CORTECO 12040000 RWDR-K7 S2 105x140x13.5/14.5 Cassette Oil Seal

CORTECO 12040000 RWDR-K7 S2 105x140x13.5/14.5 Cassette Oil Seal

CORTECO 12040000 RWDR-K7 S2 is a cassette radial shaft oil seal measuring 105x140x13.5/14.5 mm. The exact RWDR-K7 S2 construction is an essential part of the technical identification of this reference. CORTECO 12040000 is associated with MAN applications, including wheel hub sealing, and corresponds to MAN OE 81965030171. When selecting an equivalent seal, dimensional compatibility alone is insufficient. The cassette construction, complete dimensions, manufacturer reference and OE number should also be verified.

CORTECO 12040000 Dimensions

The principal dimensions of CORTECO 12040000 are:

Inside diameter d: 105 mm

Outside diameter D: 140 mm

Height 1: 13.5 mm

Height 2: 14.5 mm

Complete dimensions: 105x140x13.5/14.5 mm

The dual height specification 13.5/14.5 mm is part of the product identification and should be retained when searching for a replacement.

The dimensions should not be simplified to 105x140x14 mm.

Matching the shaft and housing diameters alone does not establish complete technical interchangeability.

RWDR-K7 S2 Oil Seal Design

The exact CORTECO design designation is:

RWDR-K7 S2

This designation identifies the specific sealing construction and should be retained when comparing technical equivalents.

Complete identification:

CORTECO reference: 12040000 / 12040000B

Trade Number: 82040000

Design: RWDR-K7 S2

Dimensions: 105x140x13.5/14.5 mm

MAN OE: 81965030171

A conventional radial shaft seal with similar nominal dimensions should not automatically be considered equivalent to an RWDR-K7 S2 cassette seal.

CORTECO 12040000 Cassette Oil Seal

CORTECO 12040000 is identified in sealing and vehicle parts catalogues as a cassette-type shaft seal.

Cassette sealing systems use a more integrated construction than a conventional single radial shaft seal and are commonly found in demanding drivetrain and wheel-end sealing positions.

For CORTECO 12040000, the most important construction identifier is:

RWDR-K7 S2

When replacing this seal, the complete construction and reference data should therefore be compared rather than relying only on the nominal 105x140 mm diameters.

CORTECO 12040000 Material

CORTECO catalogue information identifies the material for reference 12040000B as:

NBR - Nitrile Butadiene Rubber

Current TecDoc data for the same reference list:

FPM/NBR

Because the available catalogue sources differ in the way the material is specified, it is safer to retain both catalogue statements rather than assign the seal a single unverified elastomer specification.

This distinction is particularly important when evaluating temperature and media compatibility. Generic operating limits for NBR or FPM should not be transferred to this exact product without confirmation of the specific material configuration.

CORTECO 12040000 Wheel Hub Oil Seal

CORTECO 12040000 is catalogued for wheel hub / wheel-end sealing applications, including MAN vehicle applications.

Older catalogue information describes the reference as a:

CASSETTE S2 rear wheel hub seal for MAN

The cassette construction is an important consideration in a wheel hub sealing position, where the seal may have a substantially different design from a conventional radial shaft oil seal.

A standard 105x140 mm oil seal should therefore not be treated as an automatic replacement for CORTECO 12040000.

CORTECO 12040000 for MAN

CORTECO 12040000 is associated with MAN applications.

MAN OE: 81965030171

CORTECO reference: 12040000 / 12040000B

Trade Number: 82040000

Design: RWDR-K7 S2

Dimensions: 105x140x13.5/14.5 mm

Compatibility with a specific MAN vehicle should be confirmed using the OE reference and exact vehicle data.

MAN OE 81965030171

The MAN OE reference associated with CORTECO 12040000 is:

81965030171

This OE number provides an important additional identification point when searching for the correct cassette seal.

CORTECO reference: 12040000 / 12040000B

Trade Number: 82040000

MAN OE: 81965030171

Dimensions: 105x140x13.5/14.5 mm

Design: RWDR-K7 S2

When the original component carries or corresponds to MAN OE 81965030171, the CORTECO reference can be compared as a potential replacement according to the exact vehicle catalogue.

Cassette Seal for Shaft and Wheel Hub Applications

The construction of CORTECO 12040000 makes it important to distinguish this product from a conventional shaft oil seal.

The relevant identification parameters are:

Product type: Cassette oil seal

Design: RWDR-K7 S2

Inside diameter: 105 mm

Outside diameter: 140 mm

Height: 13.5/14.5 mm

CORTECO reference: 12040000 / 12040000B

MAN OE: 81965030171

The exact installation position should always be verified against the technical or vehicle parts catalogue.

Selecting an Equivalent for CORTECO 12040000

When comparing replacement seals, verify at least:

Manufacturer reference: 12040000 / 12040000B

Trade Number: 82040000

Design: RWDR-K7 S2

Inside diameter: 105 mm

Outside diameter: 140 mm

Height: 13.5/14.5 mm

MAN OE: 81965030171

Application: According to the specific vehicle or assembly catalogue

Matching 105x140x13.5/14.5 mm dimensions alone does not establish complete technical interchangeability.

In particular, a conventional radial shaft oil seal should not automatically be substituted for a cassette-type RWDR-K7 S2 seal simply because the principal dimensions are similar.
