The complete technical identification is:

CORTECO 20018100 FPM BASLRDX7 35x50x7 mm

CORTECO 20018100 Dimensions

The nominal dimensions are:

35x50x7 mm

where:

• 35 mm - inside diameter
• 50 mm - outside diameter
• 7 mm - seal width

Dimensions alone are not sufficient to determine interchangeability.

Many rotary shaft seals are manufactured in the popular 35x50x7 mm size but may differ in elastomer, sealing-lip design, dust lip, outer surface and hydrodynamic features.

Therefore, two 35x50x7 oil seals should not automatically be considered interchangeable.

FPM Fluoroelastomer

CORTECO 20018100 is manufactured from FPM fluoroelastomer.

FPM belongs to the fluoroelastomer family, also commonly designated FKM.

Suitable FPM/FKM compounds are widely used for demanding rotary sealing applications because of their resistance to:

• many engine and transmission oils
• many lubricating greases
• elevated temperatures
• many fuels and hydrocarbons
• ozone
• ageing
• demanding operating environments

Exact chemical compatibility and temperature capability depend on the specific compound and operating medium.

A universal temperature range should therefore not be assigned to every FPM seal without the corresponding manufacturer specification.

FPM, FKM and Viton - what is the difference?

FPM and FKM are designations associated with the fluoroelastomer material family.

Viton is a trademark used for particular fluoroelastomer products and should not automatically be used as a generic material name for every FPM/FKM seal.

For CORTECO 20018100, the verified material designation is FPM.

What does BASLRDX7 mean?

BASLRDX7 identifies the CORTECO seal design.

When selecting an equivalent, the 35x50x7 mm dimensions are only part of the specification.

Important characteristics also include:

• main sealing-lip construction
• additional dust lip
• FPM material
• right-hand hydrodynamic structure
• complete seal geometry

A generic 35x50x7 rotary shaft seal should therefore not automatically be considered equivalent to CORTECO 20018100 BASLRDX7.

Additional Dust Lip

CORTECO 20018100 features an additional dust lip.

The dust lip helps reduce the ingress of external contamination into the area of the primary sealing lip.

It can provide additional protection against:

• dust
• fine dirt
• particles
• external contamination

The presence of the dust lip is an important construction feature and should be considered when selecting a replacement seal.

Right-Hand Hydrodynamic Structure

CORTECO 20018100 is catalogued with a right-hand hydrodynamic structure.

Directional hydrodynamic features are used on certain rotary shaft seals to support sealing performance when the shaft rotates in the intended direction.

The direction of rotation can therefore be relevant when selecting a replacement.

A right-hand seal should not automatically be replaced by a left-hand version or by a different seal design solely because the nominal dimensions are identical.

CORTECO 20018100 Crankshaft Seal

One of the principal applications associated with CORTECO 20018100 is a crankshaft oil seal.

Crankshaft seals operate under demanding conditions involving:

• continuous shaft rotation
• contact with lubricant
• engine operating temperatures
• long operating periods
• prevention of oil leakage

The FPM material, sealing-lip design and hydrodynamic structure are therefore important characteristics of this seal.

CORTECO 20018100 Camshaft Seal

CORTECO 20018100 is also catalogued for camshaft sealing applications.

When selecting a camshaft seal, verify:

• shaft diameter
• housing diameter
• seal width
• FPM material
• BASLRDX7 construction
• direction of rotation
• dust lip
• OE reference

Do not select a camshaft seal only because its dimensions are 35x50x7 mm.

Intermediate Shaft Seal

Depending on the vehicle and drivetrain configuration, CORTECO 20018100 can also be associated with an intermediate shaft.

Correct identification should be based on the OE reference together with the installation position.

The same CORTECO seal can be catalogued for different functions depending on the design of a particular engine, transmission or drivetrain.

Transmission Intermediate Shaft Seal

CORTECO 20018100 may also be found in applications involving transmission and intermediate shafts.

For transmission applications, check:

• OE reference
• transmission version
• shaft direction
• operating fluid
• installation position
• seal construction

The 35x50x7 mm dimensions alone do not confirm suitability.

Differential Shaft Seal

In certain applications, CORTECO 20018100 is also referenced as a differential shaft seal.

The exact OE reference and drivetrain configuration should be checked before installation.

CORTECO 20018100 should not be assumed to fit every differential using a nominal 35x50x7 mm seal.

CORTECO 20018100 OE Cross References

Important OE and cross-reference numbers include:

OE numbers are particularly important for this product because the same 35x50x7 mm dimensions are used by many different rotary shaft seal designs.

Toyota SU00100084 - CORTECO 20018100 - 35x50x7 mm - FPM BASLRDX7

Why is the OE Number Important?

The dimensions 35x50x7 mm are widely used for different rotary shaft seals.

Two seals can have exactly:

• 35 mm inside diameter
• 50 mm outside diameter
• 7 mm width

and still differ in:

• elastomer material
• sealing-lip construction
• dust lip
• hydrodynamic direction
• outer surface
• intended application

Dimensions are therefore only one part of correct seal identification.

How to Select a Replacement for CORTECO 20018100

Before using an alternative seal, compare:

1. CORTECO reference
2. OE/OEM reference
3. 35 mm inside diameter
4. 50 mm outside diameter
5. 7 mm width
6. FPM material
7. BASLRDX7 construction
8. additional dust lip
9. hydrodynamic direction
10. installation position and application

The most reliable identification combines:

CORTECO 20018100 + OE number + 35x50x7 mm + FPM + BASLRDX7

Technical Specification

Common Selection Mistakes

Common mistakes when selecting this seal include:

• selecting only by 35x50x7 mm dimensions
• ignoring the FPM material
• ignoring the BASLRDX7 design
• overlooking the additional dust lip
• ignoring the hydrodynamic direction
• assuming all 35x50x7 oil seals are interchangeable
• selecting only by vehicle manufacturer
• failing to verify the OE reference

For automotive applications, the exact vehicle, engine, transmission and installation position should be confirmed before fitting.
