CORTECO 12015429B Dimensions

The principal dimensions are:

Inside diameter / nominal shaft diameter d: 87 mm

Outside diameter D: 100 mm

Width B: 8.5 mm

Complete dimensions: 87x100x8.5 mm

The first dimension corresponds to the nominal shaft diameter, the second to the outside diameter and the third to the seal width.

All three dimensions should be verified when selecting a replacement.

Matching the 87x100x8.5 mm dimensions alone does not establish complete technical interchangeability.

B1SLRS Simmerring Design

The exact CORTECO design designation for reference 12015429B is:

Design: B1SLRS Simmerring

The B1SLRS designation is an important part of the complete technical identification of this oil seal.

The construction incorporates an additional dust lip and directional sealing geometry.

The exact CORTECO design should therefore be considered together with the 87x100x8.5 mm dimensions, FPM sealing material and Left-hand Twist specification.

Another 87x100x8.5 mm oil seal should not automatically be considered constructionally equivalent.

Additional Dust Lip

CORTECO 12015429B incorporates an additional dust lip.

Additional dust lip: Yes

The dust lip provides an additional barrier on the external side of the primary sealing area and helps restrict external contaminants from reaching the main sealing interface.

The presence of the additional dust lip is an important construction characteristic when comparing CORTECO 12015429B with other 87x100x8.5 mm oil seals.

Matching dimensions alone do not confirm that another seal has the same lip configuration.

Left-hand Twist Sealing Geometry

CORTECO 12015429B is specified with directional sealing geometry.

Swirl type: Left-hand Twist

This means the seal uses left-hand directional sealing geometry.

The direction is an important construction characteristic and should be considered when selecting a corresponding replacement.

A right-hand twist seal or a seal with another directional geometry should not automatically be considered technically identical.

FPM Fluoro Rubber

The sealing material of CORTECO 12015429B is:

Material: FPM - Fluoro Rubber

FPM is a fluoroelastomer used in technical radial shaft sealing applications.

The sealing material is an important selection criterion alongside dimensions and seal construction.

An 87x100x8.5 mm oil seal manufactured from NBR, ACM or another elastomer should not automatically be considered materially equivalent to CORTECO 12015429B.

Exact material compatibility depends on the specific medium, additives, temperature and actual operating conditions.

Specific maximum temperature, pressure or shaft speed values should not be assigned to this exact product without direct confirmation for CORTECO 12015429B.

CORTECO 12015429B Crankshaft Oil Seal

CORTECO 12015429B is catalogued as a crankshaft oil seal.

Product type: Crankshaft Oil Seal

Fitting position: Transmission Side

Dimensions: 87x100x8.5 mm

Material: FPM

Design: B1SLRS Simmerring

Swirl type: Left-hand Twist

Additional dust lip: Yes

The transmission-side fitting position is an important identification criterion when selecting the correct crankshaft seal.

Compatibility with a specific vehicle and engine should be verified using the required OE reference and vehicle application data.

Why Does Left-hand Twist Matter?

Directional sealing geometry forms part of the construction of CORTECO 12015429B.

Swirl type: Left-hand Twist

For this reason, matching the 87x100x8.5 mm dimensions and FPM material alone is not sufficient to establish complete technical equivalence.

The sealing direction and exact construction should also be verified.

This is particularly important when comparing oil seals available with different directional sealing geometries.

CORTECO 12015429B vs Standard 87x100x8.5 Oil Seal

A standard radial shaft oil seal measuring 87x100x8.5 mm should not automatically be considered equivalent to CORTECO 12015429B.

CORTECO 12015429B combines:

Dimensions: 87x100x8.5 mm

Material: FPM

Design: B1SLRS Simmerring

Additional dust lip: Yes

Swirl type: Left-hand Twist

Fitting position: Transmission Side

Product type: Crankshaft Oil Seal

The complete specification should therefore be checked rather than selecting a replacement solely by dimensions.

How to Select a Replacement for CORTECO 12015429B

When selecting a corresponding oil seal, verify:

• CORTECO reference 12015429B
• dimensions 87x100x8.5 mm
• shaft diameter 87 mm
• outside diameter 100 mm
• width 8.5 mm
• sealing material FPM
• design B1SLRS Simmerring
• additional dust lip
• Left-hand Twist sealing geometry
• transmission-side fitting position
• required OE reference
• requirements of the specific vehicle and engine

Matching the 87x100x8.5 mm dimensions alone does not confirm complete technical interchangeability.
