CORTECO 01030096B 25x37.64x6.2 HNBR BASFX12 Radial Shaft Oil Seal

CORTECO 01030096B 25x37.64x6.2 HNBR BASFX12 Radial Shaft Oil Seal

CORTECO 01030096B, base reference 01030096, is a radial shaft oil seal with exact dimensions of 25x37.64x6.2 mm. The exact CORTECO design designation is BASFX12, while current product data identify the sealing material as HNBR - Hydrogenated Nitrile Butadiene Rubber. The product is additionally identified by Trade Number 82030096 and EAN 3358960133809.

CORTECO 01030096B - Technical Specification

Manufacturer: CORTECO

Full reference: 01030096B

Base reference: 01030096

Trade Number: 82030096

Product type: Radial shaft oil seal

Design: BASFX12

Material: HNBR - Hydrogenated Nitrile Butadiene Rubber

Material code in older CORTECO catalogue data: NEM

Dimensions: 25x37.64x6.2 mm

Inside diameter d: 25 mm

Outside diameter D: 37.64 mm

Width B: 6.2 mm

EAN: 3358960133809

CORTECO 01030096B Dimensions

The exact dimensions are:

d = 25 mm - inside diameter / nominal shaft diameter

D = 37.64 mm - outside diameter

B = 6.2 mm - width

Complete dimensions:

25x37.64x6.2 mm

The decimal dimensions are particularly important for this seal.

The outside diameter should be retained as:

37.64 mm

and the width as:

6.2 mm

The product should not automatically be rounded to 25x38x6 mm, 25x38x6.2 mm or 25x38x7 mm when identifying a replacement.

A nominally similar 38 mm outside diameter does not establish dimensional interchangeability with the exact 37.64 mm specification.

BASFX12 Oil Seal Design

The exact CORTECO design designation associated with 01030096B is:

BASFX12

The complete technical identification is therefore:

CORTECO 01030096B

25x37.64x6.2 mm

HNBR

BASFX12

Trade Number 82030096

The BASFX12 designation is an important identification parameter when comparing this seal with other radial shaft seals.

A seal with similar dimensions but a different manufacturer-specific design code should not automatically be considered technically equivalent.

HNBR - Hydrogenated Nitrile Butadiene Rubber

Current product data for CORTECO 01030096B identify the sealing material as:

HNBR - Hydrogenated Nitrile Butadiene Rubber

HNBR belongs to the nitrile elastomer family but is not identical to standard NBR.

The material specification should therefore be retained when selecting a replacement.

A standard NBR seal with similar dimensions should not automatically be considered equivalent solely on the basis of size.

NEM and HNBR - Material Identification

Older CORTECO dimensional catalogue data list this reference as:

01030096 - NEM - BASFX12 - 25 - 37.64 - 6.2

Current product data identify the material as:

HNBR

For a modern English-language product description, HNBR is the clearer material designation.

The older NEM code is still useful in the technical body because it can appear in historical CORTECO catalogues and technical searches associated with reference 01030096.

CORTECO 01030096B 25x37.64x6.2 Oil Seal

The exact dimensional combination:

25x37.64x6.2 mm

is a key identification entity for this product.

The same dimensions may appear online in different decimal formats:

25x37.64x6.2

25x37,64x6,2

For an English-language product page, the recommended notation is:

25x37.64x6.2 mm

This preserves the exact catalogue dimensions while using the standard English decimal separator.

Why the 37.64 mm Outside Diameter Matters

The specified outside diameter is:

37.64 mm

not:

38 mm

The difference is:

0.36 mm

This difference should not be ignored when identifying the seal.

Radial shaft seals depend on the correct relationship between the seal outside diameter and the housing bore. Therefore, a nominal 25x38 mm seal should not automatically be considered a replacement for CORTECO 01030096B.

CORTECO 01030096B and 01030096

This product can be searched using several related identifiers:

01030096B

01030096

82030096

BASFX12

The full product reference is:

01030096B

The base reference is:

01030096

The CORTECO Trade Number is:

82030096

The exact design designation is:

BASFX12

Retaining these identifiers supports precise product identification in technical catalogues, purchasing systems and online parts searches.

CORTECO 01030096B TRW References

Catalogue data associate CORTECO 01030096B with the following TRW reference numbers:

0250080010009

0250080022009

34010925

36023059

These numbers can be useful as additional identifiers when searching historical technical documentation or cross-referencing the part.

For replacement selection, the specific application and complete seal specification should still be verified.

How to Select CORTECO 01030096B

The principal identification parameters are:

Reference - 01030096B

Dimensions - 25x37.64x6.2 mm

Material - HNBR

Design - BASFX12

Trade Number - 82030096

EAN - 3358960133809

The exact 37.64 mm outside diameter and 6.2 mm width should be retained during identification.

A rounded 38 mm outside diameter should not be substituted without technical verification.

How to Measure CORTECO 01030096B

Three principal dimensions are used for basic radial shaft seal identification:

Inside diameter d

Outside diameter D

Width B

For CORTECO 01030096B:

d = 25 mm

D = 37.64 mm

B = 6.2 mm

Because the seal uses non-integer dimensions, accurate measurement is especially important.

A used elastomeric seal may also be worn or deformed, so physical measurements should preferably be compared with the original markings and catalogue reference.

Is CORTECO 01030096B a 25x38 Oil Seal?

Not exactly.

The correct catalogue dimensions are:

25x37.64x6.2 mm

The outside diameter is therefore 37.64 mm, not 38 mm.

Although 38 mm may appear as a rounded or approximate search value, it should not replace the exact dimension in the technical specification.

HNBR vs NBR

HNBR and NBR are related nitrile-based elastomers, but they are not identical materials.

CORTECO 01030096B is identified in current product data as:

HNBR

For this reason, a standard NBR seal should not automatically be considered a technically equivalent replacement even if the dimensions appear identical.

Is Every 25x37.64x6.2 Oil Seal Interchangeable?

No.

Seals with identical dimensions can still differ in:

Sealing material

Lip construction

Outside diameter construction

Spring configuration

Directional sealing features

Operating characteristics

Manufacturer-specific design

For CORTECO 01030096B, the complete identification should include:

01030096B + 25x37.64x6.2 + HNBR + BASFX12

CORTECO 01030096B Replacement Selection

When comparing CORTECO 01030096B with another shaft seal, verify:

25x37.64x6.2 mm dimensions

HNBR sealing material

BASFX12 design

Seal construction

Operating medium

Temperature requirements

Pressure conditions

Shaft speed

Catalogue application

Operating limits from another seal should not be transferred to CORTECO 01030096B solely because the dimensions are similar.
