Rotary Shaft Seal CORTECO 19016674 ACM RHTC9 Oil Seal 19016674

CORTECO 19016674 ACM RHTC9 40x75x12/17.5 mm - Nissan Differential Shaft Seal

CORTECO 19016674 ACM RHTC9 40x75x12/17.5 mm is a radial rotary shaft seal for Nissan differential applications. It is manufactured from ACM (polyacrylate rubber) and has a 40 mm inside diameter, 75 mm outside diameter, 12 mm basic height and 17.5 mm overall construction height. The CORTECO RHTC9 profile features a right-hand twist and an additional dust lip.

CORTECO 19016674 - Technical Data

What Does CORTECO 19016674 ACM RHTC9 Mean?

The complete designation identifies a specific CORTECO shaft seal.

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

19016674 - CORTECO reference number for this specific shaft seal.

19016674B - product reference also encountered in current catalogues and distribution channels.

82016674 - CORTECO trade number associated with this product.

ACM - polyacrylate rubber used as the elastomer material.

RHTC9 - CORTECO profile designation for this specific seal construction.

40x75x12/17.5 mm - nominal dimensions of the seal.

Catalogue data for this specific SKU also identifies a right-hand twist and an additional dust lip.

CORTECO 19016674 Dimensions

The nominal dimensions are:

40x75x12/17.5 mm

where:

40 mm - inside diameter

75 mm - outside diameter

12 mm - basic seal height

17.5 mm - second / overall construction height

The 12/17.5 mm specification is technically important. The designation should not be simplified to 40x75x12 mm because this would not describe the complete geometry of CORTECO 19016674.

ACM - Polyacrylate Rubber

CORTECO specifies ACM, or polyacrylate rubber, for reference 19016674.

ACM is an elastomer used in technical rotary shaft seals, including automotive drivetrain applications operating in contact with compatible lubricants.

The suitability of a seal must not, however, be determined solely from the general properties of ACM.

Actual operating capability depends on factors including the specific elastomer compound, lubricant or operating medium, temperature, shaft surface speed and complete sealing system design.

A specific maximum operating temperature is therefore not assigned to this SKU unless confirmed directly for CORTECO 19016674.

CORTECO RHTC9 Profile

CORTECO assigns the RHTC9 profile designation to this specific shaft seal.

Catalogue data for CORTECO 19016674 confirms:

RHTC9 profile

right-hand twist

additional dust lip

These characteristics are technically important when identifying a replacement.

A seal with dimensions 40x75x12 mm, or even 40x75x12/17.5 mm, should not automatically be considered interchangeable if it has a different profile, elastomer material or directional design.

Right-Hand Twist

CORTECO 19016674 is catalogued with a right-hand twist.

Directional characteristics are important in shaft seals where the working geometry of the sealing area is designed with a particular shaft rotation direction in mind.

For this reason, a replacement for CORTECO 19016674 should not be selected solely according to its 40 mm shaft diameter, 75 mm housing diameter and overall dimensions.

The RHTC9 profile and directional design must also be considered.

Additional Dust Lip

Catalogue data for CORTECO 19016674B confirms an additional dust lip.

The auxiliary lip helps limit the ingress of external contaminants into the primary sealing area.

This can be particularly relevant in differential applications where the sealing point may be exposed to dust, moisture, road contamination and other external particles.

The dust lip is therefore part of the functional construction of this specific CORTECO seal and should be considered when selecting a replacement.

CORTECO 19016674 - Differential Shaft Seal

CORTECO 19016674 / 19016674B is catalogued as a differential shaft seal.

The seal operates between a rotating drivetrain component and the stationary housing of the differential assembly.

Its primary sealing lip works against the shaft surface to retain lubricant inside the differential and limit leakage along the rotating shaft.

The 40 mm inside diameter corresponds to the nominal shaft diameter, while the 75 mm outside diameter corresponds to the nominal housing bore.

The exact installation geometry must match the specific differential design.

NISSAN Application

CORTECO 19016674 is catalogued for NISSAN applications.

The confirmed OE reference is:

NISSAN 38189N3100

The OE number is an important reference when identifying this seal.

Matching 38189N3100 with the vehicle documentation or the reference of the removed seal provides much more precise identification than using the 40x75x12/17.5 mm dimensions alone.

Compatibility should still be verified for the specific vehicle, axle and differential version.

Nissan Vehicle Applications

Parts catalogues associate NISSAN OE reference 38189N3100 and CORTECO 19016674B with selected versions of Nissan vehicle families including:

Nissan 280 ZX

Nissan 300 ZX

Nissan Pick Up

Nissan Primera

Nissan Sunny

Nissan Terrano

Nissan Urvan

This does not mean that the seal fits every version of the listed vehicle families.

Different drivetrain and differential configurations may have been used within the same model range. Compatibility should therefore be confirmed using OE reference 38189N3100 and the exact vehicle specification.

CORTECO 19016674 vs Other 40x75 mm Shaft Seals

The basic 40x75 mm dimensions do not uniquely identify CORTECO 19016674.

Different shaft seals can share the same inside and outside diameters while having different widths, elastomer materials, lip geometries, directional characteristics and intended applications.

This specific product combines:

40x75x12/17.5 mm

ACM

RHTC9

right-hand twist

additional dust lip

Another 40x75 mm shaft seal should therefore not automatically be considered a replacement for CORTECO 19016674.

OE Number and Cross-Reference

Confirmed OE reference:

Confirmed comparison reference:

PAYEN NJ441

Cross-reference numbers are useful when identifying a seal, but they should not be treated as independent proof of complete interchangeability.

The complete technical specification and intended application should be compared before using an alternative product.

Selection and Interchangeability

Before purchasing or replacing CORTECO 19016674 / 19016674B, verify:

• complete CORTECO reference,
• NISSAN OE reference 38189N3100,
• 40 mm inside diameter,
• 75 mm outside diameter,
• 12/17.5 mm height specification,
• ACM elastomer material,
• RHTC9 profile,
• right-hand twist,
• additional dust lip,
• differential design,
• shaft sealing surface condition,
• operating medium,
• requirements of the specific application.

Identical basic dimensions do not automatically mean complete interchangeability.

For CORTECO 19016674, the RHTC9 profile, directional design, ACM material and 12/17.5 mm construction height are particularly important identification characteristics.

Installation of CORTECO 19016674

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, burrs, deep scratches and other damage that could cause premature seal wear or leakage.

Because of the RHTC9 profile and 12/17.5 mm geometry, particular care should be taken to avoid damaging or folding the sealing lip and additional dust lip during installation.

Install the seal evenly and without tilting, using an installation tool suitable for its geometry.

Before installation, verify the correct orientation of the seal and the required operating direction associated with its right-hand twist design.
