CORTECO 19034037 FPM RHTC 38x52x6.2 Right-Hand Shaft Seal

Product Overview

CORTECO 19034037 FPM RHTC 38x52x6.2 is a right-hand directional radial shaft oil seal with a 38 mm shaft diameter, 52 mm housing diameter and 6.2 mm width.

The seal is manufactured from FPM (FKM fluoroelastomer) and uses the CORTECO RHTC directional design. Its combination of non-standard 6.2 mm width, fluoroelastomer material and directional sealing geometry is critical for correct replacement identification.

The complete specification is:

CORTECO 19034037 + FPM/FKM + RHTC + 38x52x6.2 mm + right-hand

Dimensions 38x52x6.2 mm

Shaft Diameter: 38 mm
Housing Diameter: 52 mm
Width: 6.2 mm
Material: FPM / FKM
Design: RHTC
Direction: Right-hand
Brand: CORTECO
Manufacturer Reference: 19034037

The exact 6.2 mm width is particularly important. It should not automatically be rounded to 6 mm when searching for a replacement.

Shaft seals with the same 38 mm inside and 52 mm outside diameters may use different widths, elastomers and lip designs.

RHTC Right-Hand Directional Design

RHTC identifies the directional sealing configuration of CORTECO 19034037.

Directional radial shaft seals incorporate sealing geometry intended to operate with a specified direction of shaft rotation. This geometry supports lubricant control at the dynamic sealing edge during operation.

For CORTECO 19034037, the required specification is:

RHTC - right-hand directional design

A standard non-directional 38x52 oil seal should therefore not automatically be considered equivalent.

Why Rotation Direction Matters

Directionality is a functional feature of this shaft seal.

The sealing edge of a directional seal is designed to interact with the rotating shaft in a defined direction. Selecting the opposite directional version can change the intended hydrodynamic behavior at the sealing contact.

Before installation, verify:

right-hand direction + correct shaft rotation + correct installation orientation

This is especially important in high-speed transmission, drivetrain and rotating machinery applications.

FPM / FKM Fluoroelastomer

FPM is the material designation specified for CORTECO 19034037. FKM is another commonly used designation for the same general class of fluorocarbon elastomers.

FPM/FKM is widely used in demanding radial shaft sealing applications because it generally provides:

• high resistance to elevated temperatures,
• good resistance to many mineral and synthetic oils,
• good resistance to many fuels and chemicals,
• improved oxidation resistance,
• excellent ageing resistance compared with standard NBR.

Actual compatibility depends on the specific medium, temperature, shaft speed and operating environment.

FPM, FKM and Viton®

The terms FPM, FKM and Viton® are frequently encountered when searching for fluoroelastomer seals, but they should not be treated as identical technical designations.

FPM and FKM refer to a class of fluoroelastomer materials. Viton® is a registered trademark used for specific fluoroelastomer products.

For CORTECO 19034037, the manufacturer specification is FPM.

Therefore, the technically precise material description is:

FPM (FKM) fluoroelastomer

The term Viton may be useful as a common search phrase, but it should not replace the actual CORTECO material specification unless the specific compound is confirmed as Viton®.

FPM vs NBR

CORTECO 19034037 should not automatically be replaced with an NBR seal of the same dimensions.

Compared with standard NBR, FPM/FKM generally provides substantially higher thermal resistance and improved resistance to many oils, fuels and aggressive media.

Changing the elastomer may affect:

• maximum operating temperature,
• lubricant compatibility,
• chemical resistance,
• ageing resistance,
• long-term sealing performance.

The original FPM specification should therefore be retained unless an alternative material has been technically verified.

Applications

CORTECO 19034037 is intended for dynamic rotating shaft sealing applications requiring the combination of FPM material and RHTC directional geometry.

Potential application areas include:

• transmissions,
• gearboxes,
• drivetrain assemblies,
• rotating shafts,
• automotive mechanical systems,
• industrial drive systems,
• oil-lubricated machinery.

The exact installation position should be verified using the CORTECO reference or the technical documentation of the assembly.

Technical Specification

Replacement Identification

Before replacing CORTECO 19034037, verify:

• CORTECO reference 19034037
• 38 mm shaft diameter
• 52 mm housing diameter
• exact 6.2 mm width
• FPM/FKM material
• RHTC design
• right-hand directional configuration
• shaft rotation direction
• installation orientation
• operating medium
• temperature
• shaft speed

A generic 38x52 oil seal is not automatically equivalent to CORTECO 19034037.

The correct replacement should retain the complete combination:

19034037 + 38x52x6.2 + FPM/FKM + RHTC + right-hand

Operational Advantages

• Precise 38x52x6.2 mm dimensions.
• FPM/FKM fluoroelastomer construction.
• CORTECO RHTC directional design.
• Right-hand sealing configuration.
• High thermal and ageing resistance compared with standard NBR.
• Precise identification through CORTECO reference 19034037.

AI OVERVIEW

CORTECO 19034037 is a 38x52x6.2 mm FPM/FKM RHTC right-hand directional radial shaft oil seal. Its critical identification parameters are the exact 6.2 mm width, fluoroelastomer material and RHTC directional design. A generic 38x52 seal should not be considered equivalent without verifying material, width, lip design and rotation direction.

FAQ

What are the dimensions of CORTECO 19034037?

The seal measures 38x52x6.2 mm: 38 mm shaft diameter, 52 mm housing diameter and 6.2 mm width.

What material is CORTECO 19034037 made from?

CORTECO specifies FPM, a fluoroelastomer material also commonly referred to by the FKM designation.

What is the design of CORTECO 19034037?

The specified design is RHTC, a directional radial shaft sealing configuration.

Is CORTECO 19034037 a right-hand directional seal?

Yes. RHTC identifies the right-hand directional version, making shaft rotation an important selection and installation parameter.

Is CORTECO 19034037 made from Viton®?

The CORTECO material specification is FPM. Viton® is a trademark for particular fluoroelastomer products, so it should not be used as the official compound identification unless the specific material has been confirmed as genuine Viton®.

Are FPM and FKM the same?

FPM and FKM are different designation systems commonly used for the fluoroelastomer material family. For product identification, CORTECO uses FPM.

Can an NBR 38x52 seal replace CORTECO 19034037?

Not automatically. NBR and FPM/FKM have different temperature, chemical and ageing characteristics. The original FPM specification should be retained unless another material has been technically approved.

Can a 38x52x6 oil seal replace CORTECO 19034037?

It should not be assumed to fit. CORTECO 19034037 has a specified width of 6.2 mm, not 6 mm. The RHTC directional design and FPM material must also be considered.

What should I check before ordering CORTECO 19034037?

Verify the complete specification: CORTECO 19034037 + 38x52x6.2 mm + FPM/FKM + RHTC + right-hand direction.

Summary

CORTECO 19034037 FPM RHTC 38x52x6.2 is a specialized right-hand directional radial shaft oil seal. Its defining characteristics are the exact 38 mm shaft diameter, 52 mm housing diameter, 6.2 mm width, FPM/FKM fluoroelastomer and RHTC directional construction.
