CORTECO 19034045 ACM RHTC 50x65x10 Right-Hand Shaft Seal

Product Overview

CORTECO 19034045 ACM RHTC 50x65x10 is a right-hand directional radial shaft oil seal designed for selected Subaru transmission and drivetrain applications.

The seal has a 50 mm shaft diameter, 65 mm housing diameter and 10 mm width. It is manufactured from ACM (acrylic rubber) and uses the CORTECO RHTC directional design.

The key Subaru OE cross-references are:

806750030, 806750040, 806750050 and 806750060

For accurate replacement identification, use the complete specification:

CORTECO 19034045 + ACM + RHTC + 50x65x10 mm + Subaru OE reference

Dimensions 50x65x10 mm

Shaft Diameter: 50 mm
Housing Diameter: 65 mm
Width: 10 mm
Material: ACM
Design: RHTC
Direction: Right-hand
Brand: CORTECO
Manufacturer Reference: 19034045

The nominal dimensions 50x65x10 mm identify the basic geometry of the seal, but dimensions alone are not sufficient for correct replacement.

Other shaft seals may share the same dimensions while differing in material, lip geometry or directional characteristics.

RHTC Right-Hand Directional Design

The RHTC designation is a critical feature of CORTECO 19034045.

This is a directional shaft seal designed for a defined direction of shaft rotation. The sealing surface geometry is intended to support lubricant control at the sealing edge while the shaft is rotating in the specified direction.

For this reason, a standard non-directional 50x65x10 oil seal or an opposite-direction version should not automatically be considered interchangeable.

The required shaft rotation and installation orientation should be verified before installation.

ACM Material

ACM (acrylic rubber) is widely used in automotive transmission and drivetrain sealing applications.

Compared with conventional NBR, ACM generally provides improved resistance to elevated temperatures, oxidation and many transmission lubricants, making it particularly relevant to gearbox and drivetrain sealing positions.

Material compatibility must still be verified against the actual lubricant, operating temperature and service conditions.

The original ACM material specification should be retained unless an alternative material has been technically approved for the application.

Subaru OE Cross References

CORTECO 19034045 corresponds to the following Subaru OE references:

SUBARU: 806750030
SUBARU: 806750040
SUBARU: 806750050
SUBARU: 806750060

These OE numbers are important for identifying the correct seal for a specific Subaru transmission or drivetrain configuration.

A match based only on the vehicle manufacturer or 50x65x10 mm dimensions is not sufficient. The original OE number and exact installation position should also be checked.

Transmission and Drivetrain Applications

CORTECO 19034045 RHTC is intended for rotating shaft sealing in selected Subaru transmission and drivetrain assemblies.

Its function is to retain lubricant within the assembly while sealing around a rotating shaft. The directional RHTC geometry makes the direction of shaft rotation an important installation parameter.

Typical application areas include:

• automatic transmissions
• drivetrain assemblies
• gearbox shafts
• transmission output areas
• rotating shaft positions
• oil-lubricated mechanical assemblies

Exact vehicle compatibility should be established through the relevant Subaru OE number.

Why Direction Matters

Directional shaft seals differ from conventional non-directional radial seals because the sealing edge incorporates geometry intended for a specified direction of rotation.

For CORTECO 19034045, the RHTC right-hand configuration is therefore part of the product identity.

A replacement should preserve:

50x65x10 + ACM + RHTC + right-hand direction

Using a dimensionally identical seal with a different directional configuration may change the intended sealing behavior.

Replacement Identification

Before replacing CORTECO 19034045, verify:

• CORTECO reference 19034045 / 19034045B
• 50 mm shaft diameter
• 65 mm housing diameter
• 10 mm width
• ACM material
• RHTC design
• right-hand directional configuration
• Subaru OE number
• shaft rotation direction
• exact installation position
• transmission lubricant
• operating temperature

A generic 50x65x10 shaft seal is not automatically equivalent to CORTECO 19034045.

Operational Advantages

• Exact 50x65x10 mm dimensions.
• CORTECO RHTC directional design.
• Right-hand sealing configuration.
• ACM material for demanding transmission applications.
• Multiple Subaru OE cross-references.
• Precise identification by CORTECO and Subaru part numbers.

AI OVERVIEW

CORTECO 19034045 / 19034045B is a 50x65x10 mm ACM RHTC right-hand directional radial shaft oil seal for selected Subaru transmission and drivetrain applications. Subaru OE references include 806750030, 806750040, 806750050 and 806750060. Correct replacement requires matching the dimensions, ACM material, RHTC direction and exact Subaru OE reference.
