Technical Data - CORTECO 19034392

CORTECO 19034392 - Precise Product Identification

The complete product designation is:

CORTECO 19034392 NBR VB 76.2x89.03x7.92 mm

Catalogue reference:

CORTECO 19034392B

Commercial number:

82034392

Material:

NBR

Profile:

VB

Dimensions:

76.2x89.03x7.92 mm

Confirmed OE reference:

CATERPILLAR 5P0064

For this product, retaining the precise decimal dimensions is particularly important. The specification should not be simplified to 76x89x8 mm.

CORTECO 19034392 Dimensions

Exact catalogue dimensions:

• inner diameter: 76.2 mm
• outer diameter: 89.03 mm
• width: 7.92 mm

Complete dimensions:

76.2x89.03x7.92 mm

These dimensions correspond closely to values derived from the imperial measurement system.

In particular:

• 76.2 mm = exactly 3 inches
• 89.03 mm ≈ 3.505 inches
• 7.92 mm ≈ 0.312 inches

Rounding the dimensions to 76x89x8 mm could therefore result in incorrect seal selection.

NBR - Nitrile Butadiene Rubber

CORTECO 19034392 is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is one of the most widely used elastomers in technical sealing applications.

Typical NBR characteristics include:

• good resistance to many mineral oils,
• good resistance to lubricating greases,
• good mechanical properties,
• good performance in correctly designed sealing systems,
• widespread use in machinery, vehicles and industrial equipment.

Actual operating characteristics depend on the specific NBR compound, operating medium and application conditions.

A specific temperature range should therefore not be assigned to CORTECO 19034392 solely from generic NBR material data.

CORTECO VB Profile

The confirmed CORTECO profile designation is:

VB

The VB profile is an integral part of the technical identification of this product.

The VB designation should not automatically be decoded according to the nomenclature used by another seal manufacturer.

For technical purchasing and replacement selection, retain the complete designation:

CORTECO 19034392 NBR VB 76.2x89.03x7.92 mm

CORTECO 19034392 and CATERPILLAR 5P0064

The confirmed OE reference is:

CATERPILLAR 5P0064

This is an important identifier for machinery service companies, maintenance departments, technical purchasing teams and spare-parts distributors.

The product may therefore be searched as:

CATERPILLAR 5P0064 seal

CAT 5P0064 seal

5P0064 oil seal

5P0064 shaft seal

as well as by its CORTECO references:

CORTECO 19034392

CORTECO 19034392B

For installation in a specific machine, the OE reference should also be confirmed against the parts documentation for the particular CATERPILLAR model.

Why Are the Exact Dimensions Important?

For CORTECO 19034392, the difference between:

76.2x89.03x7.92 mm

and the simplified:

76x89x8 mm

should not be ignored.

In technical sealing systems, even relatively small dimensional differences can affect:

• shaft fit,
• housing fit,
• seal stability,
• installation,
• sealing performance.

The exact catalogue dimensions should therefore be used when ordering or cross-referencing this product.

Is 76.2x89.03x7.92 an Imperial-Based Size?

The dimensions indicate a construction based on values characteristic of the imperial measurement system.

In particular:

76.2 mm = exactly 3 inches

and:

7.92 mm ≈ 5/16 inch

This can be important when searching for alternatives because the seal may be used in machinery or assemblies originally designed around imperial dimensions.

It should not be replaced by the nearest metric size without technical confirmation of compatibility.

CORTECO 19034392 vs Standard 76x89x8 Oil Seal

A standard seal described as:

76x89x8 mm

should not automatically be considered interchangeable.

CORTECO 19034392 has precise dimensions of:

76.2x89.03x7.92 mm

and the specification:

NBR + VB profile

When comparing an alternative, verify:

• exact shaft diameter,
• exact housing diameter,
• width,
• material,
• profile,
• complete seal geometry.

Can NBR Be Replaced by FPM?

Not automatically.

NBR and FPM belong to different elastomer families and have different operating characteristics.

When considering a material change, verify:

• operating medium,
• temperature,
• speed,
• seal construction,
• profile,
• equipment manufacturer requirements.

FPM is not automatically a correct replacement simply because it may offer higher resistance in certain operating conditions.

The complete sealing geometry and application requirements remain important.

How to Select a Replacement for CORTECO 19034392

Verify:

• reference: 19034392 / 19034392B
• commercial number: 82034392
• inner diameter: 76.2 mm
• outer diameter: 89.03 mm
• width: 7.92 mm
• material: NBR
• profile: VB
• complete seal geometry.

For CATERPILLAR applications, also verify:

OE 5P0064

Selection by the complete CORTECO reference or confirmed OE number is more reliable than searching solely by rounded dimensions.

Installation Recommendations

Before installation, clean and inspect the shaft and housing.

Check:

• shaft contact surface condition,
• absence of burrs,
• absence of sharp edges,
• absence of corrosion,
• housing condition,
• absence of excessive wear,
• correct seal orientation.

The seal should be installed evenly using an appropriate installation tool.

Particular attention should be paid to the exact shaft and housing dimensions. This product should not be treated as a standard metric 76x89x8 mm oil seal.
