CORTECO 19016677 NBR TCL 19x32x7/8 mm - Toyota Steering Gear Shaft Seal

CORTECO 19016677 NBR TCL 19x32x7/8 mm is a radial rotary shaft seal for Toyota steering gear applications. The seal is manufactured from NBR (Nitrile Butadiene Rubber) and has a nominal inside diameter of 19 mm, outside diameter of 32 mm and width of 7/8 mm. CORTECO identifies this specific seal design with the TCL profile.

CORTECO 19016677 - Technical Data

What Does CORTECO 19016677 NBR TCL Mean?

The complete designation identifies a specific CORTECO sealing solution.

CORTECO - manufacturer and brand specialising, among other product groups, in automotive sealing technology.

19016677 - CORTECO reference number for this specific shaft seal.

19016677B - reference also encountered in current parts catalogues and distribution channels.

82016677 - trade number associated with this product.

NBR - Nitrile Butadiene Rubber used as the elastomer material.

TCL - CORTECO profile / design designation for this specific seal.

19x32x7/8 mm - nominal seal dimensions.

CORTECO 19016677 Dimensions

The nominal dimensions are:

19x32x7/8 mm

where:

19 mm - nominal inside diameter

32 mm - nominal outside diameter

7 mm - basic seal width

8 mm - overall width associated with the seal design

The 7/8 mm specification is technically important and should not be simplified to only 7 mm or 8 mm when identifying a replacement.

NBR - Nitrile Butadiene Rubber

CORTECO specifies NBR as the elastomer material for reference 19016677.

NBR is widely used in sealing technology because of its useful properties in contact with many mineral oils, mineral oil-based lubricants and other compatible technical fluids.

For a steering gear shaft seal, however, material compatibility must be considered together with the actual fluid and operating conditions specified for the steering system.

A precise temperature range is not assigned to this specific SKU because it has not been confirmed in the verified product data for CORTECO 19016677.

TCL Seal Design

CORTECO assigns the TCL profile designation to reference 19016677.

Catalogue data also confirms an additional dust lip.

This means the product should not be identified solely by its 19x32x7/8 mm dimensions. The TCL design and additional dust lip are important elements of the complete specification.

Another shaft seal with identical 19x32x7/8 mm dimensions may have a different lip arrangement, elastomer material or intended application and should not automatically be considered interchangeable.

Additional Dust Lip

CORTECO 19016677B is specified with an additional dust lip.

The auxiliary lip helps protect the primary sealing area against contaminants entering from the external side of the sealing point.

This feature is particularly relevant in steering gear applications, where the shaft sealing area may be exposed to dust, moisture and other external contamination.

The dust lip is therefore part of the functional construction of this specific seal rather than merely an additional dimensional feature.

CORTECO 19016677 - Steering Gear Shaft Seal

CORTECO 19016677 is catalogued as a steering gear shaft seal.

The seal operates between the shaft and the stationary housing of the steering gear. Its purpose is to retain the operating medium within the system while supporting protection of the sealing point from external contamination.

The 19 mm inside diameter corresponds to the nominal shaft diameter, while the 32 mm outside diameter corresponds to the nominal housing bore for the seal.

The exact installation conditions are determined by the steering gear design.

Toyota Application

CORTECO catalogues reference 19016677 NBR TCL 19x32x7/8 mm for Toyota applications.

Confirmed Toyota OE references associated with this seal include:

Toyota 90311-19002

Toyota 90311-19006

These OE numbers provide a more precise identification reference than the 19x32x7/8 mm dimensions alone.

Before installation in a particular vehicle, compatibility should be confirmed using the OE number, steering gear version and vehicle application data.

CORTECO 19016677 vs Other 19x32 mm Shaft Seals

The basic 19x32 mm dimensions alone are not sufficient to identify this product correctly.

Different seals may share the same inside and outside diameters while differing in:

• width,
• elastomer material,
• sealing lip profile,
• additional dust lip,
• external construction,
• intended application.

CORTECO 19016677 has a specific combination of:

19x32x7/8 mm

NBR

TCL

additional dust lip

A generic 19x32 mm oil seal should therefore not automatically be considered a replacement.

OE Numbers and Cross-References

Confirmed Toyota OE numbers:

Toyota 90311-19002

Parts catalogues also associate the following comparison references with CORTECO 19016677B:

ELRING 162.280

NOK K90311-19002

Cross-reference numbers are useful for identification but should not by themselves be treated as proof of complete interchangeability. Compatibility with the specific steering gear should be confirmed before installation.

Selection and Interchangeability

Before purchasing or replacing CORTECO 19016677, verify:

• CORTECO reference 19016677 or 19016677B,
• OE reference of the original seal,
• 19 mm inside diameter,
• 32 mm outside diameter,
• 7/8 mm width specification,
• NBR material,
• TCL profile,
• additional dust lip,
• steering gear design,
• shaft contact surface,
• operating fluid,
• requirements of the specific vehicle.

Identical basic dimensions do not automatically mean complete interchangeability.

For steering gear components, identification by CORTECO reference, Toyota OE number and complete technical specification is preferable to selection by dimensions alone.

Installation of CORTECO 19016677

Before installation, carefully clean the seal housing and the shaft contact surface.

The shaft surface in the sealing lip contact area should be free from corrosion, sharp edges, deep scratches and other damage that could cause premature seal wear or leakage.

Install the seal evenly and without tilting, using an appropriate installation tool.

Protect both the primary sealing lip and the additional dust lip against cutting, folding or other damage while passing the seal over the shaft.

The correct orientation of the seal relative to the operating fluid and external side of the steering gear should also be confirmed before installation.
