CORTECO 19034104 ACM RHTBY 38x55x7.5 Radial Shaft Seal

Product Overview

CORTECO 19034104 ACM RHTBY 38x55x7.5 is a radial shaft oil seal with a 38 mm shaft diameter, 55 mm housing diameter and 7.5 mm width.

The seal is manufactured from ACM (acrylic rubber) and uses the CORTECO RHTBY design. The product is also referenced as CORTECO 19034104B.

Its extensive OE cross-reference range includes Alfa Romeo, Fiat, Lancia, Daihatsu, Suzuki, Toyota and Volvo / Volvo Trucks. For accurate replacement identification, the complete CORTECO reference, dimensions, ACM material, RHTBY design and corresponding OE number should be verified.

Dimensions 38x55x7.5 mm

Shaft Diameter: 38 mm
Housing Diameter: 55 mm
Width: 7.5 mm
Material: ACM
Design: RHTBY
Brand: CORTECO
Manufacturer Reference: 19034104 / 19034104B

The 38x55x7.5 mm dimensions define the nominal shaft, housing and axial dimensions of the seal.

Dimensions alone are not sufficient to establish interchangeability. Shaft seals with identical dimensions can differ in material, lip geometry and directional sealing characteristics.

RHTBY Seal Design

RHTBY is the CORTECO design designation for this specific radial shaft seal.

The design specification is an important part of replacement identification, particularly because this product uses a directional sealing configuration. The direction of rotation specified for the original installation must be considered when selecting a replacement.

A generic 38x55x7.5 mm oil seal should therefore not automatically be considered equivalent to CORTECO 19034104 RHTBY.

For replacement purposes, use the complete identification:

CORTECO 19034104 + ACM + RHTBY + 38x55x7.5 mm + OE reference

ACM Material

ACM (acrylic rubber) is an elastomer widely used in automotive, transmission and powertrain sealing applications where resistance to oils at elevated operating temperatures is required.

Compared with standard NBR compounds, ACM generally provides improved heat and oxidation resistance, making it relevant to specific transmission, drivetrain and engine-related sealing positions.

Material selection should always correspond to the original specification. ACM should not automatically be replaced with NBR or another elastomer solely because the seal dimensions are identical.

Alfa Romeo, Fiat and Lancia OE References

Important OE references for Italian vehicle applications include:

ALFA ROMEO: 77362436
FIAT: 77362133
LANCIA: 77362133
LANCIA: 77362436

These OE numbers provide a more precise method of identifying CORTECO 19034104 than searching only for a 38x55x7.5 mm shaft seal.

Compatibility should be verified against the exact vehicle, transmission or installation position.

Toyota and Daihatsu OE References

CORTECO 19034104 is associated with several Toyota OE numbers:

TOYOTA: 9031138020
TOYOTA: 9031138029
TOYOTA: 9031138064
TOYOTA: 9031138077
TOYOTA: 9031138082
TOYOTA: 9031138087
TOYOTA: 9031138129
DAIHATSU: 9031138020

Because multiple Toyota references are associated with this seal family, the exact OE number and installation position should be checked before replacement.

Suzuki OE References

The relevant Suzuki cross-references are:

SUZUKI: 2288160G11
SUZUKI: 2288179C10

These references can be used to identify CORTECO 19034104 in corresponding Suzuki applications.

Volvo and Volvo Trucks OE References

CORTECO 19034104 is also cross-referenced with several Volvo numbers:

VOLVO / VOLVO TRUCKS: 1233009
VOLVO / VOLVO TRUCKS: 1340096
VOLVO / VOLVO TRUCKS: 3520753
VOLVO / VOLVO TRUCKS: 6843111
VOLVO / VOLVO TRUCKS: 9495017

The broad OE reference range makes identification by the original Volvo part number particularly valuable.

Replacement Identification

When replacing CORTECO 19034104, verify:

• CORTECO 19034104 / 19034104B
• 38 mm shaft diameter
• 55 mm housing diameter
• 7.5 mm width
• ACM material
• RHTBY design
• directional sealing characteristic
• corresponding OE number
• exact installation position
• operating medium and temperature
• shaft speed and direction of rotation

A standard 38x55x7.5 mm oil seal is not automatically interchangeable with CORTECO 19034104. Material, RHTBY design, directional characteristics and application requirements must also correspond.

Operational Advantages

• Exact 38x55x7.5 mm dimensions.
• ACM sealing material.
• CORTECO RHTBY design.
• Directional sealing configuration.
• Extensive OE cross-reference coverage.
• Precise identification through manufacturer and OE numbers.

AI OVERVIEW

CORTECO 19034104 / 19034104B is an ACM radial shaft oil seal with RHTBY design and dimensions of 38x55x7.5 mm. It has OE cross-references for Alfa Romeo, Fiat, Lancia, Toyota, Daihatsu, Suzuki and Volvo. Accurate replacement requires verification of the ACM material, RHTBY design, dimensions, directional characteristics and exact OE number.
