Elring 128.210 Seal Ring

Elring 128.210 Seal Ring – Precision Engineered for Crankshaft Integrity

The Elring 128.210 Seal Ring is a high‑performance crankshaft oil seal designed to maintain optimal engine lubrication and prevent oil leakage in the rear crankshaft area. Manufactured by Elring, a leader in automotive sealing solutions, this component delivers reliable protection across a wide range of vehicle models, including BMW, Renault, Skoda, Alpine, Aro, Citroën, Dacia, De Lorean, Lancia, Nissan, Peugeot, and Volvo.

Key Features

• Material Excellence: Constructed from premium MVQ silicone rubber (silicone‑rubber blend) that offers exceptional resistance to oil, heat, and wear. The material maintains flexibility at low temperatures while retaining strength under high pressure.
• Precision Dimensions: Standard size of 80 × 100 × 13 mm ensures a perfect fit for the specified crankshaft assemblies. The ring’s inner diameter is engineered to match the oil passage, guaranteeing a tight seal without compromising shaft rotation.
• Versatile Compatibility: Designed to fit a broad spectrum of engines – from compact four‑stroke units in early BMW models (1500–2000 cc) to larger displacement powertrains in modern Skoda and Volvo vehicles. The ring’s geometry accommodates variations in crankshaft flange design.
• Durability Under Stress: The silicone rubber compound resists cracking, swelling, and oil absorption, extending service life even under aggressive operating conditions such as high RPMs or elevated engine temperatures.
• Easy Installation: The ring’s smooth profile allows for straightforward insertion into the crankshaft housing. Proper lubrication with a compatible engine oil during installation ensures minimal friction and accurate seating.

Applications Across Vehicle Families

The Elring 128.210 Seal Ring is engineered to meet the sealing demands of numerous automotive platforms:

Installation Guide

1. Preparation: Clean the crankshaft housing and oil passage thoroughly. Remove any debris or old seal remnants.
2. Lubrication: Apply a thin layer of engine oil to the inner surface of the seal ring to aid insertion and prevent damage.
3. Insertion: Align the ring with the crankshaft flange, ensuring the sealing lip faces the correct direction. Gently press the ring into place until it seats fully against the housing.
4. Verification: Rotate the crankshaft manually to confirm smooth movement and that the seal does not impede rotation. Inspect for any gaps or misalignment.
5. Final Check: After engine start, monitor oil pressure and look for leaks around the rear crankshaft area. A properly installed ring will maintain consistent oil levels without seepage.
