CORTECO is a brand specializing in sealing technology, including products used in automotive and industrial machinery applications.
01033971 is the manufacturer's catalogue number identifying this particular CORTECO seal.
All digits, including the leading zero, should be retained when searching for or ordering the product.
The dimensional designation identifies:
85 mm - nominal shaft diameter.
110 mm - nominal housing bore diameter.
12 mm - first axial height dimension.
17 mm - second axial height dimension associated with the seal construction.
The 12/17 designation must not be simplified to 12 mm.
Both height dimensions and the housing geometry must be considered when replacing the seal.
FPM identifies a fluoroelastomer sealing material.
The designation FKM is also commonly used internationally for this elastomer family.
Fluoroelastomers are used in industrial sealing applications requiring appropriate resistance to lubricants, temperature and selected chemicals.
B1BAVISLX26 is the complete construction profile designation.
The full profile code is important because other seals with nominal diameters of 85x110 mm may have different sealing lip arrangements or installation requirements.
Seals with B1, BA or BASL profile designations must not automatically be considered interchangeable.
FPM is a fluoroelastomer used in sealing applications where suitable resistance to lubricants, elevated temperatures and selected chemical media is required.
Typical characteristics of appropriately selected FPM compounds include:
Good resistance to many mineral oils.
Compatibility with numerous industrial greases.
Resistance to many fuels and hydrocarbons.
Potential suitability for higher operating temperatures than many standard NBR compounds.
Useful chemical resistance in selected mechanical and industrial systems.
Actual performance depends on the specific compound formulation, sealed medium, operating temperature and service conditions.
FPM should not be assumed to provide universal resistance to all chemicals.
CORTECO 01033971 belongs to the category of radial shaft seals featuring an additional dust protection lip.
In a typical construction of this type:
The primary sealing lip helps retain lubricant inside the mechanical assembly.
The additional dust lip helps restrict the entry of external dirt and contamination.
The seal body provides secure positioning within the correctly specified housing bore.
Additional dust protection is particularly relevant in mechanical systems exposed to airborne particles and environmental contamination.
However, the presence of a dust lip does not establish suitability for every heavily contaminated operating environment.
All dimensions must be considered when selecting a radial rotary shaft seal.
For CORTECO 01033971:
Nominal shaft diameter: 85 mm.
Nominal housing bore diameter: 110 mm.
Axial height dimensions: 12 mm and 17 mm.
A seal designated 85x110x12 mm is not necessarily equivalent to a seal designated 85x110x12/17 mm.
The difference may involve projecting construction elements, sealing lip positioning or required installation clearance.
Therefore, matching the two diameters alone is not sufficient to confirm interchangeability.

These products differ in profile, material or axial construction dimensions.
The comparison is intended to illustrate technical differences and does not confirm interchangeability.
CORTECO 01033971 is referenced in commercial vehicle parts catalogues, including applications associated with drivetrain and axle assemblies.
Commercial catalogue references include selected MAN and Mercedes-Benz vehicle applications.
Relevant application areas include:
Drive axle shaft sealing.

Before purchasing, verify:
CORTECO manufacturer part number 01033971.
Nominal shaft diameter of 85 mm.
Nominal housing bore diameter of 110 mm.
First axial height dimension of 12 mm.
Second axial height dimension of 17 mm.
B1BAVISLX26 construction profile.
FPM elastomer material.
Additional dust protection lip.
Type of lubricant or sealed medium.
Operating temperature and rotational speed.
Pressure and environmental conditions.
Relevant OE reference or equipment manufacturer requirements.
When in doubt, compare the original seal reference with the manufacturer's technical documentation.
Correct installation is essential for reliable sealing performance.
Before installation:
Clean the housing bore and shaft surface.
Inspect the shaft running surface for wear or damage.
Identify and correct the cause of any previous seal failure.
Verify that the available installation space accommodates the 12/17 mm construction.
Protect the sealing lips from sharp edges.
Use an appropriate seal installation tool.
Avoid tilting or distorting the seal during installation.
Apply suitable lubrication to the sealing contact area where required by the application.
Installation orientation and insertion depth must follow the design of the mechanical assembly and the equipment manufacturer's instructions.
The seal has a nominal inside diameter of 85 mm, outside diameter of 110 mm and two axial height dimensions of 12 mm and 17 mm.
The designation identifies two axial height dimensions associated with the seal construction. Both must be considered when selecting a replacement.
The specified elastomer material is FPM, a fluoroelastomer used in industrial sealing applications.
Yes. The catalogue information identifies an additional dust protection lip.
Interchangeability must not be assumed. The products differ in construction profile and axial dimensions: 85x110x12/17 mm versus 85x110x12 mm.
The part is associated with selected MAN applications in commercial catalogues. Compatibility with a particular model and mechanical assembly must be verified using the OE reference or vehicle documentation.
Not in every application. FPM may provide improved resistance to selected media and higher temperatures, but the correct material depends on the actual operating conditions.
Both designations appear in commercial catalogues and listings associated with a CORTECO seal measuring 85x110x12/17 mm. The complete supplier reference should be verified before ordering.
