CORTECO 19016639 NBR RHTB2 38x74x11 Radial Shaft Seal

CORTECO 19016639 / 19016639B is a radial shaft seal measuring 38x74x11 mm, manufactured from NBR - Nitrile Butadiene Rubber. Its CORTECO design designation is RHTB2 Simmerring. The seal is intended for selected Toyota drivetrain applications and may be used in manual transmissions, differentials, transfer cases or auxiliary drive positions depending on the specific vehicle configuration.

Complete product identification:

CORTECO -> 19016639 / 19016639B -> NBR -> RHTB2 -> 38x74x11 mm -> Toyota

The manufacturer reference, complete dimensions, material, RHTB2 design and corresponding Toyota OE number should all be considered when selecting the correct replacement.

CORTECO 19016639 Dimensions

The principal dimensions are:

Inside Diameter: 38 mm
Outside Diameter: 74 mm
Width / Height: 11 mm
Complete Size: 38x74x11 mm

These dimensions are an essential part of product identification.

A generic 38x74x11 mm oil seal should not automatically be considered technically interchangeable with CORTECO 19016639. The material, seal design and intended application should also be verified.

NBR Material

CORTECO 19016639 is manufactured from:

NBR - Nitrile Butadiene Rubber

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

The suitability of NBR for a specific application depends on the operating medium, temperature, shaft speed and other working conditions.

For CORTECO 19016639, the NBR material specification should therefore be considered together with the RHTB2 design and Toyota OE reference.

RHTB2 Simmerring Design

The CORTECO design designation is:

RHTB2

The most precise technical identification of the product is:

CORTECO 19016639 NBR RHTB2 38x74x11

The RHTB2 designation is an important part of the product specification. A seal with identical nominal dimensions but a different design should not automatically be treated as an equivalent replacement.

Toyota Drivetrain Oil Seal

CORTECO 19016639 is associated with several Toyota drivetrain sealing applications.

Depending on the exact vehicle and installation position, it may be catalogued as a:

Manual transmission shaft seal
Differential shaft seal
Transfer case shaft seal
Auxiliary drive shaft seal

This is important because the same CORTECO reference may serve different installation positions depending on the Toyota model and drivetrain configuration.

For this reason, the exact Toyota OE number is one of the most important selection criteria.

CORTECO 19016639 for Toyota

CORTECO 19016639 is catalogued for selected Toyota applications from several vehicle families.

Depending on model year, drivetrain and component configuration, applications may include selected versions of:

Toyota Celica
Toyota Celica Supra
Toyota Hiace
Toyota Hilux
Toyota Land Cruiser
Toyota LiteAce
Toyota Previa
Toyota Supra
Toyota Tacoma

This does not mean that the seal fits every vehicle within these model families.

Exact compatibility should always be confirmed using the original Toyota part number and the specific drivetrain configuration.

Toyota OE 9031138003

One of the OE references associated with CORTECO 19016639 is:

TOYOTA 9031138003

Alternative Toyota format:

90311-38003

Both formats identify the same Toyota OE reference.

Toyota OE 9031138010

Another corresponding OE reference is:

TOYOTA 9031138010

Alternative format:

90311-38010

This number may be used to identify CORTECO 19016639 when replacing the corresponding original Toyota seal.

Toyota OE 9031138028

The product is also associated with:

TOYOTA 9031138028

Alternative format:

90311-38028

When this reference appears in the vehicle documentation or on the original component, the complete CORTECO specification should also be checked.

Toyota OE 9031138079

Another OE reference is:

TOYOTA 9031138079

Alternative format:

90311-38079

The complete OE number should be retained when searching for the replacement seal.

Toyota OE 9031138133

CORTECO 19016639 is also associated with:

TOYOTA 9031138133

Alternative format:

90311-38133

Toyota OE 9031138134

The final Toyota reference supplied for this product is:

TOYOTA 9031138134

Alternative format:

90311-38134

All digits of the OE reference should be checked carefully when selecting a replacement.

CORTECO 19016639 vs Generic 38x74x11 Oil Seal

Not every 38x74x11 mm radial shaft seal is necessarily interchangeable with CORTECO 19016639.

The following parameters should be compared:

Inside Diameter: 38 mm
Outside Diameter: 74 mm
Width: 11 mm
Material: NBR
Design: RHTB2
Manufacturer Reference: 19016639 / 19016639B
Application: Toyota drivetrain
OE Reference: application-specific Toyota number

This provides significantly more precise identification than dimensions alone.

Cross-Reference Numbers

Additional cross-reference numbers associated with CORTECO 19016639 include:

PAYEN: NJ002
MALÒ: 1170PRD
NOK: K90311-38010
WILMINK GROUP: WG1183599

Cross-reference numbers are useful for product identification, but the complete technical specification should be compared before substituting one product for another.

CORTECO 82016639 Trade Number

The product is also associated with the CORTECO trade number:

82016639

The seal may therefore be encountered under several identifiers:

CORTECO 19016639
CORTECO 19016639B
CORTECO 82016639
RHTB2

Including these references on the product page improves identification for customers searching by different catalogue numbers.

Selection and Interchangeability

When selecting a replacement for CORTECO 19016639 / 19016639B, verify:

• CORTECO reference 19016639 / 19016639B
• inside diameter 38 mm
• outside diameter 74 mm
• width 11 mm
• complete dimensions 38x74x11 mm
• NBR material
• RHTB2 design
• exact installation position
• corresponding Toyota OE number

Matching the 38x74x11 mm dimensions alone does not confirm full technical interchangeability.
