SHORT DESCRIPTION

CORTECO 19016591 / 19016591B NBR TB9Y is a radial shaft seal measuring 36x64x11/19 mm for selected Mitsubishi applications. TecDoc-derived catalogue data confirm NBR material, TB9Y design, 36 mm inside diameter, 64 mm outside diameter and heights of 11 and 19 mm. The seal corresponds to Mitsubishi OE MB393807 and is catalogued for rear axle and wheel hub sealing positions, including an outer rear axle position in selected Mitsubishi 3000 GT applications.

CORTECO 19016591 NBR TB9Y 36x64x11/19 mm Shaft Seal

CORTECO 19016591 / 19016591B is a radial shaft seal measuring 36x64x11/19 mm, manufactured from NBR - Nitrile Butadiene Rubber and identified by the TB9Y design designation. The corresponding Mitsubishi OE reference is MB393807. Aftermarket catalogue data classify this seal in wheel hub and differential/rear axle sealing applications.

CORTECO 19016591 - Characteristics

Complete technical identification:

CORTECO -> 19016591 / 19016591B -> NBR -> TB9Y -> 36x64x11/19 mm -> Mitsubishi

CORTECO 19016591 Dimensions

The principal dimensions are:

Inside Diameter: 36 mm
Outside Diameter: 64 mm
Height 1: 11 mm
Height 2: 19 mm
Complete Size: 36x64x11/19 mm

TecDoc-derived data for 19016591B confirm both height values. The product should therefore not be simplified to 36x64x11 mm, because the 19 mm dimension is part of the full geometry.

A seal with the same nominal 36 mm and 64 mm diameters but a different height profile should not automatically be considered equivalent.

NBR Material

CORTECO 19016591 is manufactured from:

NBR - Nitrile Butadiene Rubber

The NBR material is confirmed in multiple catalogue listings for 19016591B.

NBR is widely used in radial shaft sealing applications involving many mineral oils, greases and lubricants.

No product-specific temperature, pressure or shaft-speed limit should be assigned to this exact CORTECO reference without manufacturer documentation for the specific variant.

TB9Y Seal Design

The confirmed CORTECO design designation is:

TB9Y

The most precise technical identification is:

CORTECO 19016591 NBR TB9Y 36x64x11/19

TecDoc-derived data also list:

82016591
TB9Y Simmerring

as associated trade references.

The TB9Y designation should be retained when comparing possible replacements. Detailed lip geometry should not be inferred solely from the code without product-specific CORTECO technical documentation.

Mitsubishi OE MB393807

The Mitsubishi OE number corresponding to CORTECO 19016591 is:

MITSUBISHI MB393807

This OE number is consistently cross-referenced to CORTECO 19016591B in aftermarket catalogues.

For replacement selection, the preferred identification sequence is:

Mitsubishi MB393807 -> CORTECO 19016591 -> 36x64x11/19 mm -> NBR -> TB9Y

Mitsubishi Wheel Hub Shaft Seal

CORTECO 19016591B is classified in TecDoc-derived catalogue data as:

Shaft Seal, wheel hub

and some catalogues additionally classify it as a:

Shaft Seal, differential.

This means the product is associated with the rear axle / wheel hub / differential sealing area, depending on the exact Mitsubishi application.

The product may therefore be searched as:

Mitsubishi wheel hub oil seal
Mitsubishi rear axle shaft seal
Mitsubishi differential shaft seal
Mitsubishi MB393807 oil seal
CORTECO 19016591 Mitsubishi

The exact installation position should always be confirmed for the specific vehicle.

Rear Axle Outer Position

For selected Mitsubishi 3000 GT applications, catalogue data specify the fitting position as:

Rear Axle, outer

This is particularly relevant because the same general axle assembly can use different inner and outer seals.

Therefore, where the vehicle catalogue specifies an outer rear axle position, this information should be checked together with Mitsubishi OE MB393807 and the full 36x64x11/19 mm dimensions.

Selected Mitsubishi Applications

Application catalogues list CORTECO 19016591B for selected:

Mitsubishi 3000 GT (Z1_A)
Mitsubishi Tredia (A21_)

For Mitsubishi 3000 GT 3.0 i 24V 4WD, the fitting position is specified as rear axle, outer. Tredia applications are also associated with the rear axle.

Vehicle model and production year alone should not be used as the sole fitment criterion. Exact compatibility should be confirmed using OE number, dimensions and installation position.

CORTECO 19016591 and 19016591B

The product may be encountered as:

CORTECO 19016591
CORTECO 19016591B

Aftermarket and TecDoc-derived sources commonly use 19016591B, with trade reference 82016591.

Both number formats are useful for search and identification, while the exact reference printed on the current packaging should be retained for ordering and warehouse purposes.

Selection and Interchangeability

When selecting a replacement for CORTECO 19016591, verify:

• CORTECO reference 19016591 / 19016591B
• inside diameter 36 mm
• outside diameter 64 mm
• height 1: 11 mm
• height 2: 19 mm
• complete size 36x64x11/19 mm
• NBR material
• TB9Y design
• Mitsubishi OE MB393807
• exact rear axle / wheel hub installation position

A generic 36x64 mm oil seal should not automatically be considered fully interchangeable with CORTECO 19016591.

The complete 11/19 mm profile, TB9Y design, OE number and installation position are important for correct replacement selection.
