ELRING 850.650 Seals

ELRING 850.650 Seals

The ELRING 850.650 Seal is a high‑performance gasket designed for the intake manifold of modern gasoline and diesel engines. It offers superior sealing capability, thermal stability, and resistance to oil and fuel contaminants, ensuring reliable engine operation across a wide range of temperatures.

Key Features

• Material Composition: Made from advanced elastomer blends that maintain flexibility at low temperatures while resisting degradation at high operating temperatures.
• Temperature Range: Effective sealing from –40 °C to +200 °C, suitable for both cold climates and hot engine bays.
• Chemical Resistance: Resistant to gasoline, diesel fuel, oil, coolant, and common additives found in modern fuels.
• Dimensional Stability: Maintains its shape under pressure, preventing leaks even under high manifold pressures.
• Compatibility: Designed for a wide range of vehicle models including Peugeot, Citroën, DS, and various commercial vans and trucks that use the 850.650 intake manifold gasket specification.

Applications

The seal is used in the following engine components:

• Intake Manifold Gasket – seals the joint between the manifold and cylinder head.
• Cylinder Head Gasket – provides a barrier against coolant, oil, and fuel leaks.
• Collector Seals – ensures tight sealing of the air intake system.

It is specifically engineered for models such as:

• Peugeot Boxer 2.5 TDI (4x4)
• Citroën Jumper 2.5 L 79 kW
• DS models with the 850.650 specification
• Various commercial vans and trucks that use the same intake manifold design.

Installation Guidelines

1. Clean all mating surfaces thoroughly to remove old gasket material, oil, and debris.
2. Inspect the seal for any signs of damage or deformation before installation.
3. Place the gasket on the intake manifold with the correct orientation; most seals have a marked side indicating the direction of airflow.
4. Reassemble the cylinder head following manufacturer torque specifications to ensure even pressure distribution across the gasket.
5. After reassembly, perform a leak test at low engine speed to confirm proper sealing.

Maintenance and Longevity

The ELRING 850.650 Seal is designed for long service life under normal operating conditions. However, regular inspection during scheduled maintenance can catch early signs of wear such as cracking or hardening. Replacing the gasket at the first indication of a leak prevents engine damage and maintains optimal performance.
