Elring 137.006 Seal, compressor

Product Overview

The Elring 137.006 Seal Ring for Compressor is a high‑performance sealing component designed to maintain pressure integrity in air compressors and related mechanical assemblies. It is engineered with precision to fit the crankshaft or shaft of various compressor units, ensuring reliable operation across a range of automotive and industrial applications.

Design & Construction

This seal ring features a NBR (Nitrile Butadiene Rubber) core that delivers excellent resistance to oil, fuel, and moderate temperatures. The inner diameter is precisely machined to 37 mm, providing a snug fit on the shaft while allowing for easy installation. The outer profile includes a tapered shoulder that aligns with the compressor housing, creating a tight seal against fluid leakage.

Material Properties

• NBR Elastomer: Combines flexibility and chemical resistance, suitable for environments containing lubricants and moderate temperature variations.
• High‑density core: Maintains shape under pressure, preventing extrusion or deformation during operation.
• Corrosion‑resistant metal backing (if applicable): Enhances durability in harsh operating conditions.

Compatibility & Applications

The Elring 137.006 is specifically engineered for use with compressors found in a wide array of vehicles and machinery, including but not limited to:

• BMW, MERCEDES‑BENZ, OPEL, IVECO, KHD MAGIRUS‑DEUTZ, UNIMOG, and ISETTA models.
• Air compressors, diesel engines, and other mechanical systems that require a reliable shaft seal.
• Both automotive and industrial compressor assemblies where pressure retention is critical.

Installation Guidelines

1. Preparation: Clean the shaft surface thoroughly to remove any debris or old gasket material. Ensure the diameter matches the 37 mm specification.
2. Alignment: Position the seal ring so that its tapered shoulder aligns with the compressor housing’s sealing groove.
3. Insertion: Gently slide the ring onto the shaft, allowing it to seat fully against the housing. Avoid forcing the component; use a soft mallet if necessary.
4. Verification: Inspect for proper seating and absence of gaps or misalignments before reassembling the compressor.

Performance Characteristics

The Elring 137.006 Seal Ring offers:

• Consistent pressure retention across a wide temperature range.
• Resistance to oil and fuel penetration, reducing wear on adjacent components.
• Long service life due to the robust NBR formulation and precise machining.

Maintenance & Longevity

Regular inspection of the seal ring during routine maintenance checks is recommended. Look for signs of cracking, hardening, or extrusion. Replace the component if any degradation is observed to maintain optimal compressor performance.

Technical Specifications

Conclusion

The Elring 137.006 Seal Ring for Compressor is a reliable, high‑quality component that ensures pressure integrity in critical mechanical systems. Its precise engineering, durable NBR construction, and broad compatibility make it an essential part for maintaining the performance and longevity of compressors across automotive and industrial applications.
