CORTECO 19016642 Dimensions

The principal dimensions are:

Inside Diameter: 38 mm
Outside Diameter: 58 mm
Width / Height: 11 mm
Complete Size: 38x58x11 mm

All three dimensions are important for correct identification.

A generic 38x58x11 mm oil seal should not automatically be considered technically equivalent to CORTECO 19016642. Material, sealing design, OE reference and exact installation position should also be verified.

NBR Material

CORTECO 19016642 is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is one of the most widely used elastomers in radial shaft sealing technology and is commonly used in applications involving many mineral oils, greases and lubricants.

Material suitability depends on the operating medium, temperature, shaft speed and other working conditions.

For CORTECO 19016642, the NBR specification should therefore be considered together with the TBP design and Toyota OE reference.

TBP Seal Design

The CORTECO design designation is:

TBP

The most precise technical identification of the product is:

CORTECO 19016642 NBR TBP 38x58x11

The TBP designation is an important part of the product specification. A radial shaft seal with identical nominal dimensions but a different design should not automatically be treated as an interchangeable replacement.

Specialist catalogues describe this version as a double-lip oil seal with additional protection against contamination, but this should not be treated as an official expansion of the TBP code unless confirmed directly in CORTECO technical documentation.

Toyota OE 90311-38005

One of the principal Toyota OE references associated with CORTECO 19016642 is:

TOYOTA 90311-38005

The same reference may also be written without the hyphen:

9031138005

This number is cross-referenced with CORTECO 19016642 / 19016642B in aftermarket catalogue data.

Toyota OE 90311-38043

The second principal Toyota OE reference is:

TOYOTA 90311-38043

Alternative format:

9031138043

This OE number is also listed for CORTECO 19016642B and should be included when identifying or searching for the correct replacement.

Toyota Transmission Shaft Seal

CORTECO 19016642B is catalogued as a:

Transmission shaft seal

The product may therefore be searched as:

Toyota transmission oil seal
Toyota gearbox shaft seal
Toyota drivetrain oil seal
Toyota 90311-38005 oil seal
Toyota 90311-38043 oil seal
CORTECO 19016642 Toyota

In some aftermarket listings, the seal is also associated with the axle shaft area. However, the exact installation position should be confirmed from the Toyota OE catalogue for the specific vehicle and transmission configuration.

CORTECO 19016642 and 19016642B

The product may appear in catalogue systems under:

CORTECO 19016642
CORTECO 19016642B

The dimensional CORTECO catalogue identifies 19016642, while aftermarket and TecDoc-based catalogues frequently use 19016642B.

For inventory and ordering, the reference printed on the actual CORTECO packaging should remain the primary stock identifier.

Selected Toyota Applications

Catalogue data associate CORTECO 19016642B with selected Toyota applications, including certain versions from the:

Toyota Celica
Toyota Corolla
Toyota Hilux

Vehicle model alone should not be used as the only replacement criterion.

Different gearboxes and drivetrain configurations may have been installed within the same vehicle model range.

The preferred identification sequence is:

Toyota OE -> CORTECO reference -> dimensions -> material -> design

For this product:

90311-38005 / 90311-38043 -> CORTECO 19016642 -> 38x58x11 mm -> NBR -> TBP

Selection and Interchangeability

When selecting a replacement for CORTECO 19016642, verify:

• CORTECO reference 19016642 / 19016642B
• inside diameter 38 mm
• outside diameter 58 mm
• width 11 mm
• NBR material
• TBP design
• Toyota OE 90311-38005 or 90311-38043
• exact installation position

A generic 38x58x11 mm oil seal should not automatically be considered interchangeable with CORTECO 19016642.

This is particularly important because CORTECO catalogues include other seals with the same nominal dimensions but different materials or design codes.
