Elring 026.790 Seal Ring

Elring 026.790 Seal Ring – Precision Engineered for Crankshaft Integrity

The Elring 026.790 Seal Ring is a high‑performance crankshaft oil seal designed to provide reliable sealing at the rear of the engine block. Crafted from advanced PTFE (polytetrafluoroethylene) and FPM (fluorinated rubber) materials, this component delivers exceptional resistance to heat, pressure, and chemical exposure, ensuring long‑term durability in demanding automotive environments.

Key Design Features

• Material Composition: PTFE core for low friction and high temperature tolerance; FPM outer layer offers excellent oil compatibility and weather resistance.
• Dimensions: 85 mm diameter, 105 mm length, 8.8 mm thickness – a standard size that matches the original specifications of many modern engines.
• Sealing Surface: Precision machined to achieve a tight seal against the crankshaft journal, preventing oil leakage while allowing smooth rotation.
• Mounting Sleeve: Integrated sleeve provides secure attachment to the engine block, reducing installation time and minimizing the risk of misalignment.

Applications Across Vehicle Brands

The Elring 026.790 is engineered for a wide range of vehicles, including but not limited to:

• Audi – A5, A6, Q7, S4, Touareg, and all variants with diesel or gasoline engines.
• Citroën – Berlingo, DS4, DS5, C3 Picasso, C4 Grand Picasso, and other models equipped with 1.6 HDI or BlueHDi engines.
• Ford – Focus, Fiesta, Transit, Mondeo, and F‑Series vans featuring TDCi or TDI powertrains.
• Peugeot – 206, 307, 407, 5008, and other models with diesel engines.
• Volkswagen & Audi Group – Passat, Golf, Tiguan, Touareg, and related platforms.
• Other Manufacturers: Opel, Mazda, Mini, Fiat, Peugeot, and various PSA group vehicles.

Performance Benefits

• Oil Retention: Maintains optimal oil pressure by preventing rear crankshaft leakage, which is critical for engine lubrication and longevity.
• Thermal Stability: PTFE core withstands temperatures up to 260 °C without degradation, ensuring consistent performance under high‑load conditions.
• Chemical Resistance: FPM layer resists oil additives, fuels, and coolant contaminants, extending service life.
• Low Maintenance: Designed for a single installation cycle with minimal wear, reducing the need for frequent replacements.

Installation Overview

Installing the Elring 026.790 involves removing the old seal and aligning the new one with the crankshaft journal. The integrated mounting sleeve simplifies attachment to the engine block, ensuring a secure fit. Proper torque specifications should be followed to avoid over‑tightening, which could compromise the seal integrity.
