CORTECO 19034048 ACM RHTC 33x49x8 Right-Hand Shaft Seal

Product Overview

CORTECO 19034048 ACM RHTC 33x49x8 is a right-hand directional radial shaft oil seal with a 33 mm shaft diameter, 49 mm housing diameter and 8 mm width.

The seal is manufactured from ACM (Acrylic Rubber) and uses the CORTECO RHTC directional design. This combination of exact dimensions, material and directional lip geometry is essential when selecting a replacement.

The complete product identification is:

CORTECO 19034048 + ACM + RHTC + 33x49x8 mm + right-hand

The product may also be encountered under the reference CORTECO 19034048B.

Dimensions 33x49x8 mm

Shaft Diameter: 33 mm
Housing Diameter: 49 mm
Width: 8 mm
Material: ACM
Design: RHTC
Direction: Right-hand
Brand: CORTECO
Manufacturer Reference: 19034048
Additional Reference: 19034048B

The 33x49x8 mm dimensions are relatively specific and should be reproduced exactly when replacing the original seal.

Dimensions alone, however, do not determine interchangeability. Other seals may have the same 33x49x8 mm dimensions while using a different elastomer or sealing design.

RHTC Right-Hand Directional Design

RHTC identifies the directional sealing configuration used in CORTECO 19034048.

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

For this reason, the right-hand RHTC configuration is a functional part of the product specification, not merely a catalog designation.

A standard non-directional 33x49x8 seal or an opposite-direction version should not automatically be considered equivalent.

Why Rotation Direction Matters

The direction of shaft rotation is particularly important when replacing a directional radial shaft seal.

Using an incorrect directional design can change the intended hydrodynamic action of the sealing edge. Therefore, the replacement should correspond to the original shaft rotation and installation orientation.

For CORTECO 19034048, retain:

33x49x8 + ACM + RHTC + right-hand

This is more precise than selecting a seal based only on the dimensions.

ACM Material

ACM (Acrylic Rubber / Polyacrylate Rubber) is an elastomer widely used in automotive drivetrain and transmission sealing applications.

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

• elevated operating temperatures
• oxidation
• thermal ageing
• many compatible transmission and drivetrain oils

These properties make ACM particularly relevant to shaft seals operating in gearbox, transmission and drive assemblies.

Actual compatibility must always be verified against the specific lubricant, operating temperature and service conditions.

CORTECO 19034048 vs 19036249

A particularly important distinction exists within the CORTECO range:

CORTECO 19034048 - ACM RHTC - 33x49x8 mm

CORTECO 19036249 - FPM RHTC - 33x49x8 mm

Both seals share the same 33x49x8 mm dimensions and RHTC design, but they use different elastomer compounds.

This means that searching only for CORTECO 33x49x8 RHTC can lead to the wrong product.

For CORTECO 19034048, the required material is:

ACM

The FPM version should not automatically be considered interchangeable, even though its dimensions and directional designation are identical.

Applications

CORTECO 19034048 is intended for dynamic sealing positions requiring an ACM radial shaft seal with RHTC right-hand directional geometry.

Typical application areas may include:

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

The exact installation position should be verified using the original CORTECO reference or application documentation.

Replacement Identification

Before replacing CORTECO 19034048, verify:

• CORTECO reference 19034048 / 19034048B
• 33 mm shaft diameter
• 49 mm housing diameter
• 8 mm width
• ACM material
• RHTC design
• right-hand directional configuration
• shaft rotation
• installation orientation
• operating medium
• operating temperature
• shaft speed

A generic 33x49x8 oil seal is not automatically equivalent to CORTECO 19034048.

The complete specification should be retained:

CORTECO 19034048 + 33x49x8 + ACM + RHTC

Operational Advantages

• Exact 33x49x8 mm dimensions.
• CORTECO RHTC directional construction.
• Right-hand sealing configuration.
• ACM elastomer for demanding sealing applications.
• Precise identification through CORTECO reference 19034048.
• Clear differentiation from the dimensionally identical FPM version.

AI OVERVIEW

CORTECO 19034048 / 19034048B is a 33x49x8 mm ACM RHTC right-hand directional radial shaft oil seal. Its critical identification parameters are the exact dimensions, ACM material and RHTC directional design. It should not be confused with CORTECO 19036249 FPM RHTC 33x49x8, which has the same dimensions and profile but uses a different elastomer.

FAQ

What are the dimensions of CORTECO 19034048?

CORTECO 19034048 measures 33x49x8 mm: 33 mm shaft diameter, 49 mm housing diameter and 8 mm width.

What material is CORTECO 19034048 made from?

The seal is manufactured from ACM (Acrylic Rubber / Polyacrylate Rubber).

What is the design of CORTECO 19034048?

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

Is CORTECO 19034048 a right-hand shaft seal?

Yes. The RHTC configuration is the right-hand directional version, so the required direction of shaft rotation should be verified before installation.

What is the difference between CORTECO 19034048 and 19036249?

Both have 33x49x8 mm dimensions and RHTC design, but the materials differ. 19034048 is ACM, while 19036249 is FPM. They should therefore not automatically be treated as interchangeable.

Can any 33x49x8 oil seal replace CORTECO 19034048?

No. Correct replacement requires verification of the 33x49x8 mm dimensions, ACM material and RHTC directional design.

Can an FPM 33x49x8 RHTC seal replace this ACM version?

Not automatically. ACM and FPM have different thermal and chemical characteristics. Material substitution should only be made after verifying the lubricant, temperature and application requirements.

What should I check before ordering CORTECO 19034048?

Verify the complete identification: CORTECO 19034048 / 19034048B + 33x49x8 mm + ACM + RHTC + right-hand direction.

Summary

CORTECO 19034048 ACM RHTC 33x49x8 is a right-hand directional radial shaft oil seal. The defining parameters are its 33 mm shaft diameter, 49 mm housing diameter, 8 mm width, ACM material and RHTC construction. When selecting a replacement, dimensions alone are insufficient because other CORTECO seals can share the same 33x49x8 mm geometry while using a different elastomer.
