CORTECO 12011317 110x135x13 FPM B1VISLRS Radial Shaft Seal

CORTECO 12011317 110x135x13 FPM B1VISLRS Radial Shaft Seal

CORTECO 12011317 is a radial crankshaft seal with nominal dimensions 110x135x13 mm, manufactured from FPM fluorocarbon rubber. The exact design designation in the CORTECO dimensional catalogue is B1VISLRS. CORTECO associates this reference with IVECO, while current data for 12011317B identifies the product as a transmission-side crankshaft seal with an additional dust lip and a left-hand twist sealing structure.

The key product identification is:

CORTECO + 12011317 + 110x135x13 mm + FPM + B1VISLRS

CORTECO 12011317 – Technical Characteristics

The CORTECO dimensional catalogue directly associates 12011317 with FPM, B1VISLRS, 110x135x13 mm and IVECO.

CORTECO 12011317 Dimensions

The nominal dimensions are:

d = 110 mm – inside / shaft diameter
D = 135 mm – outside diameter
H = 13 mm – seal height

Complete dimensional designation:

110x135x13 mm

These dimensions are an essential part of product identification, but dimensions alone are not sufficient to establish interchangeability.

Another 110x135x13 mm radial shaft seal may differ in elastomer material, lip construction or directional sealing characteristics.

B1VISLRS – Exact CORTECO Profile

The CORTECO dimensional catalogue specifies the profile:

B1VISLRS

for reference 12011317.

Some current catalogue databases use the shorter designation B1SLRS for 12011317B. For this product page, I recommend retaining B1VISLRS, as this is the complete designation associated with the base reference in the CORTECO dimensional catalogue.

The individual elements of B1VISLRS should not be independently decoded unless their exact meaning for this product is supported by CORTECO technical documentation.

FPM – Fluorocarbon Rubber

CORTECO specifies the sealing material as:

FPM – fluorocarbon rubber

FPM is an elastomer used extensively in sealing technology, including radial shaft seals.

However, the available product-specific data does not establish the precise FPM compound used for CORTECO 12011317 or an individual operating-temperature range for this particular reference.

For this reason, a generic temperature range for FPM has not been assigned to this product.

When selecting a replacement, FPM should be considered together with the dimensions, seal design, directional structure and OE reference.

Additional Dust Lip

Current catalogue data for CORTECO 12011317B specifies an additional dust lip.

The primary sealing lip performs the principal sealing function around the rotating shaft, while the auxiliary lip provides an additional barrier against external contamination reaching the primary sealing area.

This constructional feature should be considered when evaluating alternatives. A seal with the same dimensions but without the corresponding auxiliary lip should not automatically be regarded as technically identical.

Left-Hand Twist Sealing Structure

CORTECO 12011317B is catalogued with:

Left-hand Twist

This describes a directional feature of the sealing structure. It should not be interpreted as a conventional mechanical thread used to screw the complete seal into its housing.

Directionality can be important when identifying a radial shaft seal. Therefore, a seal with an opposite directional design should not automatically be treated as interchangeable simply because its basic dimensions are identical.

Transmission-Side Crankshaft Seal

Current catalogue data identifies CORTECO 12011317B as a:

Shaft Seal, crankshaft – transmission sided

This means the product is catalogued as a crankshaft seal installed on the transmission side.

This is a more precise product description than the generic term “110x135x13 oil seal” and provides an additional parameter for correct identification.

The original CORTECO dimensional catalogue associates reference 12011317 with IVECO applications.

IVECO and New Holland OE References

The principal OE references associated with this CORTECO seal include:

OE references are useful for product identification, but compatibility with a specific machine or vehicle should still be verified against the exact application.

CORTECO 12011317 or 12011317B?

The CORTECO dimensional catalogue identifies the product as:

12011317

while current catalogue databases commonly use:

12011317B

For an existing product page based on 12011317, I recommend keeping the base reference in the H1 and product URL while including 12011317B prominently as an additional/current catalogue reference.

This allows the page to target searches for both designations without creating two competing product pages.

Selection and Interchangeability

When selecting a replacement for CORTECO 12011317, verify the complete product identification rather than dimensions alone.

The important parameters are 110 mm shaft diameter, 135 mm outside diameter, 13 mm height, FPM material, B1VISLRS construction, additional dust lip, left-hand twist sealing structure and the relevant OE reference.

A different 110x135x13 mm seal is therefore not automatically interchangeable with CORTECO 12011317.

Differences in elastomer material, sealing-lip geometry or directional design can be technically significant.
