CORTECO 20033804 BAPTSFRDX7 PTFE/ACM 33x55x8.5/13.5 Differential Shaft Seal

CORTECO 20033804 BAPTSFRDX7 is a differential radial shaft seal / transmission output shaft seal measuring 33x55x8.5/13.5 mm. Current catalogue data for 20033804B identify a PTFE/ACM construction and right-hand twist. Confirmed OE references cover Dacia, Renault and Nissan applications.

CORTECO 20033804 - Characteristics

The technical identity of this specific seal can be represented as:

20033804 -> CORTECO -> BAPTSFRDX7 -> PTFE/ACM -> 33x55x8.5/13.5 mm -> differential shaft seal -> right-hand twist

Current catalogues commonly list the product as CORTECO 20033804B, while 82033804 is also associated with this reference as a trade number.

This complete identification is important because dimensions alone do not define the sealing material, lip geometry or directional characteristics.

Dimensions

The confirmed dimensions of CORTECO 20033804 / 20033804B are:

Inside Diameter: 33 mm
Outside Diameter: 55 mm
Height 1: 8.5 mm
Height 2: 13.5 mm
Complete Size: 33x55x8.5/13.5 mm

For this seal, the two axial dimensions should be retained separately as Height 1 and Height 2. The commercial size 33x55x8.5/13.5 mm should not be simplified to a conventional d x D x B designation with only one width value.

BAPTSFRDX7 Seal Design

The specific construction designation associated with CORTECO 20033804 is:

BAPTSFRDX7

This profile is part of the technical identity of the seal and should be retained when comparing it with alternative products.

A generic 33x55 mm rotary shaft seal does not necessarily reproduce the same material, sealing-lip geometry, axial dimensions or directional characteristics.

PTFE/ACM Construction

Catalogue data for CORTECO 20033804B specify the material combination as:

PTFE - polytetrafluoroethylene
ACM - polyacrylate rubber

The material configuration should be considered when selecting a replacement. A dimensionally similar elastomeric oil seal should not automatically be treated as equivalent to this PTFE/ACM design.

No specific operating-temperature range or maximum shaft speed is assigned here because these parameters have not been sufficiently confirmed for this exact CORTECO reference.

Right-Hand Twist

CORTECO 20033804B is catalogued with a right-hand twist.

The direction is a technically relevant characteristic of the sealing design. A seal with the same nominal dimensions but a different directional structure should not automatically be considered interchangeable.

For replacement selection, the direction should therefore be checked together with the BAPTSFRDX7 profile and OE reference.

Differential / Transmission Output Shaft Application

Current catalogue data classify CORTECO 20033804B as a differential shaft seal. In parts catalogues, this type of component may also be described as a transmission output shaft seal or, depending on the vehicle configuration, an axle shaft oil seal.

For precise product identification, the relationship is:

CORTECO 20033804 -> differential shaft seal -> 33x55x8.5/13.5 mm -> PTFE/ACM -> BAPTSFRDX7

The specific vehicle application should always be verified using the relevant OE reference.

Dacia OE References

Confirmed Dacia references include:

8200183825
8200621239

These OE numbers provide a more precise selection criterion than the nominal dimensions alone.

Renault OE References

Confirmed Renault references include:

8200183825
8200621239

Current cross-reference data also associate Renault 383424036R with CORTECO 20033804B.

Compatibility should still be checked for the specific gearbox, drivetrain and vehicle configuration.

Nissan OE Reference

The confirmed Nissan OE reference is:

3818900Q0A

This reference is particularly useful when identifying the seal in Nissan applications using the corresponding drivetrain components.

It does not establish compatibility with every Nissan model; the vehicle and transmission configuration should be verified.

CORTECO 20033804 vs 20033804B

The supplied base reference is 20033804, while current parts catalogues commonly identify the product as CORTECO 20033804B.

The associated trade number is:

82033804

Separate product pages for 20033804 and 20033804B should not be created solely because of the additional B unless current CORTECO documentation confirms that they are technically distinct products. This also helps avoid unnecessary SEO cannibalization.

Selection and Interchangeability

A replacement for CORTECO 20033804 / 20033804B should be selected by comparing the complete technical specification:

• inside diameter: 33 mm
• outside diameter: 55 mm
• height 1: 8.5 mm
• height 2: 13.5 mm
• BAPTSFRDX7 profile
• PTFE/ACM material configuration
• right-hand twist
• differential / transmission output shaft application
• corresponding OE reference

Identical nominal dimensions alone do not establish complete technical interchangeability.
