Technical data - CORTECO 19016635

CORTECO 19016635 - precise product identification

The complete product designation:

CORTECO 19016635 ACM RHTC 30x42x8 mm

provides more precise identification than dimensions alone.

When selecting this seal or an equivalent replacement, verify:

• CORTECO part number 19016635
• dimensions 30x42x8 mm
• ACM material
• RHTC profile
• additional dust lip
• installation position
• OE reference
• operating medium
• operating conditions
• shaft rotation or directional requirements where specified for the particular application

A radial shaft seal should not be selected solely because its dimensions are 30x42x8 mm.

Dimensions of CORTECO 19016635

The nominal dimensions are:

30x42x8 mm

where:

• 30 mm - inside diameter
• 42 mm - outside diameter
• 8 mm - width

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

The outside diameter corresponds to the nominal housing bore.

Although these dimensions are fundamental for identification, they do not define the complete technical specification of the seal.

ACM - Polyacrylate Rubber

CORTECO 19016635 is manufactured from:

ACM - Polyacrylate Rubber

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

Seal material is a critical selection parameter because it affects characteristics including:

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

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

ACM vs NBR

ACM and NBR are different elastomer families.

NBR is widely used in general oil and grease sealing applications, while ACM is frequently selected for automotive sealing applications where the specific properties of polyacrylate rubber are required.

Material selection depends on factors including:

• operating medium
• operating temperature
• shaft speed
• seal design
• installation environment
• vehicle or equipment manufacturer requirements

Matching dimensions do not establish material equivalence.

ACM vs FKM/FPM

ACM and FKM/FPM are also different elastomer materials.

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

Therefore:

ACM is not the same material as FKM/FPM.

A 30x42x8 mm FKM seal should not automatically be considered a direct replacement for CORTECO 19016635 ACM.

The material specified for the original application should be retained unless an alternative has been technically validated.

What does RHTC mean?

RHTC is the CORTECO construction designation for this particular radial shaft seal execution.

For CORTECO 19016635, an important construction characteristic is the:

additional dust lip

The RHTC designation should therefore be treated as an integral part of the complete product identification.

Instead of identifying the product only as:

30x42x8 oil seal

the more precise identification is:

CORTECO 19016635 ACM RHTC 30x42x8 mm

Additional dust lip

CORTECO 19016635 incorporates an additional dust lip.

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

Depending on the installation environment, this may help limit exposure to:

• dust
• dirt
• fine particles
• external contamination

The presence of the dust lip is an important construction feature when comparing CORTECO 19016635 with simpler radial shaft seals of the same dimensions.

CORTECO 19016635 as a crankshaft oil seal

In specific catalogued applications, CORTECO 19016635 is used as a:

crankshaft radial shaft seal

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

Correct identification is particularly important because a seal of the same dimensions may differ in material, lip geometry or directional characteristics.

Compatibility should therefore be verified against the exact OE reference and vehicle application.

CORTECO 19016635 as a differential seal

CORTECO 19016635 is also catalogued in specific applications as a:

differential shaft seal

In this application, the seal operates as part of the transmission or differential sealing system.

Relevant searches may therefore include:

• CORTECO 19016635 differential seal
• differential oil seal 30x42x8
• differential shaft seal 30x42x8
• RHTC differential seal
• ACM differential seal 30x42x8

These search descriptions refer to the product only where the corresponding application is confirmed for the specific vehicle.

CORTECO 19016635 as a gearbox shaft seal

The same CORTECO reference may also be catalogued as a:

gearbox shaft oil seal

In this application, the sealing lip operates against a rotating transmission shaft.

When selecting the seal for a gearbox application, verify:

• installation position
• OE reference
• ACM material
• RHTC construction
• shaft diameter
• housing diameter
• width
• original seal design

A dimensional match alone does not confirm suitability for a particular transmission.

HONDA application

For specific HONDA applications, CORTECO 19016635 is associated with OE reference:

HONDA 91212679014

Natural search variants include:

• HONDA 91212679014
• 91212679014 oil seal
• 91212679014 shaft seal
• 91212679014 CORTECO
• CORTECO 19016635 HONDA
• HONDA oil seal 30x42x8
• HONDA shaft seal 30x42x8
• HONDA Simmerring 30x42x8

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

TOYOTA application

For specific TOYOTA applications, CORTECO 19016635 is associated with OE reference:

TOYOTA 9031130002

Natural search variants include:

• TOYOTA 9031130002
• 9031130002 oil seal
• 9031130002 shaft seal
• 9031130002 CORTECO
• CORTECO 19016635 TOYOTA
• TOYOTA oil seal 30x42x8
• TOYOTA shaft seal 30x42x8

The OE number is an important part of precise product identification.

Why can one seal 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 19016635 may appear in catalogues as a seal for:

• crankshaft
• differential
• gearbox shaft

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

The exact catalogue assignment must always be checked for the specific application.

Why are 30x42x8 mm dimensions alone not enough?

Different radial shaft seals can share the same nominal dimensions.

A 30x42x8 mm seal may differ from another 30x42x8 mm seal in:

• elastomer material
• sealing profile
• primary lip geometry
• dust lip
• directional characteristics
• spring configuration
• intended operating medium
• application
• OEM specification

Therefore, not every 30x42x8 mm oil seal is technically equivalent to CORTECO 19016635.

How to select a replacement for CORTECO 19016635

Before selecting an equivalent seal, verify:

• CORTECO reference 19016635
• 30 mm inside diameter
• 42 mm outside diameter
• 8 mm width
• ACM material
• RHTC profile
• additional dust lip
• installation position
• HONDA or TOYOTA OE reference where applicable
• operating medium
• operating temperature
• shaft speed
• shaft surface condition
• vehicle or equipment manufacturer requirements

Identical 30x42x8 mm dimensions alone do not guarantee technical interchangeability.

Selecting the correct radial shaft seal

Correct radial shaft seal selection requires more than matching three dimensions.

Important parameters include:

• shaft diameter
• housing bore diameter
• seal width
• elastomer material
• lip design
• additional dust lip
• directional characteristics
• shaft speed
• operating temperature
• operating medium
• pressure conditions
• shaft surface finish
• installation environment
• OEM requirements

For automotive applications, the OE reference and exact vehicle configuration should also be checked.

Installation of CORTECO 19016635

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

Check for:

• wear grooves
• corrosion
• scratches
• sharp edges
• contamination
• damaged housing surfaces
• incorrect seating surfaces

The seal should be pressed into position evenly using a suitable installation tool.

Avoid tilting, twisting or deforming the seal during installation.

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, use an appropriate installation sleeve or protective method.

Damage to the sealing lip during assembly can cause leakage even when the correct seal has been selected.

Check the shaft sealing surface

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

Before fitting a new CORTECO 19016635, inspect the sealing track for:

• wear grooves
• scratches
• corrosion
• mechanical damage
• contamination
• irregularities

If the mating surface is significantly worn, simply replacing the seal may not solve the leakage problem.

The complete sealing arrangement should be evaluated.
