What Does 45x63x7 Mean?

The designation 45x63x7 mm defines the three principal installation dimensions:

45 mm - inside diameter
63 mm - outside diameter
7 mm - seal width

All three dimensions must correspond to the installation.

Dimensions alone, however, are not sufficient for complete identification. The TB2 design, NBR material and Corteco reference 19016479 should also be verified.

TB2 - Corteco Seal Design

Corteco identifies this particular seal with the design code:

TB2

The design designation is an important part of the product specification.

A generic 45x63x7 mm oil seal should therefore not automatically be considered equivalent to Corteco 19016479 simply because the dimensions are identical.

For precise identification use:

19016479 / 19016479B + TB2 + NBR + 45x63x7 mm

NBR Nitrile Rubber

Corteco 19016479 is manufactured from NBR - Nitrile Butadiene Rubber.

NBR is one of the most widely used elastomers in oil seals and other technical sealing components due to its compatibility with many common:

mineral oils,
lubricating greases,
industrial lubricants.

Actual compatibility should always be checked against the specific medium, additives, temperature and operating conditions.

Daihatsu 9004311111

One of the key OE cross references for Corteco 19016479 is:

DAIHATSU 9004311111

This number provides an important additional method of identifying the required seal.

When an original component or parts catalogue specifies 9004311111, the Corteco reference can be searched as:

Corteco 19016479 / 19016479B

Vehicle compatibility should still be verified for the specific model and installation position.

Daihatsu 9004311150

The second important Daihatsu OE cross reference is:

DAIHATSU 9004311150

Both OE numbers are associated with the Corteco 45x63x7 NBR TB2 seal:

9004311111
9004311150

Including these numbers in product identification significantly reduces the risk of selecting a different 45x63x7 seal based only on dimensions.

Corteco 19016479 vs Generic 45x63x7 Oil Seal

Several seals can share the same basic 45x63x7 mm dimensions.

They may nevertheless differ in:

seal design,
elastomer material,
lip geometry,
intended installation.

For this product the relevant specification is:

Manufacturer: Corteco
Reference: 19016479 / 19016479B
Dimensions: 45x63x7 mm
Material: NBR
Design: TB2

Therefore, dimensions alone should not be treated as proof of full interchangeability.

Why the Corteco Reference Matters

The number 19016479 identifies a specific Corteco sealing product rather than only a dimensional size.

This makes it possible to distinguish it from other seals measuring 45x63x7 mm.

When replacing the original component, the strongest identification is obtained by combining:

Corteco reference + dimensions + material + design + OE number

For this seal:

19016479 + 45x63x7 + NBR + TB2 + Daihatsu OE

How to Select Corteco 19016479

Before selecting a replacement, verify:

Manufacturer: Corteco
Product reference: 19016479 / 19016479B
Inside diameter: 45 mm
Outside diameter: 63 mm
Width: 7 mm
Material: NBR
Design: TB2

For Daihatsu applications, also verify the original OE number:

9004311111

or

9004311150

Matching the OE reference together with the Corteco number and technical specification provides much stronger identification than dimensions alone.
