Corteco 19026231b Ring

Corteco 19026231B Ring – Precision Differential Shaft Seal

The Corteco 19026231B Ring is a high‑performance shaft seal designed specifically for the differential of Nissan vehicles, including models such as the Micra, March, and Verita. Crafted from durable materials, this ring ensures reliable sealing of gear oil while withstanding the demanding operating conditions typical of automotive differentials.

Key Technical Specifications

• Inner Diameter: 38 mm – perfectly matched to the differential housing of Nissan models.
• Outer Diameter: 58 mm – provides a secure fit within the differential casing.
• Thickness: 11 mm – offers sufficient strength and resilience against pressure fluctuations.
• Material Composition: High‑grade elastomer reinforced with carbon or steel fibers, delivering excellent resistance to oil degradation and temperature extremes.
• Seal Type: Simmerring (wellendichtring) – a double‑ring design that creates a robust barrier against fluid leakage.

Design Features & Benefits

• Dual‑Ring Construction: The outer and inner rings work in tandem to prevent oil seepage, ensuring the differential remains properly lubricated over extended periods.
• Precision Machining: Each ring is manufactured to tight tolerances, guaranteeing a snug fit that eliminates gaps and reduces wear on adjacent components.
• High‑Temperature Resistance: The elastomeric core can operate effectively up to 200 °C, making it suitable for high‑performance driving conditions.
• Corrosion & Chemical Protection: The reinforced material resists corrosion from road salts and chemical exposure, extending the seal’s service life.
• Easy Installation: Designed to replace existing seals without requiring extensive modifications or specialized tools.

Compatibility Overview

The Corteco 19026231B Ring is engineered for a range of Nissan models, including but not limited to:

• Nissan Micra (1.0 L and 1.2 L variants)
• Nissan March (I & II generations)
• Nissan Verita (II generation)
• Other Nissan models with a differential housing that matches the 38 mm inner diameter specification.

Its universal fitment within these vehicles makes it an ideal replacement for worn or damaged seals, restoring optimal performance and preventing costly fluid leaks.

Installation Guidance

1. Preparation: Remove the differential cover and clean all mating surfaces to eliminate debris and old sealant.
2. Seal Removal: Carefully extract the existing shaft seal, noting its orientation for correct placement of the new ring.
3. Installation: Align the Corteco 19026231B Ring with the differential housing, ensuring that the inner and outer rings sit flush against their respective surfaces.
4. Reassembly: Replace the cover and torque the fasteners to the manufacturer’s specifications.
5. Testing: After installation, run the vehicle at low speed to verify that no oil leaks are present.

Performance Highlights

• Maintains a tight seal under high pressure and temperature conditions.
• Reduces noise and vibration by minimizing fluid movement within the differential.
• Extends the lifespan of the differential by preventing oil loss, which can lead to premature wear.
