Technical data - CORTECO 19016572

CORTECO 19016572 - precise product identification

The complete designation:

CORTECO 19016572 ACM RHTC 40x55x8 mm

identifies much more than the nominal dimensions of the seal.

When selecting this product or an equivalent replacement, verify:

• CORTECO part number 19016572
• alternative catalogue reference 19016572B
• 40x55x8 mm dimensions
• ACM material
• RHTC profile
• additional dust lip
• right-hand directional design
• installation position
• corresponding OE number
• operating conditions

A seal should not be selected solely because its dimensions are 40x55x8 mm.

Dimensions of CORTECO 19016572

The nominal dimensions are:

40x55x8 mm

where:

• 40 mm - inside diameter
• 55 mm - outside diameter
• 8 mm - width

The 40 mm inside diameter corresponds to the nominal shaft sealing diameter, while the 55 mm outside diameter corresponds to the nominal housing bore.

These dimensions are essential for identification but do not define the complete technical specification.

ACM - Polyacrylate Rubber

CORTECO 19016572 is manufactured from:

ACM - Polyacrylate Rubber

ACM is an elastomer widely used in automotive sealing technology, including applications involving lubricants and elevated operating temperatures where the characteristics of polyacrylate rubber are appropriate.

Seal material is a critical selection parameter because it influences characteristics such as:

• resistance to operating fluids
• temperature behaviour
• ageing resistance
• flexibility
• long-term sealing performance

An ACM seal should not automatically be replaced by an NBR, FKM/FPM or VMQ version simply because the dimensions are identical.

ACM vs NBR

ACM and NBR are different elastomer families.

NBR is widely used for general oil and grease sealing applications, while ACM is frequently selected for automotive sealing systems requiring the specific characteristics of polyacrylate rubber.

The correct material depends on factors including:

• lubricant or operating medium
• operating temperature
• shaft speed
• seal construction
• installation environment
• vehicle manufacturer requirements

Matching 40x55x8 mm dimensions do not establish material equivalence.

ACM vs FKM/FPM

ACM and FKM/FPM are also technically different elastomer materials.

FKM/FPM is generally selected for a different range of thermal and chemical requirements.

Therefore:

ACM is not the same material as FKM/FPM.

A 40x55x8 mm FKM seal should not automatically be considered a replacement for CORTECO 19016572 ACM.

What does RHTC mean?

RHTC is the CORTECO profile designation for this particular seal construction.

For CORTECO 19016572, important characteristics include:

• RHTC profile
• additional dust lip
• right-hand directional design

The profile should therefore be treated as an integral part of product identification.

Instead of searching only for:

40x55x8 oil seal

the more precise identification is:

CORTECO 19016572 ACM RHTC 40x55x8 mm

Additional dust lip

CORTECO 19016572 incorporates an additional dust lip.

Its purpose is to help protect the primary sealing area from external contaminants.

Depending on the installation environment, the dust lip can help limit exposure to:

• dust
• dirt
• fine particles
• external contamination

The dust lip is an important construction feature when comparing this product with simpler single-lip 40x55x8 mm seals.

Right-hand directional sealing design

CORTECO 19016572 is catalogued with a:

right-hand directional design

Directional characteristics can be important in radial shaft seals designed for rotating shafts.

The geometry of the sealing area may be designed to interact with shaft rotation and support the sealing function.

For this reason, a seal with the same 40x55x8 mm dimensions but a different directional design should not automatically be treated as technically interchangeable.

CORTECO 19016572 as a camshaft seal

In specific catalogued applications, CORTECO 19016572 is used as a:

camshaft oil seal

The seal operates where the rotating camshaft passes through the engine housing or cylinder head sealing area.

Correct selection should be based on the exact vehicle application and OE reference rather than dimensions alone.

Search terms associated with this application include:

• camshaft seal 40x55x8
• camshaft oil seal 40x55x8
• CORTECO 19016572 camshaft seal
• ACM camshaft seal 40x55x8
• RHTC camshaft seal

CORTECO 19016572 as a crankshaft seal

In other catalogued applications, CORTECO 19016572 is used as a:

crankshaft oil seal

A crankshaft seal controls lubricant at the point where the rotating crankshaft passes through the engine housing.

For this application, the complete seal specification is important, including material, lip construction and directional design.

Relevant search variants include:

• crankshaft seal 40x55x8
• crankshaft oil seal 40x55x8
• CORTECO 19016572 crankshaft seal
• ACM crankshaft seal 40x55x8

CORTECO 19016572 as a transfer case seal

Depending on the vehicle configuration, CORTECO 19016572 can also be catalogued as a:

transfer case shaft seal

In this application, the radial shaft seal operates as part of the transfer case sealing system.

Relevant search terms include:

• transfer case seal 40x55x8
• transfer case shaft seal 40x55x8
• transfer case oil seal
• CORTECO 19016572 transfer case seal

This does not mean that CORTECO 19016572 fits every transfer case. Exact catalogue compatibility must be verified.

Why can CORTECO 19016572 have several applications?

The same radial shaft seal can be used in different installation positions depending on the design of a particular vehicle or mechanical assembly.

For this reason, CORTECO 19016572 may appear in catalogues as a seal for:

• camshaft
• crankshaft
• transfer case shaft

This does not mean that the seal can be used in all three positions in every vehicle.

The exact catalogue assignment and OE reference should always be checked for the specific application.

Why are 40x55x8 mm dimensions alone not enough?

Many technically different radial shaft seals can share the same nominal dimensions.

Different 40x55x8 mm seals may have different:

• elastomer materials
• sealing profiles
• primary lip geometries
• dust lips
• directional characteristics
• spring configurations
• operating media
• temperature requirements
• OEM applications

Therefore, not every 40x55x8 mm Simmerring or oil seal is technically equivalent to CORTECO 19016572.

How to select a replacement for CORTECO 19016572

Before selecting an equivalent seal, verify:

• CORTECO reference 19016572 / 19016572B
• 40 mm inside diameter
• 55 mm outside diameter
• 8 mm width
• ACM material
• RHTC profile
• additional dust lip
• right-hand directional design
• installation position
• corresponding OE reference
• operating medium
• operating temperature
• shaft speed
• shaft surface condition
• vehicle manufacturer requirements

Matching 40x55x8 mm dimensions alone does not guarantee technical interchangeability.

Installation of CORTECO 19016572

Before installation, carefully inspect and clean the shaft and seal housing.

Check for:

• wear grooves
• corrosion
• scratches
• sharp edges
• contamination
• mechanical damage
• incorrect seating surfaces

The seal should be pressed into position evenly using an appropriate installation tool.

Avoid tilting, twisting or deforming the seal during assembly.

Protect the sealing lip during installation

The sealing lip should not be pulled directly over:

• sharp edges
• threads
• splines
• grooves
• damaged shaft surfaces

Where necessary, an appropriate installation sleeve or protective method should be used.

Even minor damage to the sealing lip during assembly can result in leakage after installation.

Check the shaft sealing surface

The condition of the shaft surface is critical to radial shaft seal performance.

Before installing CORTECO 19016572, inspect the sealing track for:

• wear grooves
• scratches
• corrosion
• mechanical damage
• contamination
• irregular surface condition

If the mating surface is significantly worn or damaged, replacing the seal alone may not eliminate the cause of leakage.
