Elring 347.922 Seal Ring

Elring 347.922 Seal Ring

The Elring 347.922 Seal Ring is a precision-engineered component designed to provide reliable sealing for the crankshaft of high-performance vehicles, particularly those in the Porsche 911, 914, and 959 series. This part plays a critical role in maintaining engine integrity by preventing oil leakage from the crankcase while allowing smooth rotation of the crankshaft.

Key Functional Attributes

• Sealing Efficiency: Crafted from advanced elastomeric materials such as FPM (fluorinated rubber) or ACM (polyacrylate rubber), the seal ring offers exceptional resistance to oil, heat, and chemical degradation.
• Dimensional Precision: With an inner diameter of 30 mm, the ring fits snugly around the crankshaft, ensuring a tight seal without compromising rotational freedom.
• Durability: The material composition provides high wear resistance, extending service life even under aggressive operating conditions typical of sports and luxury engines.
• Compatibility: Designed to match OEM specifications for Porsche models 911, 914, and 959, the part is a direct replacement for original equipment, guaranteeing seamless integration.

Material Composition and Performance Characteristics

The Elring 347.922 Seal Ring utilizes a dual-layer construction:

1. Inner Layer (FPM): Offers superior oil resistance, maintaining elasticity at high temperatures while resisting chemical attack from engine oils and additives.
2. Outer Layer (ACM): Provides excellent abrasion resistance against metal surfaces, reducing wear on the crankshaft and surrounding components.

This combination ensures that the seal ring can withstand continuous oil flow, temperature fluctuations up to 200 °C, and mechanical stresses without compromising sealing performance.

Installation Guidelines

1. Preparation: Clean the crankshaft surface thoroughly. Remove any old gasket material or debris that could interfere with seating.
2. Alignment: Position the seal ring so that its inner diameter aligns precisely with the crankshaft bore. Avoid twisting or bending the ring during placement.
3. Seating: Gently press the ring into place, ensuring it sits flush against the crankshaft without gaps. Use a calibrated torque wrench if required to achieve optimal compression.
4. Verification: After installation, inspect for any visible oil leakage and confirm that the crankshaft rotates freely without binding.

Maintenance Tips

• Inspect the seal ring during routine engine overhauls. Look for signs of wear such as cracks, hardening, or deformation.
• Avoid exposing the part to extreme temperatures beyond its rated limits; excessive heat can accelerate material degradation.
• Use only OEM-approved lubricants and additives that are compatible with FPM/ACM elastomers to preserve sealing integrity.

Applications Across Vehicle Models

The Elring 347.922 Seal Ring is specifically engineered for:

• Porsche 911 (various generations)
• Porsche 914
• Porsche 959

Its design accommodates the unique crankshaft geometry and oil flow characteristics of these models, making it a reliable choice for both original equipment and high-performance aftermarket builds.
