BAVISLRSX7 Oil Seal Design

The exact CORTECO design code for reference 12014827B is:

BAVISLRSX7

This designation is more precise than describing the product simply as a generic 80x100x13 oil seal.

The complete specification combines:

80x100x13 mm geometry

FPM fluoroelastomer

additional dust lip

left-hand hydrodynamic twist

For replacement selection, the complete BAVISLRSX7 design should be considered together with the dimensions, material and OE reference.

Left-Hand Hydrodynamic Twist

CORTECO 12014827B is specified with:

Left-Hand Twist

This directional feature is part of the sealing lip geometry.

The hydrodynamic structure works in conjunction with shaft rotation and influences lubricant behaviour in the dynamic sealing zone.

For this reason, left-hand twist is a functional selection parameter, not merely an additional catalogue description.

A seal with identical 80x100x13 mm dimensions but a right-hand or different hydrodynamic structure should not automatically be considered an equivalent replacement.

Additional Dust Lip

CORTECO 12014827B incorporates an additional dust lip.

Its function is to help restrict external contaminants from reaching the primary dynamic sealing area.

When comparing alternative 80x100x13 mm oil seals, the presence of this secondary lip should therefore be checked together with the primary sealing design.

FPM Fluoroelastomer

The specified sealing material is:

FPM - Fluoroelastomer

FPM is used for radial shaft seals where resistance to oils, ageing and elevated operating temperatures is required.

Compared with standard NBR, FPM generally provides improved resistance to higher temperatures and a broader range of oils and chemical media.

Actual suitability depends on the lubricant composition, additives, temperature and operating conditions.

A specific maximum temperature, shaft speed or pressure should not be assigned without the technical specification for the exact seal and operating system.

Transmission-End Installation

The specified fitting position for CORTECO 12014827B is:

Transmission End

This information is important when identifying the seal because an engine or drivetrain assembly can use different shaft seals depending on installation position.

The product should therefore be selected using the complete combination of:

part number

dimensions

material

twist direction

fitting position

Vehicle compatibility should be confirmed using the OE reference and exact vehicle or drivetrain configuration.

CORTECO 12014827 vs 12014827B

Both references may appear in catalogues and product searches:

12014827

12014827B

The base reference is:

12014827

The complete current product reference is:

12014827B

For current product identification, CORTECO 12014827B should be used as the primary reference, while 12014827 remains useful for older catalogue searches.

Cross-References

AJUSA 15036400

FAI AutoParts OS835

PAYEN NF634

Cross-reference numbers are useful for identification, but they do not by themselves confirm that every technical characteristic is identical.

Dimensions, material, sealing design, twist direction and OE application should be verified before substitution.

Why Twist Direction Matters

CORTECO 12014827B is a directional radial shaft oil seal.

The specified direction is:

Left-Hand Twist

This characteristic should be preserved when selecting a technically corresponding replacement.

A generic 80x100x13 FPM oil seal may have the correct dimensions and elastomer while using a different sealing lip geometry.

Therefore:

80x100x13 + FPM alone is not sufficient for complete technical identification.

The more precise specification is:

80x100x13 + FPM + BAVISLRSX7 + Left-Hand Twist

How to Select CORTECO 12014827B

For correct identification, verify:

Manufacturer: CORTECO
Part Number: 12014827B
Dimensions: 80x100x13 mm
Material: FPM
Design: BAVISLRSX7
Dust Lip: Yes
Twist Direction: Left-hand
