Technical data - CORTECO 19016574

CORTECO 19016574 - precise product identification

The complete product designation is:

CORTECO 19016574 ACM LHTB5Y 35x48/56x13/15 mm

For this particular seal, the complete designation is especially important because its geometry cannot be accurately described by only three conventional dimensions.

The identification includes:

• CORTECO - manufacturer
• 19016574 - manufacturer part number
• ACM - elastomer material
• LHTB5Y - seal construction
• 35 mm - nominal inside diameter
• 48/56 mm - compound outside dimensions
• 13/15 mm - compound axial dimensions

When selecting a replacement, the complete 35x48/56x13/15 mm specification should be compared.

Dimensions of CORTECO 19016574

The complete catalogue dimensions are:

35x48/56x13/15 mm

This is a seal with a more complex geometry than a conventional radial shaft seal specified by only:

d x D x b

The catalogue dimensions include:

• 35 mm - nominal inside diameter
• 48/56 mm - compound outside dimensions
• 13/15 mm - compound axial dimensions

The full dimensional specification should not be reduced to:

35x48x13 mm

because this would omit important elements of the seal geometry.

Why is 35x48/56x13/15 mm important?

A conventional radial shaft oil seal is often identified by three dimensions:

inside diameter x outside diameter x width

CORTECO 19016574 uses a more complex construction.

For this reason, the catalogue specifies:

35x48/56x13/15 mm

Both the additional outside dimension and the additional axial dimension are relevant when identifying the seal.

A conventional:

35x48x13 oil seal

should therefore not automatically be considered equivalent to:

CORTECO 19016574 35x48/56x13/15 mm

ACM - Polyacrylate Rubber

CORTECO 19016574 is manufactured from:

ACM - Polyacrylate Rubber

ACM is an elastomer used extensively in automotive sealing technology, including appropriately designed applications involving lubricating oils and elevated operating temperatures.

The material is an integral part of the technical specification.

Seal selection should consider:

• operating medium
• operating temperature
• shaft speed
• sealing system design
• mating surface
• original equipment requirements

ACM vs NBR

ACM and NBR are different elastomer materials.

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

A seal manufactured from NBR should therefore not automatically be considered a replacement for CORTECO 19016574 simply because its dimensions are similar.

If the original specification requires:

CORTECO 19016574 ACM

the material should remain an important selection criterion.

ACM vs FKM/FPM

FKM/FPM belongs to the fluoroelastomer family and has different characteristics from ACM.

Identical dimensions do not establish material equivalence.

Before changing the elastomer type, verify:

• operating medium
• temperature
• shaft speed
• application requirements
• original equipment specification

What does LHTB5Y mean?

LHTB5Y is the specific CORTECO construction designation for part number 19016574.

For technical identification, the complete designation should therefore be retained:

CORTECO 19016574 ACM LHTB5Y

or:

LHTB5Y 35x48/56x13/15 mm

The LHTB5Y designation helps distinguish this product from radial shaft seals with similar basic dimensions but different constructions.

LHTB5Y vs standard TC oil seal

CORTECO 19016574 should not be described simply as a conventional TC oil seal.

The manufacturer specifies the more precise construction:

LHTB5Y

Combined with the unusual:

35x48/56x13/15 mm

geometry, this is an important technical identification feature.

A standard TC oil seal for a 35 mm shaft is therefore not automatically equivalent to CORTECO 19016574.

Multi-stage seal geometry

One of the most important characteristics of CORTECO 19016574 is its compound geometry.

The specification:

35x48/56x13/15 mm

indicates that the product cannot be correctly represented as a conventional cylindrical seal with one outside diameter and one width.

This distinction is particularly important when:

• measuring the original seal
• searching by dimensions
• comparing aftermarket alternatives
• checking the housing geometry
• selecting an equivalent seal

The complete geometry should always be considered.

CORTECO 19016574 - MAZDA applications

CORTECO 19016574 is catalogued for specific:

MAZDA

applications.

The vehicle manufacturer information is useful for product identification, but it does not mean that this seal fits every MAZDA vehicle.

Before installation, verify:

• exact vehicle model
• production year
• engine
• transmission or drivetrain version
• installation position
• OE reference
• original seal part number

Why is searching for 35x48 oil seal not enough?

A search for:

35x48 oil seal

is too broad to identify CORTECO 19016574 accurately.

The complete product geometry is:

35x48/56x13/15 mm

Other seals within the same dimensional group may have:

• different widths
• different outside geometries
• different seal profiles
• different elastomer materials
• different applications

The CORTECO manufacturer reference:

19016574

is therefore the most precise primary identifier.

CORTECO 19016574 vs standard 35x48x13 oil seal

A standard:

35x48x13 mm oil seal

should not automatically be used as a replacement for:

CORTECO 19016574 ACM LHTB5Y 35x48/56x13/15 mm

Although some basic dimensions appear similar, the complete geometry differs.

CORTECO 19016574 incorporates:

• compound 48/56 mm outside dimensions
• compound 13/15 mm axial dimensions
• ACM material
• LHTB5Y construction

These characteristics should be considered together when selecting an equivalent product.

CORTECO 19016574 vs CORTECO 19035160

Another CORTECO seal is catalogued as:

CORTECO 19035160 ACM LHTB5Y 35x48x12/23 mm

Both products:

• use ACM material
• use the LHTB5Y construction designation
• have a 35 mm inside diameter
• are associated with MAZDA applications

However, they are not the same seal.

CORTECO 19016574 has dimensions:

35x48/56x13/15 mm

while CORTECO 19035160 has dimensions:

35x48x12/23 mm

This demonstrates why the complete CORTECO part number and full dimensional specification should always be checked.

Why dimensions alone are not enough

Radial shaft seals with similar basic dimensions can differ in:

• elastomer material
• seal construction
• lip geometry
• outside diameter geometry
• axial geometry
• additional sealing elements
• installation arrangement
• intended application

For CORTECO 19016574, both the manufacturer part number and the complete 35x48/56x13/15 mm geometry are particularly important.

How to select a replacement for CORTECO 19016574

Before selecting an equivalent seal, verify:

• CORTECO part number 19016574
• ACM material
• LHTB5Y construction
• 35 mm inside diameter
• complete 48/56 mm outside geometry
• complete 13/15 mm axial geometry
• installation position
• OE reference
• operating medium
• operating temperature
• shaft speed
• mating surface condition

Matching only the 35 mm inside diameter and 48 mm basic outside diameter does not establish technical interchangeability.

Alternative designations and search terms

The product may be searched for as:

• CORTECO 19016574
• 19016574 CORTECO
• CORTECO 19016574 ACM
• CORTECO 19016574 LHTB5Y

• LHTB5Y 35x48/56x13/15
• ACM LHTB5Y 35x48/56x13/15
• oil seal 35x48/56x13/15
• shaft seal 35x48/56x13/15
• radial shaft seal 35x48/56x13/15
• ACM oil seal 35x48/56x13/15
• MAZDA oil seal 35x48/56x13/15
• MAZDA shaft seal 35x48/56x13/15
• MAZDA Simmerring 35x48/56x13/15
• CORTECO MAZDA oil seal

These are natural search and identification variants. They do not independently establish interchangeability or compatibility with a specific vehicle.

Installation of CORTECO 19016574

Because of the specialised geometry of this seal, the new component should be carefully compared with the removed seal before installation.

Verify:

• installation orientation
• installation depth
• housing geometry
• shaft surface
• stepped outside geometry
• axial positioning

The shaft and housing should be thoroughly cleaned before assembly.

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

Avoid applying installation force directly to functional sealing elements.

Protect the sealing elements during installation

During installation, avoid pulling the functional sealing surfaces across:

• sharp edges
• threads
• splines
• burrs
• damaged surfaces

Where required, use a suitable installation sleeve or tool.

Damage during assembly can result in leakage even when the correct seal has been selected.

Check the mating surface

Before installing a new CORTECO 19016574 seal, inspect the mating surface for:

• wear grooves
• scratches
• corrosion
• irregularities
• burrs
• excessive wear

If the mating surface is damaged, replacing the Simmerring alone may not eliminate the source of leakage.

Why can a new oil seal leak?

Leakage after replacement does not necessarily mean that the new seal is defective.

Possible causes include:

• worn mating surface
• incorrect seal construction
• incorrect material
• incorrect installation depth
• damaged sealing element
• seal misalignment
• housing damage
• incorrect application

For this reason, the complete sealing system should be inspected if leakage occurs repeatedly.
