 12031235B AUV5 482 - Characteristics

The key identifiers of this exact sealing ring are:

Part number: 12031235B
Design: AUV5 482
Material: PU - Polyurethane
Dimensions: 43x55x8.6 mm
DANA OE: 000051684

These parameters should be considered together when identifying the product or selecting an alternative.

The dimensions alone do not fully define the construction or material of the seal.

Corteco 12031235B Dimensions

Verified catalog dimensions:

Inside diameter: 43 mm
Outside diameter: 55 mm
Height: 8.6 mm
Dimensions: 43x55x8.6 mm

For this particular reference, height is retained as the dimensional description because this is how the parameter is represented in the available exact-reference catalog data.

It should not automatically be assigned a different dimensional symbol used for conventional radial shaft oil seal designs.

PU - Polyurethane

Corteco dimensional data identify the material of 12031235B as:

PU - Polyurethane

Another Corteco catalog uses the material designation:

AU

for this exact reference.

This is an important distinction because 12031235B should not be described as a standard NBR or FPM oil seal.

The material specification forms part of the exact product identification and should be retained when selecting a replacement.

AUV5 482 Design

The manufacturer design designation is:

AUV5 482

This designation is directly associated with Corteco 12031235B 43x55x8.6 mm.

The design code should be retained in technical documentation, product titles and replacement searches because the basic dimensions alone do not define the construction of this sealing ring.

The individual characters within AUV5 482 should not be assigned specific technical meanings without an explicit Corteco definition for this design.

DANA OE 000051684

Catalog cross-reference data associate Corteco 12031235B with:

DANA 000051684

This OE number is an important additional identifier when the original component is being selected by part number.

The DANA cross-reference should not, however, be interpreted as confirmation of compatibility with every axle, transmission or machine using DANA components.

The required OE number should be verified for the specific assembly.

Product Identification Numbers

The following identifiers are associated with this sealing ring:

Corteco part number: 12031235B
Base reference: 12031235
Corteco trade number: 82031235
Design: AUV5 482
DANA OE: 000051684
EAN: 3358960465511

These identifiers provide substantially more precise product identification than searching by the 43x55x8.6 mm dimensions alone.

Why 43x55 mm Is Not Sufficient for Identification

Corteco catalogs contain other seals with the same 43 mm inside diameter and 55 mm outside diameter but different constructions, materials and heights.

Examples include:

19019528B - NBR - KCY - 43x55x8 mm

12031235B - PU - AUV5 482 - 43x55x8.6 mm

19030459B - NBR - TC4 - 43x55x9.5 mm

This demonstrates why even a relatively small difference in the third dimension can identify a completely different Corteco reference.

For this product, the correct identification is:

Corteco 12031235B AUV5 482 PU 43x55x8.6 mm

Replacement and Interchangeability

When selecting a replacement for Corteco 12031235B, compare at least:

Part number: 12031235B
Design: AUV5 482
Material: PU / AU
Inside diameter: 43 mm
Outside diameter: 55 mm
Height: 8.6 mm
DANA OE: 000051684

Identical or similar dimensions do not automatically establish interchangeability.

A standard NBR or FPM 43x55 mm radial shaft seal should therefore not be considered equivalent without technical confirmation of the construction, material and requirements of the specific application.
