CORTECO 20033857 BAPTSLRDX7 PTFE/ACM 42x56x6.5 Crankshaft Oil Seal

CORTECO 20033857 BAPTSLRDX7 is a front crankshaft radial shaft seal measuring 42x56x6.5 mm. CORTECO dimensional data identify reference 20033857 as TFE - BAPTSLRDX7 CALZATO - 42x56x6.5 - CITROEN. Current catalogue data for 20033857B specify a PTFE/ACM construction, dust lip, right-hand twist and mounting sleeve.

CORTECO 20033857 - Characteristics

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

20033857 -> CORTECO -> BAPTSLRDX7 -> PTFE/ACM -> 42x56x6.5 mm -> front crankshaft oil seal -> dust lip -> right-hand twist

Current parts catalogues also list the product as CORTECO 20033857B, with trade number 82033857 and the designation BAPTSLRDX7FT Simmerring.

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

Dimensions

The confirmed dimensions of CORTECO 20033857 / 20033857B are:

Inside Diameter: 42 mm
Outside Diameter: 56 mm
Width / Height: 6.5 mm
Complete Size: 42x56x6.5 mm

The 42 mm dimension corresponds to the nominal shaft diameter, while 56 mm corresponds to the nominal housing diameter.

CORTECO also catalogues other seal configurations with the same nominal dimensions. Therefore, 42x56x6.5 mm alone is not sufficient to establish interchangeability.

BAPTSLRDX7 Seal Design

CORTECO dimensional data identify the exact reference as:

20033857 - TFE - BAPTSLRDX7 CALZATO - 42x56x6.5 - CITROEN

The BAPTSLRDX7 profile is therefore an important part of the technical identification of CORTECO 20033857.

Current catalogue data for 20033857B additionally specify:

Dust Lip: Yes
Directional Design: Right-hand twist
Mounting Sleeve: Yes

These construction characteristics should be checked together with the nominal dimensions when selecting an alternative seal.

PTFE/ACM Construction

Current catalogue data for CORTECO 20033857B identify the material combination as:

PTFE - polytetrafluoroethylene
ACM - polyacrylate rubber

CORTECO dimensional data use the material designation TFE for reference 20033857.

The material specification is relevant when comparing alternatives. Another 42x56x6.5 mm radial shaft seal manufactured with a different sealing material should not automatically be considered technically equivalent.

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

Dust Lip

CORTECO 20033857B is specified with a dust lip.

The additional lip forms a secondary barrier on the external side of the sealing system. Its presence is therefore one of the construction characteristics that should be checked when evaluating an alternative product.

A generic 42x56x6.5 mm oil seal without the corresponding lip configuration is not automatically equivalent to CORTECO 20033857.

Right-Hand Twist

The exact 20033857B reference is specified with a right-hand twist.

This directional characteristic is technically important because the sealing structure is designed in relation to shaft rotation.

A seal with identical nominal dimensions but an opposite or different directional design should not automatically be used as a replacement.

Mounting Sleeve

Current catalogue data specify CORTECO 20033857B with a mounting sleeve.

This is particularly relevant for a PTFE sealing design, where the installation procedure is important for preserving the intended geometry of the sealing lip.

The mounting sleeve should therefore be considered part of the product configuration when comparing different offers or replacement products.

Front Crankshaft Application

CORTECO 20033857B is catalogued as a crankshaft radial shaft seal with the fitting position specified as front.

The technically precise product relationship is therefore:

CORTECO 20033857 -> front crankshaft oil seal -> 42x56x6.5 mm -> PTFE/ACM -> BAPTSLRDX7

This distinction is important because the product should not be classified merely as a generic rotary shaft seal.

Citroën and Peugeot OE 0514A9

The confirmed OE reference for Citroën and Peugeot is:

Citroën: 0514A9
Peugeot: 0514A9

The reference can also be encountered in manufacturer-specific formatting as 0514.A9.

The OE number should be checked against the specific engine and vehicle configuration. Its presence does not mean that CORTECO 20033857 fits every Citroën or Peugeot vehicle.

Fiat OE 9655812480

The confirmed Fiat OE reference is:

Fiat: 9655812480

This provides a more precise identification criterion than searching only for a 42x56x6.5 crankshaft oil seal.

Compatibility with a specific vehicle should still be verified by OE number, engine version and vehicle catalogue.

CORTECO 20033857 vs 20033857B

CORTECO dimensional data list the reference as 20033857, while current parts catalogues commonly use 20033857B.

Current catalogue identification for 20033857B includes:

Trade Number: 82033857
EAN: 3358960239259
Trade Designation: BAPTSLRDX7FT Simmerring

A separate near-identical product page for 20033857B should not be created solely because of the additional B unless current CORTECO documentation confirms a technically distinct product. This helps avoid unnecessary product duplication and SEO cannibalization.

Selection and Interchangeability

A replacement for CORTECO 20033857 / 20033857B should be selected by comparing the complete technical specification:

• dimensions 42x56x6.5 mm
• PTFE/ACM material configuration
• BAPTSLRDX7 profile
• dust lip
• right-hand twist
• mounting sleeve
• front crankshaft fitting position
• Citroën/Peugeot OE 0514A9 or Fiat OE 9655812480

Identical dimensions alone do not establish complete technical interchangeability.
