What Does 47.63x70.6x13.5 Mean?

The designation 47.63x70.6x13.5 mm defines the three principal dimensions of the seal:

47.63 mm - inside diameter
70.6 mm - outside diameter
13.5 mm - seal height

These are precise dimensions and should not be unnecessarily rounded when identifying a replacement.

The correct dimensional identification is:

47.63x70.6x13.5 mm

For automotive replacement, the OE reference Toyota 9031147029 provides an additional and highly valuable identification parameter.

TB3 - Corteco Seal Design

The design designation for Corteco 19015056 is:

TB3

The TB3 code is part of the technical identification of this specific Corteco seal.

A generic seal with similar dimensions should therefore not automatically be considered equivalent.

The complete technical specification should include:

47.63x70.6x13.5 mm + NBR + TB3

Toyota 9031147029 OE Reference

One of the strongest identification parameters for Corteco 19015056B is the Toyota original equipment number:

TOYOTA 9031147029

This OE number allows the seal to be identified independently of dimensional measurements.

When an original parts catalogue or removed component specifies 9031147029, Corteco 19015056 / 19015056B can be used as a corresponding aftermarket reference.

Compatibility should still be verified for the specific vehicle version and installation position.

Corteco 19015056 for Toyota Land Cruiser

Parts catalogues list Corteco 19015056B for selected Toyota Land Cruiser applications.

These include selected versions of:

Toyota Land Cruiser J4 / J5
Toyota Land Cruiser Pick-up J4

Application data include certain 3.9 and 4.2 engine versions.

Vehicle model alone should not be used as the only selection criterion.

The preferred identification method is to verify the original Toyota number:

9031147029

together with the Corteco reference and seal dimensions.

NBR Nitrile Rubber

Corteco 19015056B is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is widely used in automotive and industrial sealing applications because of its compatibility with many common mineral oils, greases and lubricants.

Actual suitability depends on the specific lubricant, additives, temperature and operating conditions.

The material specification should therefore be considered together with the seal dimensions and TB3 design.

Why the Exact 47.63 mm Diameter Matters

The inside diameter of this Corteco seal is precisely:

47.63 mm

The outside diameter is:

70.6 mm

and the height is:

13.5 mm

These values should be retained when searching for the correct replacement.

A nominal seal with dimensions such as 48x71x14 mm should not automatically be considered interchangeable simply because its dimensions are close.

For this product, exact dimensional identification is particularly useful:

47.63x70.6x13.5 mm

Corteco 19015056 vs Generic Oil Seal

Several oil seals may have dimensions close to those of Corteco 19015056B.

However, dimensional similarity does not prove interchangeability.

This product is identified by the combination:

Manufacturer: Corteco
Reference: 19015056 / 19015056B
Dimensions: 47.63x70.6x13.5 mm
Material: NBR
Design: TB3
OE reference: Toyota 9031147029

For a vehicle application, the OE reference provides particularly strong confirmation of the required part.

19015056 vs 19015056B

The seal may be found under the references:

Corteco 19015056

and:

Corteco 19015056B

Both forms are useful when searching parts catalogues and cross-reference databases.

The technical identification remains:

NBR + TB3 + 47.63x70.6x13.5 mm

with the Toyota OE reference:

9031147029

How to Select Corteco 19015056

Inside diameter: 47.63 mm
Outside diameter: 70.6 mm
Height: 13.5 mm
Material: NBR
Design: TB3
Toyota OE: 9031147029

The strongest identification is:

Do not select a replacement solely because another seal has approximately the same dimensions.
