CORTECO 19016051 NBR V4 Seal 23.3x29.75x1.7/4.5 mm Simmerring

CORTECO 19016051 NBR V4 Seal 23.3x29.75x1.7/4.5 mm Simmerring

CORTECO 19016051 NBR V4 23.3x29.75x1.7/4.5 mm is a specialised sealing ring manufactured from NBR nitrile rubber. The product features the CORTECO V4 construction and precise, non-standard dimensions of 23.3x29.75x1.7/4.5 mm. Correct identification should retain the complete CORTECO 19016051 reference, V4 profile, NBR material and all dimensional values without rounding.

Technical data - CORTECO 19016051

CORTECO 19016051 - precise product identification

The complete designation is:

CORTECO 19016051 NBR V4 23.3x29.75x1.7/4.5 mm

This provides considerably more precise identification than searching only by approximate diameter.

The key identification parameters are:

• CORTECO - manufacturer
• 19016051 - manufacturer part number
• NBR - elastomer material
• V4 - construction designation
• 23.3 mm - inside diameter
• 29.75 mm - outside diameter
• 1.7/4.5 mm - compound axial dimensions

For this product, both the decimal values and the complete 1.7/4.5 mm axial specification should be retained.

Dimensions of CORTECO 19016051

The complete dimensional specification is:

23.3x29.75x1.7/4.5 mm

including:

• inside diameter: 23.3 mm
• outside diameter: 29.75 mm
• axial dimensions: 1.7/4.5 mm

This is not a conventional sealing ring that can be accurately identified using three rounded dimensions.

The exact catalogue values should be retained when searching for or comparing replacement products.

Why should the dimensions not be rounded?

Searching for:

23x30x2

or simply:

23x30 seal

is not equivalent to the exact specification:

23.3x29.75x1.7/4.5 mm

In sealing technology, relatively small dimensional differences can affect:

• installation fit
• contact geometry
• sealing performance
• component positioning
• operating reliability
• service life

For CORTECO 19016051, the exact dimensions should therefore be used.

NBR - Nitrile Butadiene Rubber

CORTECO 19016051 is manufactured from:

NBR - Nitrile Butadiene Rubber

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

Depending on the compound and operating conditions, NBR is commonly used in sealing systems involving suitable:

• mineral oils
• lubricating greases
• lubricants

It also provides useful mechanical and wear characteristics for many conventional sealing applications.

The material specification should always be considered together with the actual operating medium and temperature.

NBR vs FKM/FPM

NBR and FKM/FPM belong to different elastomer families.

FKM/FPM fluoroelastomers have different thermal and chemical characteristics from NBR.

Therefore, an:

FKM 23.3x29.75x1.7/4.5 seal

should not automatically be considered equivalent to:

NBR 23.3x29.75x1.7/4.5

simply because the dimensions are identical.

NBR vs ACM

ACM is polyacrylate rubber, while NBR is nitrile butadiene rubber.

These elastomer families have different operating characteristics.

If CORTECO 19016051 is specified in NBR, this material designation should remain part of the replacement selection process.

What does V4 mean?

V4 is the construction designation specified for CORTECO 19016051.

It should therefore be retained as an important part of the complete product identification:

CORTECO 19016051 NBR V4

The V4 designation should not automatically be treated as equivalent to other radial shaft seal construction codes such as:

• SC
• TC
• TC3
• TC5Y
• RHTC
• LHTC

These are different construction designations.

V4 vs standard TC oil seal

CORTECO 19016051 should not automatically be classified as a conventional TC oil seal.

Its specified construction is:

V4

and its dimensions are:

23.3x29.75x1.7/4.5 mm

This differs significantly from the dimensional format of many conventional radial shaft oil seals.

The V4 designation should therefore be retained when searching for a replacement.

Precise 23.3x29.75x1.7/4.5 mm geometry

One of the most important characteristics of CORTECO 19016051 is its precise and unusual geometry.

The difference between the inside and outside diameters is relatively small:

23.3 mm to 29.75 mm

The product also has compound axial dimensions:

1.7/4.5 mm

This makes approximate dimensional matching particularly unsuitable for identifying an equivalent product.

Why is CORTECO 19016051 important as an identifier?

For specialised sealing products with non-standard dimensions, the manufacturer's part number is one of the most useful identifiers.

The most precise search is:

CORTECO 19016051

or:

CORTECO 19016051 NBR V4 23.3x29.75x1.7/4.5 mm

Searching only for:

23x30 seal

is substantially less precise and may return products with different geometry or construction.

Can a 23x30 seal replace 23.3x29.75?

Interchangeability should not be assumed.

The difference between:

23.3x29.75 mm

and:

23x30 mm

may appear small, but dimensional tolerances and component geometry are important in sealing systems.

CORTECO 19016051 additionally has:

• V4 construction
• NBR material
• compound 1.7/4.5 mm axial dimensions

All of these parameters should be considered.

Is 23.3x29.75x1.7 the complete dimension?

No.

The complete dimensional designation is:

23.3x29.75x1.7/4.5 mm

Omitting the 4.5 mm value removes part of the information describing the product geometry.

The complete specification should be retained when ordering or comparing alternatives.

How to select a replacement for CORTECO 19016051

Before selecting an alternative product, verify:

• CORTECO part number 19016051
• NBR material
• V4 construction
• 23.3 mm inside diameter
• 29.75 mm outside diameter
• 1.7 mm axial dimension
• 4.5 mm additional axial dimension
• complete seal geometry
• installation position
• operating medium
• operating conditions

Approximate dimensional similarity does not establish technical interchangeability.

Alternative designations and search terms

The product may be searched for as:

• CORTECO 19016051
• 19016051 CORTECO
• CORTECO 19016051 NBR
• CORTECO 19016051 V4

• NBR V4 23.3x29.75x1.7/4.5
• V4 23.3x29.75x1.7/4.5
• seal 23.3x29.75x1.7/4.5
• sealing ring 23.3x29.75x1.7/4.5
• oil seal 23.3x29.75x1.7/4.5
• NBR seal 23.3x29.75x1.7/4.5
• CORTECO V4 seal
• V4 NBR seal
• 23.3 mm shaft seal
• 29.75 mm sealing ring

These are natural search and identification variants. They do not independently establish technical interchangeability.

How to identify CORTECO 19016051 correctly

A reliable identification process is to:

1. verify CORTECO part number 19016051,
2. confirm V4 construction,
3. confirm NBR material,
4. verify the 23.3 mm dimension,
5. verify the 29.75 mm dimension,
6. verify the complete 1.7/4.5 mm axial specification,
7. compare the geometry with the removed component,
8. confirm the intended application.

This approach reduces the risk of selecting a product that appears dimensionally similar but differs in construction.

Installation of CORTECO 19016051

Before installation, carefully inspect:

• mating surfaces
• seal housing
• installation orientation
• seal position
• adjacent components

Because of the small and precise dimensions, excessive installation force should be avoided.

The sealing element should be installed evenly using a suitable tool without deforming its functional surfaces.

Protect the seal during installation

During installation, protect the sealing element against:

• sharp edges
• burrs
• threads
• damaged surfaces
• excessive stretching
• deformation

Installation damage can cause leakage even when the correct CORTECO reference has been selected.

Check the mating surfaces

Before installing the new seal, inspect the mating surfaces for:

• wear
• scratches
• corrosion
• irregularities
• contamination
• mechanical damage

If the mating component is damaged, replacing the sealing ring alone may not solve the leakage problem.
