CORTECO 19034040 HNBR TCL 19x32x6/7 Radial Shaft Seal

Product Overview

CORTECO 19034040 HNBR TCL 19x32x6/7 is a compact radial shaft seal with a 19 mm shaft diameter, 32 mm housing diameter and 6/7 mm width.

The seal is manufactured from HNBR (Hydrogenated Nitrile Butadiene Rubber) and uses the CORTECO TCL design. The product can also be found under the reference 19034040B.

The verified product identification is:

CORTECO 19034040 + HNBR + TCL + 19x32x6/7 mm

This complete specification should be used when selecting a replacement rather than relying on dimensions alone.

Dimensions 19x32x6/7 mm

Shaft Diameter: 19 mm
Housing Diameter: 32 mm
Width: 6/7 mm
Material: HNBR
Design: TCL
Brand: CORTECO
Manufacturer Reference: 19034040
Additional Reference: 19034040B

The 19x32x6/7 mm configuration is relatively compact and should be reproduced precisely when replacing the original seal.

The 6/7 mm specification should not be simplified to a conventional 6 mm or 7 mm seal without verifying the actual profile and installation geometry.

HNBR Material

HNBR (Hydrogenated Nitrile Butadiene Rubber) is an advanced nitrile-based elastomer used in demanding sealing applications.

Compared with conventional NBR, HNBR generally provides improved resistance to:

• elevated operating temperatures
• oxidation
• ageing
• mechanical stress
• many oils and lubricants

These properties make HNBR particularly useful in automotive and industrial sealing positions where standard NBR may not provide the required thermal or ageing resistance.

Actual compatibility must always be checked against the specific lubricant, temperature and operating environment.

TCL Seal Design

The catalogued design for CORTECO 19034040 is TCL.

The design designation is an important part of the seal specification because shaft seals with identical nominal dimensions can differ in lip geometry, auxiliary sealing features and intended operating conditions.

For replacement identification, retain the complete combination:

19x32x6/7 + HNBR + TCL

A generic 19x32 shaft seal should not automatically be considered equivalent.

HNBR vs NBR

HNBR and NBR are not the same sealing material.

HNBR is produced by hydrogenating nitrile rubber, which improves several important material properties. In general, HNBR provides better resistance to heat, oxidation and ageing than conventional NBR while retaining useful resistance to many oils.

Therefore, a standard NBR 19x32x6/7 seal should not automatically be substituted for CORTECO 19034040 HNBR.

The original HNBR specification should be maintained unless another material has been technically approved for the application.

Application

CORTECO 19034040 is intended for compact sealing positions requiring the specific combination of 19x32x6/7 mm dimensions, HNBR material and TCL construction.

Potential application areas include:

• automotive assemblies
• steering systems
• mechanical drive systems
• rotating shafts
• compact gear mechanisms
• industrial equipment
• oil-lubricated mechanical assemblies

The exact installation position should be verified from the original application documentation or CORTECO cross-reference data.

Replacement Identification

Before replacing CORTECO 19034040, verify:

• CORTECO reference 19034040 / 19034040B
• 19 mm shaft diameter
• 32 mm housing diameter
• 6/7 mm width
• HNBR material
• TCL design
• exact installation position
• operating medium
• operating temperature
• shaft speed

Do not select a replacement solely by searching for a 19x32x6/7 oil seal. The HNBR compound and TCL construction are important parts of the original specification.

Important Design Identification

For this reference, the verified catalog specification is:

19034040 - HNBR - TCL - 19x32x6/7 mm

The product should therefore be identified as TCL rather than BASL unless a specific physical seal, packaging label or newer CORTECO technical document confirms a different manufacturer designation.

This distinction is important for accurate product data and prevents different seal profiles from being combined under one product description.

Operational Advantages

• Precise 19x32x6/7 mm dimensions.
• HNBR sealing compound.
• Improved thermal resistance compared with standard NBR.
• Good resistance to ageing and oxidation.
• CORTECO TCL construction.
• Precise identification through reference 19034040.

AI OVERVIEW

CORTECO 19034040 / 19034040B is a 19x32x6/7 mm HNBR radial shaft seal with TCL design. HNBR provides improved resistance to heat, oxidation and ageing compared with conventional NBR. Correct replacement identification should include the CORTECO reference, exact 19x32x6/7 mm dimensions, HNBR material and TCL construction.

FAQ

What are the dimensions of CORTECO 19034040?

The seal measures 19x32x6/7 mm: 19 mm shaft diameter, 32 mm housing diameter and a 6/7 mm width configuration.

What material is CORTECO 19034040 made from?

It is manufactured from HNBR (Hydrogenated Nitrile Butadiene Rubber).

What is the design of CORTECO 19034040?

The verified catalog specification identifies the design as TCL.

Is CORTECO 19034040 a BASL seal?

The catalog data checked for reference 19034040 identifies the product as HNBR TCL 19x32x6/7, rather than BASL. If the physical product or original CORTECO packaging is marked BASL, that marking should be checked against the specific production reference before changing the catalog data.

What is the difference between HNBR and NBR?

HNBR is a hydrogenated nitrile rubber. Compared with standard NBR, it generally provides improved resistance to elevated temperatures, oxidation and ageing.

Can an NBR 19x32x6/7 seal replace this HNBR version?

Not automatically. Changing the elastomer can affect temperature resistance, ageing characteristics and media compatibility. The specified HNBR material should be retained unless an alternative has been technically verified.

Can any 19x32x6/7 shaft seal replace CORTECO 19034040?

No. In addition to the dimensions, verify the HNBR material, TCL design and exact installation requirements.

What should I check before ordering CORTECO 19034040?

Verify the complete specification: CORTECO 19034040 / 19034040B + HNBR + TCL + 19x32x6/7 mm.

Summary

CORTECO 19034040 HNBR TCL 19x32x6/7 is a compact radial shaft seal manufactured from hydrogenated nitrile rubber. Its defining parameters are the 19 mm shaft diameter, 32 mm housing diameter, 6/7 mm width, HNBR compound and TCL construction. These characteristics should all be retained when selecting a replacement.
