CORTECO 19016676 ACM RHTB2 45x75x12 mm

CORTECO 19016676 ACM RHTB2 45x75x12 mm - Nissan Differential Shaft Seal

CORTECO 19016676 ACM RHTB2 45x75x12 mm is a radial rotary shaft seal for Nissan differential applications. The seal is manufactured from ACM (polyacrylate rubber) and has a nominal inside diameter of 45 mm, outside diameter of 75 mm and width of 12 mm. CORTECO identifies this specific seal construction with the RHTB2 profile.

CORTECO 19016676 - Technical Data

What Does CORTECO 19016676 ACM RHTB2 Mean?

The complete designation identifies a specific CORTECO shaft seal.

CORTECO - manufacturer and brand specialising, among other product groups, in sealing technology.

19016676 - CORTECO reference for this specific seal.

19016676B - reference also encountered in current parts catalogues and distribution channels.

82016676 - trade number associated with the product.

ACM - polyacrylate rubber used as the elastomer material.

RHTB2 - CORTECO profile designation for this specific seal construction.

45x75x12 mm - nominal seal dimensions.

CORTECO 19016676 Dimensions

The nominal dimensions are:

45x75x12 mm

where:

45 mm - nominal inside diameter / shaft diameter

75 mm - nominal outside diameter

12 mm - nominal seal width

All three dimensions must be considered when identifying a replacement.

Matching 45x75x12 mm dimensions alone do not automatically confirm complete technical interchangeability with CORTECO 19016676.

ACM - Polyacrylate Rubber

CORTECO specifies ACM as the elastomer material for reference 19016676.

ACM is polyacrylate rubber used in technical rotary shaft seals, including automotive drivetrain and transmission-related sealing applications.

The material is used in applications requiring appropriate resistance to oils and elevated operating temperatures.

However, a specific maximum operating temperature should not be assigned to CORTECO 19016676 solely from the general properties of ACM. Permissible operating conditions also depend on the exact elastomer compound, operating medium, shaft speed and design of the complete sealing system.

RHTB2 Profile

CORTECO assigns the RHTB2 profile designation to reference 19016676.

RHTB2 is therefore an important part of the complete technical identification of this product.

A replacement should not be selected solely because it has the same 45x75x12 mm dimensions.

Shaft seals with identical nominal dimensions can differ in elastomer material, sealing lip geometry, profile and operating characteristics.

The complete product identification should therefore include:

CORTECO 19016676

ACM

RHTB2

45x75x12 mm

Construction and Operating Principle

CORTECO 19016676 is a radial rotary shaft seal designed to operate between a rotating shaft and a stationary housing.

The 45 mm inside diameter corresponds to the nominal diameter of the mating shaft, while the 75 mm outside diameter corresponds to the nominal housing bore.

During operation, the sealing lip maintains controlled contact with the rotating shaft surface. Its primary purpose is to retain lubricant within the differential and limit leakage along the shaft.

The RHTB2 profile is part of the construction of this specific CORTECO seal and should be considered during product identification and replacement selection.

CORTECO 19016676 - Differential Shaft Seal

CORTECO 19016676 / 19016676B is catalogued as a differential shaft seal.

The product has confirmed applications in Nissan vehicles and is associated with differential and rear axle sealing applications in parts catalogues.

This does not mean that CORTECO 19016676 fits every Nissan vehicle.

Compatibility should be verified using the OE reference and the specific vehicle, drivetrain and differential version before installation.

NISSAN OE 3818961000

The confirmed OE reference associated with CORTECO 19016676B is:

NISSAN 3818961000

The OE number is an important reference when identifying the correct shaft seal.

If the removed component or vehicle documentation specifies 3818961000, CORTECO 19016676 / 19016676B can be identified as the corresponding aftermarket reference.

Compatibility with the exact vehicle and differential should still be confirmed before installation.

Confirmed Nissan Applications

Parts catalogues associate CORTECO 19016676B with selected versions of vehicles including:

Nissan Bluebird

Nissan Laurel

Nissan Primera

Nissan Silvia

Depending on the specific vehicle version, the seal is associated with the rear axle / differential assembly.

Exact compatibility should always be confirmed using OE reference 3818961000 and the specific vehicle data.

CORTECO 19016676 vs Other 45x75x12 mm Shaft Seals

The dimensions 45x75x12 mm alone are not sufficient to uniquely identify this shaft seal.

Different seals can have the same inside diameter, outside diameter and width while differing in:

• elastomer material,
• sealing lip construction,
• profile,
• directional characteristics,
• intended operating conditions,
• application.

For CORTECO 19016676, the relevant combination is:

45x75x12 mm

ACM

RHTB2

A generic 45x75x12 mm oil seal should therefore not automatically be considered a replacement for CORTECO 19016676.

OE Numbers and Cross-References

Confirmed OE reference:

NISSAN 3818961000

A comparison reference also encountered in parts catalogues is:

PAYEN NJ382

Cross-reference numbers are useful for product identification, but they should not be treated as independent proof of complete interchangeability without verifying the exact application.

Selection and Interchangeability

Before purchasing or replacing CORTECO 19016676, verify:

• complete CORTECO reference,
• NISSAN OE number 3818961000,
• 45 mm inside diameter,
• 75 mm outside diameter,
• 12 mm width,
• ACM material,
• RHTB2 profile,
• sealing lip construction,
• differential design,
• shaft contact surface,
• operating medium,
• operating conditions of the specific application.

Identical 45x75x12 mm dimensions do not automatically mean complete interchangeability.

The seal material and construction are as important as the basic dimensions when selecting a replacement.

Installation of CORTECO 19016676

Before installation, carefully clean the housing bore and shaft contact surface.

The shaft surface in the sealing lip contact area should be free from corrosion, sharp edges, deep scratches and other damage that could cause premature seal wear or leakage.

Install the seal evenly and without tilting, using an appropriate installation tool.

Protect the sealing lip against cutting, folding or other damage while passing the seal over the shaft.

The correct orientation of the seal relative to the lubricant side should also be confirmed before installation.
