Technical data - CORTECO 19016486

CORTECO 19016486 - precise product identification

The complete product designation is:

CORTECO 19016486 VMQ LHTC 29x45x8 mm

The main identification parameters are:

• CORTECO - manufacturer
• 19016486 - manufacturer part number
• VMQ - elastomer material
• LHTC - seal construction designation
• 29 mm - inside diameter
• 45 mm - outside diameter
• 8 mm - seal width
• HONDA - vehicle manufacturer associated with specific catalogued applications

Replacement selection should not be based on the 29x45x8 mm dimensions alone.

Dimensions of CORTECO 19016486

The nominal dimensions are:

29x45x8 mm

where:

• inside diameter d: 29 mm
• outside diameter D: 45 mm
• width b: 8 mm

These dimensions should always be considered together with the VMQ material, LHTC construction and CORTECO 19016486 manufacturer reference.

VMQ - Silicone Rubber

CORTECO 19016486 is manufactured from:

VMQ - Silicone Rubber

VMQ belongs to the silicone elastomer family and is used in specialised automotive and industrial sealing applications.

Silicone elastomers can be selected for applications where their particular temperature characteristics and flexibility are beneficial.

Correct material selection should consider:

• operating temperature
• operating medium
• shaft speed
• lubrication conditions
• sealing system design
• original equipment requirements

VMQ or MVQ?

Both:

VMQ

and:

MVQ

can be encountered in commercial and aftermarket terminology for silicone sealing materials.

For this product, VMQ is used as the primary technical material designation.

The alternative MVQ spelling can still be useful as a search variant because it occurs in aftermarket catalogues and product databases.

VMQ vs NBR

VMQ and NBR are different elastomer families.

NBR is nitrile butadiene rubber, while VMQ is silicone rubber.

Therefore:

NBR 29x45x8

should not automatically be considered equivalent to:

CORTECO 19016486 VMQ 29x45x8

simply because the dimensions are identical.

The material specification is an important part of seal selection.

VMQ vs FKM/FPM

VMQ and FKM/FPM are also different elastomer families.

FKM/FPM is a fluoroelastomer, whereas VMQ is a silicone elastomer.

Both material families may be encountered in applications involving elevated temperatures, but their chemical, mechanical and operating characteristics differ.

Changing the material therefore requires verification against the actual operating conditions.

What does LHTC mean?

LHTC is the construction designation shown for CORTECO 19016486 in the dimensional catalogue.

For precise product identification, the complete specification should be retained:

CORTECO 19016486 VMQ LHTC 29x45x8 mm

Directional sealing designs can incorporate features intended for a defined shaft rotation direction.

For this reason, LHTC and RHTC should not automatically be treated as interchangeable versions.

Important note about LHTC / RHTC

Available catalogue material for CORTECO 19016486 contains a discrepancy concerning the LHTC/RHTC designation.

The dimensional catalogue identifies the seal as:

VMQ LHTC 29x45x8 mm

while other commercial catalogue material can identify the same reference as RHTC.

For an application where directional sealing geometry is relevant, verify:

• marking on the original seal
• shaft rotation direction
• OE reference
• application documentation
• geometry of the removed seal

The directional version should not be selected from dimensions alone.

Additional dust lip

Aftermarket catalogue data describes CORTECO 19016486 as having an additional dust lip.

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

Depending on the application, this can help reduce exposure to:

• dust
• dirt
• fine particles
• external contamination

The presence and geometry of the additional lip should also be considered when comparing replacement seals.

CORTECO 19016486 - HONDA applications

CORTECO 19016486 is catalogued for specific:

HONDA

applications.

This does not mean that the seal is compatible with every HONDA vehicle.

Before ordering or installation, verify:

• exact vehicle model
• production year
• engine version
• transmission or drivetrain configuration
• installation position
• OE reference
• reference marked on the removed seal

Application verification is particularly important when directional seal construction is involved.

29x45x8 oil seal - why dimensions alone are not enough

Many sealing products can share the nominal dimensions:

29x45x8 mm

but differ in:

• elastomer material
• sealing lip design
• additional dust lip
• directional geometry
• external construction
• intended application

For this reason, searching only for:

29x45x8 oil seal

is less precise than searching for:

CORTECO 19016486 VMQ LHTC 29x45x8

Directional vs non-directional oil seals

A conventional non-directional radial shaft seal is generally not selected according to shaft rotation direction.

A directional seal can use sealing features designed to interact with shaft rotation.

This means that two seals with identical:

29x45x8 mm

dimensions may not necessarily be functionally equivalent if one has a directional sealing design and the other does not.

For CORTECO 19016486, the construction designation should therefore remain part of the technical identification.

Why the CORTECO part number matters

The manufacturer reference:

19016486

is a much more precise identifier than dimensions alone.

A search for:

oil seal 29x45x8

may return multiple constructions and materials.

A search for:

CORTECO 19016486

identifies the specific CORTECO product family much more precisely.

For procurement and replacement purposes, the manufacturer reference should therefore be retained whenever possible.

How to select a replacement for CORTECO 19016486

Before using an alternative product, verify:

• CORTECO reference 19016486
• 29 mm inside diameter
• 45 mm outside diameter
• 8 mm width
• VMQ silicone material
• seal construction
• directional characteristics
• additional dust lip
• OE reference
• installation position
• shaft rotation direction
• operating medium
• operating temperature

Matching the 29x45x8 mm dimensions alone does not establish full technical interchangeability.

Alternative designations and search terms

The product may be searched for as:

How to identify CORTECO 19016486 correctly

A reliable identification procedure is to:

1. verify CORTECO part number 19016486,
2. confirm dimensions 29x45x8 mm,
3. confirm VMQ material,
4. check the seal construction,
5. verify directional characteristics,
6. compare the seal with the removed component,
7. check the OE reference,
8. confirm the exact vehicle and installation position.

This approach reduces the risk of selecting a dimensionally similar but technically different seal.

Installation of CORTECO 19016486

Before installation, thoroughly clean:

• shaft surface
• seal housing
• surrounding components

Inspect the mating surface for:

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

If the seal uses directional features, the correct version and shaft rotation direction should also be confirmed before installation.

Correct installation of the Simmerring

The seal should be installed:

• evenly
• square to the housing
• without tilting
• using an appropriate installation tool

Installation force should not be applied directly to delicate functional sealing elements.

If the seal must pass over threads, splines or sharp edges, the sealing surfaces should be protected with a suitable installation sleeve.

Check the shaft sealing surface

Before installing the new seal, carefully inspect the shaft surface where the sealing lip operates.

Look for:

• wear tracks
• grooves
• scratches
• corrosion
• surface irregularities
• excessive wear

A damaged shaft surface can cause leakage even when the correct new CORTECO seal has been installed.

Why can a new oil seal leak?

Leakage after replacement does not necessarily indicate a defective seal.

Possible causes include:

• worn shaft surface
• incorrect directional version
• installation damage
• seal misalignment
• incorrect installation depth
• incorrect elastomer material
• unsuitable replacement construction
• damaged housing

If leakage occurs repeatedly, the complete sealing system should be inspected.
