Technical data - CORTECO 19016575

CORTECO 19016575 - precise product identification

The complete product designation:

CORTECO 19016575 VMQ LHTC 80x105x13 mm

provides the key information required for accurate identification.

When selecting this seal or a replacement, verify:

• CORTECO part number 19016575
• dimensions 80x105x13 mm
• VMQ material
• LHTC profile
• additional dust lip
• crankshaft application
• MAZDA OE reference 045311399
• design of the original seal
• directional requirements where applicable

Dimensions alone should not be used as the only criterion for selecting a replacement.

Dimensions of CORTECO 19016575

The nominal dimensions are:

80x105x13 mm

where:

• 80 mm - inside diameter
• 105 mm - outside diameter
• 13 mm - width

The inside diameter corresponds to the nominal shaft sealing diameter.

The outside diameter corresponds to the nominal housing bore.

The 13 mm width is another essential parameter that should be verified before installation.

VMQ - Silicone Rubber

CORTECO 19016575 is manufactured from:

VMQ - silicone rubber

VMQ belongs to the silicone elastomer family used in technical sealing applications.

Silicone rubber is known for maintaining flexibility over a broad temperature range and is used in appropriately designed automotive sealing systems.

Correct material selection nevertheless depends on factors including:

• operating temperature
• operating medium
• shaft speed
• lubrication conditions
• seal construction
• requirements of the specific application

VMQ should therefore be treated as an integral part of the technical specification of CORTECO 19016575.

VMQ or MVQ - which designation is correct?

The standard technical designation for methyl-vinyl silicone rubber is:

VMQ

The alternative form:

MVQ

can sometimes be encountered in commercial descriptions, older databases or user searches.

For technical product identification, the preferred designation is:

VMQ - silicone rubber

Both variants may nevertheless appear in search queries for this product.

VMQ vs NBR

VMQ and NBR are different elastomer families.

NBR is widely used in conventional oil and grease sealing applications, while VMQ is a silicone elastomer with different thermal and mechanical characteristics.

Therefore:

NBR 80x105x13 is not automatically equivalent to VMQ 80x105x13.

Identical dimensions do not establish material compatibility or technical interchangeability.

VMQ vs ACM

VMQ and ACM are also different materials.

ACM is polyacrylate rubber, while VMQ belongs to the silicone rubber family.

Both materials can be found in automotive radial shaft seals, but they are selected according to the requirements of a particular sealing system.

An ACM seal should therefore not automatically replace CORTECO 19016575 VMQ solely because its dimensions are 80x105x13 mm.

VMQ vs FKM/FPM

VMQ is also different from FKM/FPM.

FKM/FPM refers to fluoroelastomer materials with different chemical, thermal and mechanical properties from VMQ silicone rubber.

When replacing CORTECO 19016575, the specified material should be retained unless an alternative material has been technically approved for the same operating conditions.

What does LHTC mean?

LHTC is the CORTECO profile designation for this particular radial shaft seal construction.

The complete identification is:

CORTECO 19016575 VMQ LHTC 80x105x13 mm

The profile designation is important because two radial shaft seals with identical dimensions can have different working-lip geometries and construction characteristics.

LHTC should therefore be considered when selecting an equivalent seal.

LHTC vs RHTC

CORTECO radial shaft seal catalogues can include profile designations such as LHTC and RHTC.

They should not automatically be treated as interchangeable.

Where the original product is specified as:

LHTC

any proposed replacement should also be checked for the appropriate seal construction and directional characteristics.

This is particularly important in crankshaft applications where the working-lip design may be related to the intended direction of shaft rotation.

Additional dust lip

CORTECO 19016575 incorporates an:

additional dust lip

The dust lip helps protect the primary sealing area against contaminants approaching from the external side.

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

• dust
• dirt
• fine particles
• external contamination

The additional dust lip is an important construction feature and should be considered when comparing CORTECO 19016575 with other 80x105x13 mm radial shaft seals.

CORTECO 19016575 as a crankshaft oil seal

CORTECO 19016575 is catalogued for specific applications as a:

crankshaft radial shaft oil seal

A crankshaft seal operates where the rotating crankshaft passes through the engine housing.

Its function is to maintain separation between the lubricated internal area and the external environment while allowing continuous shaft rotation.

In a crankshaft application, correct selection depends on more than nominal dimensions.

Important factors include:

• seal material
• working-lip geometry
• profile
• directional characteristics
• shaft surface condition
• operating temperature
• lubricant
• correct installation

MAZDA 045311399

CORTECO 19016575 is associated with the OE reference:

MAZDA 045311399

The OE reference is an important identifier when selecting automotive sealing components.

Natural search variants include:

• MAZDA 045311399
• 045311399 seal
• 045311399 oil seal
• 045311399 crankshaft seal
• 045311399 CORTECO
• CORTECO 19016575 MAZDA
• MAZDA crankshaft seal 80x105x13
• MAZDA oil seal 80x105x13

Compatibility should always be verified against the exact vehicle, engine and technical configuration before installation.

Why is the OE reference important?

Many technically different radial shaft seals can have nominal dimensions of 80x105x13 mm.

The OE reference helps connect a particular sealing component with the intended vehicle application.

For CORTECO 19016575, the key MAZDA reference is:

045311399

For accurate identification, the strongest combination of parameters is:

19016575 + 80x105x13 + VMQ + LHTC + 045311399

Why are 80x105x13 mm dimensions alone not enough?

Radial shaft seals with the same nominal dimensions can differ in:

• elastomer material
• seal profile
• working-lip geometry
• number of sealing lips
• additional dust lip
• directional characteristics
• intended operating medium
• temperature requirements
• shaft speed capability
• OEM application

Therefore, a generic 80x105x13 mm oil seal is not automatically equivalent to CORTECO 19016575.

How to select a replacement for CORTECO 19016575

Before selecting an equivalent seal, verify:

• CORTECO reference 19016575
• 80 mm inside diameter
• 105 mm outside diameter
• 13 mm width
• VMQ material
• LHTC profile
• additional dust lip
• crankshaft application
• MAZDA OE 045311399
• directional characteristics
• operating medium
• operating temperature
• shaft speed
• shaft sealing surface condition
• original seal construction

Matching 80x105x13 mm dimensions alone does not guarantee technical interchangeability.

Installation of CORTECO 19016575

Before installation, carefully inspect and clean the crankshaft sealing surface and seal housing.

Check for:

• wear grooves
• scratches
• corrosion
• 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 installation.

Protect the sealing lip during installation

The working lip should not be pulled unprotected over:

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

Where necessary, use an appropriate installation sleeve or another suitable protective method.

Even minor damage to the sealing lip during installation can result in leakage despite correct product selection.

Check the crankshaft sealing surface

The condition of the crankshaft surface is critical to sealing performance.

Before installing CORTECO 19016575, inspect the sealing track for:

• wear caused by the previous seal
• grooves
• scratches
• corrosion
• surface irregularities
• mechanical damage

If the shaft sealing surface is significantly worn, simply installing a new oil seal may not eliminate the cause of leakage.
