The CORTECO catalogue specifically lists 19027897B as 50x72x12 ACM DC, and independent TecDoc-derived data confirm the same dimensions and material.

ACM Polyacrylate Rubber

The exact material specified for CORTECO 19027897B is:

ACM - Polyacrylate Rubber.

This is an important part of the product specification.

A 50x72x12 NBR, MVQ or FKM seal should not automatically be considered equivalent simply because its installation dimensions are identical.

For a technically correct replacement, verify:

50x72x12 mm + ACM + seal design + OE/application requirements.

CORTECO DC Simmerring

The product is catalogued with the CORTECO trade references:

82027897
DC Simmerring
DC

These references are associated directly with part number 19027897B.

For English product copy, radial shaft seal is the preferred technical product term, while DC Simmerring should be retained as the manufacturer's trade/design reference.

Nissan OE 3311131G00

The principal OE reference for this CORTECO seal is:

NISSAN 3311131G00

The number is directly cross-referenced to CORTECO 19027897B / 82027897 in multiple catalogue sources.

It may also be written in formatted form as:

33111-31G00

When identifying a replacement, the OE number is more specific than searching only by the dimensions 50x72x12 mm.

Transfer Case Shaft Seal

CORTECO 19027897B is widely catalogued as:

Shaft Seal, Transfer Case.

Vehicle catalogue data associate Nissan OE 3311131G00 with selected versions of:

Nissan Pathfinder II (R50)
Nissan Patrol GR IV (Y60)
Nissan Patrol GR V (Y61)
Nissan Pick Up (D21)
Nissan Pick Up (D22)
Nissan Terrano I (WD21)
Nissan Terrano II (R20).

Compatibility should always be verified using the OE number, vehicle specification and exact installation position.

Transfer Case Seal or Oil Pump Seal?

There is an important catalogue inconsistency for this part.

Several TecDoc-based catalogues classify 19027897B as a transfer case shaft seal, while other catalogues classify the same exact part number as an oil pump shaft seal.

For this reason, the safest H1 product identification is:

Radial Shaft Seal

with transfer case included as the primary catalogue application rather than treating both application descriptions as universally interchangeable.

Nissan Applications

Catalogue data list 3311131G00 / CORTECO 19027897B for selected versions of vehicles including:

Pathfinder II R50 - including 3.3 V6 4WD
Patrol GR IV Y60 - including 2.8 TD
Patrol GR V Y61 - including 2.8 TD and 3.0 DTi
Pick Up D21 - selected 4WD versions
Pick Up D22 - selected diesel versions
Terrano I WD21 - selected 4WD versions
Terrano II R20 - including selected 2.4, 2.7 TD and 2.7 TDi versions.

Vehicle model alone should not be used as the final compatibility criterion.

Selecting CORTECO 19027897B

When identifying a replacement, verify:

• CORTECO part number 19027897B
• trade number 82027897
• Nissan OE 3311131G00
• dimensions 50x72x12 mm
• material ACM
• designation DC
• installation position
• exact vehicle and drivetrain configuration

Matching only the 50x72x12 mm dimensions does not confirm technical interchangeability.
