CORTECO 20029611 PTFE BAPTSLRSX7 70x86x7 Crankshaft Seal

CORTECO 20029611 / 20029611B BAPTSLRSX7 is a PTFE crankshaft seal measuring 70x86x7 mm, designed for installation on the transmission side of the crankshaft. The seal features a left-hand directional sealing structure, an additional dust lip and a mounting sleeve. Important OE references are Dacia/Renault 7701473493 and Nissan 1227900QAD.

CORTECO 20029611 - Characteristics

The technical identity of this specific product can be expressed as:

CORTECO -> 20029611 / 20029611B -> PTFE -> BAPTSLRSX7 -> 70x86x7 mm -> left-hand twist -> dust lip -> transmission side -> Dacia / Renault / Nissan

The complete specification is important because dimensions alone do not establish technical interchangeability.

A different 70x86x7 mm radial shaft seal should not automatically be considered a replacement for CORTECO 20029611.

Dimensions

The confirmed dimensions are:

Inside Diameter: 70 mm
Outside Diameter: 86 mm
Width / Height: 7 mm
Complete Size: 70x86x7 mm

All three dimensions should be checked together with the PTFE material, directional sealing structure and OE reference.

PTFE Material

CORTECO 20029611 is manufactured using PTFE - polytetrafluoroethylene sealing technology.

PTFE is commonly used in demanding crankshaft sealing applications where low friction, dimensional stability and resistance to wear are important.

However, the actual operating limits depend on the complete sealing system and application. A specific maximum temperature or shaft speed should therefore not be assigned solely from the general characteristics of PTFE.

BAPTSLRSX7 Seal Design

The product is associated with the designation:

BAPTSLRSX7

Catalogue data may also show related design/trade designations such as:

BAPTSLRSX7FT
BASLRSX7FT Simmerring
82029611

For product identification, the combination of CORTECO 20029611 / 20029611B, PTFE, 70x86x7 mm and the relevant OE references provides the most reliable basis.

Left-Hand Directional Design

CORTECO 20029611B is specified with a:

Left-hand twist sealing structure

Directionality is an important feature in crankshaft sealing applications.

A seal with the same nominal dimensions but a different directional sealing geometry should not automatically be considered technically interchangeable.

Additional Dust Lip

CORTECO 20029611B incorporates an additional dust lip.

The protective lip provides an additional barrier on the external side of the sealing area and helps restrict contamination from reaching the primary sealing interface.

The presence of this lip should be considered when comparing the seal with alternative 70x86x7 mm products.

Mounting Sleeve

The seal is supplied with a mounting sleeve.

This is particularly important for PTFE crankshaft seals, where correct installation is essential to avoid damaging or deforming the sealing lip.

The mounting sleeve should therefore be treated as part of the installation system rather than as unnecessary packaging.

Transmission-Side Crankshaft Seal

CORTECO 20029611B is catalogued as a:

Crankshaft radial shaft seal / crankshaft oil seal

Its installation position is specified as:

Transmission End / Transmission Side

This means that the seal is intended for the gearbox side of the crankshaft in its designated applications.

It should therefore not automatically be confused with a front crankshaft seal of the same or similar dimensions.

Renault and Dacia OE 7701473493

The principal OE reference for Renault and Dacia applications is:

RENAULT: 7701473493
DACIA: 7701473493

This OE number is an important identifier when searching for the correct rear/transmission-side crankshaft seal.

Some catalogues may also associate additional Renault references with this product, but compatibility should always be confirmed against the exact vehicle and engine configuration.

Nissan OE 1227900QAD

The corresponding Nissan OE reference is:

NISSAN: 1227900QAD

This reference is associated with CORTECO 20029611B and provides another precise route for product identification.

Cross-References

Important cross-references associated with this seal include:

AJUSA: 15079600
ELRING: 169.650
GLASER: P77420-01
PAYEN: NA5348
LuK: 415028610
VICTOR REINZ: 81-34462-00
BGA: OS9347

Cross-reference numbers are useful for identification, but the complete technical specification should still be compared before substitution.

Renault, Dacia and Nissan Applications

CORTECO 20029611B is catalogued for selected Renault, Dacia and Nissan applications.

Depending on engine and production version, application catalogues associate this reference with selected vehicles from families such as Renault Clio, Kangoo, Modus, Twingo, Dacia Logan and Sandero, and Nissan Kubistar.

This does not mean that the seal fits every engine or version of these models.

For accurate selection, verify:

OE number -> engine/application -> CORTECO reference -> seal specification

Selection and Interchangeability

When selecting a replacement for CORTECO 20029611 / 20029611B, verify:

• CORTECO reference 20029611 / 20029611B
• inside diameter: 70 mm
• outside diameter: 86 mm
• width: 7 mm
• PTFE material
• BAPTSLRSX7 design or corresponding CORTECO designation
• left-hand directional sealing structure
• additional dust lip
• mounting sleeve
• transmission-side installation position
• correct OE reference

Matching the 70x86x7 mm dimensions alone does not establish full technical interchangeability.

This is particularly important for directional PTFE crankshaft seals.
