Technical data - CORTECO 19016537

CORTECO 19016537 - precise product identification

The complete designation is:

CORTECO 19016537 ACM TC3 45x68x12 mm

This designation contains the essential information required to identify the seal correctly:

• CORTECO - manufacturer
• 19016537 - manufacturer part number
• ACM - elastomer material
• TC3 - seal construction
• 45 mm - inside diameter
• 68 mm - outside diameter
• 12 mm - width

When searching for a replacement, the complete technical specification should be compared rather than the dimensions alone.

Dimensions of CORTECO 19016537

The nominal dimensions are:

45x68x12 mm

where:

• 45 mm - inside diameter d
• 68 mm - outside diameter D
• 12 mm - width b

The inside diameter corresponds to the nominal diameter of the shaft sealing surface.

The outside diameter corresponds to the nominal housing bore.

The 12 mm value defines the axial width of the seal.

ACM - Polyacrylate Rubber

CORTECO 19016537 is manufactured from:

ACM - Polyacrylate Rubber

ACM is an elastomer widely used in automotive and industrial sealing technology, particularly in appropriately designed systems involving lubricating oils and elevated operating temperatures.

Seal material is an important selection parameter and should be considered together with:

• operating medium
• temperature
• shaft speed
• sealing surface
• operating environment
• original seal specification

The ACM designation should therefore not be ignored when selecting an equivalent product.

ACM vs NBR

A:

45x68x12 ACM oil seal

and a:

45x68x12 NBR oil seal

can have identical dimensions but are not necessarily technically equivalent.

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

These elastomers have different operating characteristics.

If the original application specifies ACM, an NBR seal should not automatically be selected solely because its dimensions are identical.

ACM vs FKM/FPM

The same principle applies to FKM/FPM.

FKM/FPM belongs to the fluoroelastomer family, whereas ACM is a polyacrylate elastomer.

Therefore:

ACM 45x68x12

and:

FKM/FPM 45x68x12

should not automatically be considered interchangeable.

Material compatibility must be evaluated for the actual operating conditions.

What does TC3 mean on CORTECO 19016537?

TC3 is the construction designation specified for CORTECO 19016537.

For accurate technical identification, the complete specification should therefore be retained:

ACM TC3 45x68x12

The TC3 designation should not automatically be simplified to a generic TC profile when selecting a replacement.

Oil seals with the same 45x68x12 mm dimensions may differ in construction, sealing lip geometry, material and intended application.

TC3 vs generic TC oil seal

International oil seal terminology frequently uses the designation TC for a common double-lip radial shaft seal construction.

However, CORTECO 19016537 is specifically catalogued with the construction designation:

TC3

For this reason, TC3 should be retained in the technical product identification.

A generic:

TC 45x68x12

should not automatically be treated as technically identical to:

CORTECO 19016537 ACM TC3 45x68x12

without confirming the construction and application requirements.

CORTECO 19016537 vs other 45x68x12 oil seals

The dimensions:

45x68x12 mm

can occur in many different radial shaft seals.

Products sharing these dimensions can differ in:

• elastomer material
• seal construction
• sealing lip geometry
• outside diameter design
• additional sealing elements
• manufacturer-specific profile
• intended application

This is why the CORTECO part number:

19016537

is an important element of product identification.

CORTECO 19016537 - DAIHATSU applications

The CORTECO dimensional catalogue associates:

19016537 ACM TC3 45x68x12

with:

DAIHATSU

This information helps identify the product but does not mean that the seal is suitable for every DAIHATSU vehicle.

Before installation in a specific vehicle, verify:

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

Vehicle-specific compatibility should always be confirmed from the relevant application catalogue.

Why is the CORTECO part number important?

Searching only for:

45x68x12 oil seal

can return multiple products with different technical specifications.

Searching for:

CORTECO 19016537 ACM TC3 45x68x12

provides much more precise product identification.

This is particularly important in automotive applications, where seals of identical dimensions may use different elastomers and construction profiles.

How to select a replacement for CORTECO 19016537

Before selecting an alternative, verify:

• CORTECO part number 19016537
• inside diameter 45 mm
• outside diameter 68 mm
• width 12 mm
• ACM material
• TC3 construction
• operating medium
• operating temperature
• shaft speed
• shaft sealing surface
• installation position
• OE number of the original component

Matching the 45x68x12 mm dimensions alone does not establish technical interchangeability.

Installation of CORTECO 19016537

Before installation, carefully clean and inspect:

• shaft sealing surface
• seal housing
• surrounding components

Check the shaft for:

• wear grooves
• scratches
• corrosion
• burrs
• sharp edges
• mechanical damage

The seal should be pressed squarely and evenly into the housing using an appropriate installation tool.

Avoid tilting or deforming the seal during installation.

Protect the sealing lip during installation

The functional sealing area should be protected from contact with:

• sharp edges
• threads
• splines
• grooves
• burrs

Where necessary, use a suitable installation sleeve to protect the sealing lip as it passes over potentially damaging shaft features.

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

Check the shaft sealing surface

The condition of the shaft surface directly beneath the sealing lip is critical.

Before fitting a new seal, inspect for:

• wear tracks
• grooves from the previous seal
• scratches
• corrosion
• excessive wear
• surface damage

If the shaft sealing track is damaged, replacing the oil seal alone may not eliminate the leakage.

Why can a new oil seal leak?

Leakage after installation does not necessarily indicate a defective seal.

Possible causes include:

• worn shaft surface
• incorrect seal material
• incorrect seal construction
• damaged sealing lip
• incorrect installation
• seal misalignment
• damaged housing
• unsuitable operating conditions

The complete sealing system should therefore be inspected when diagnosing repeated leakage.
