Key Features & Technical Specifications

• Material: Fluorinated Rubber (FPM) – offers superior chemical stability, low friction, and excellent temperature tolerance up to 260 °C.
• Dimensions: Inner diameter 7 mm × Outer diameter 12 mm; stem length 24.2 mm with a flange of 18.8 mm.
• Design: Dual‑side sealing – provides both intake and exhaust side protection, reducing the risk of leakage during valve operation.
• Compatibility: Engine models from Citroën, Fiat, Ford, Jaguar, Land Rover, Mazda, Peugeot, and many others that use the 027.740 valve stem size.
• Installation: One‑piece design eliminates the need for additional gaskets or washers; it is installed directly onto the valve stem during assembly.

Performance Benefits

The Elring 027.740 Seal, Valve Stem offers a range of performance advantages that translate into improved engine efficiency and longevity:

1. Leak Prevention: The tight seal prevents oil and coolant from escaping the valve chamber, maintaining proper compression ratios.
2. Reduced Wear: Low‑friction FPM material minimizes wear on adjacent components such as camshafts and rocker arms.
3. Thermal Stability: Maintains integrity under high operating temperatures, ensuring consistent performance during engine start‑up and heavy load conditions.
4. Chemical Resistance: Resistant to oil degradation, fuel additives, and coolant chemicals, extending the seal’s service life.

Applications Across Vehicle Brands

This valve stem seal is engineered for a broad spectrum of vehicles. Below are representative examples of its use across different manufacturers:

• CITROËN: Models such as the Jumper, DS, and various engine families.
• FIAT: Including Ducato, Panda, and other commercial vehicles.
• FORD: Utilized in Mondeo III, Transit, RANGER, and many Ford powertrains.
• JAGUAR & LAND ROVER: Employed in models requiring robust valve sealing under high‑performance conditions.
• PEUGEOT & PSA GROUP: Commonly found in engines across the Peugeot, Citroën, and DS ranges.

Installation Guide

Installing the Elring 027.740 Seal, Valve Stem is straightforward for experienced technicians. Follow these steps to ensure a proper fit:

1. Preparation: Clean the valve stem thoroughly with an appropriate solvent to remove oil, dirt, and old gasket material.
2. Alignment: Position the seal onto the stem so that the flange aligns with the valve head. Ensure the inner diameter matches the stem’s bore precisely.
3. Securing: Gently press the seal into place, allowing it to conform to the stem surface without forcing or twisting.
4. Verification: Inspect for any gaps or misalignments. The seal should sit flush against both sides of the valve head.
5. Final Assembly: Proceed with the remaining engine assembly steps, ensuring that no additional pressure is applied to the seal during tightening of surrounding components.

Quality Assurance & Compliance

The Elring 027.740 Seal, Valve Stem meets stringent automotive industry standards:

• ISO 9001: Quality management system certification ensures consistent manufacturing processes.
• OEM Compatibility: Designed to match original equipment specifications for a seamless fit in new and replacement engines.
• Durability Testing: Subjected to accelerated life‑cycle tests, confirming performance under extreme temperature and pressure conditions.

Maintenance & Longevity Tips

To maximize the lifespan of your valve stem seal, consider the following maintenance practices:

• Regular Inspection: During routine engine overhauls, check for signs of wear or deformation.
• Avoid Over‑Tightening: Excessive torque on surrounding components can compress the seal beyond its design limits.
• Use Compatible Fluids: Ensure that oils and coolants are within the recommended chemical compatibility range for FPM materials.

Conclusion

The Elring 027.740 Seal, Valve Stem exemplifies precision engineering tailored to modern automotive engines. Its advanced material composition, robust design, and broad vehicle compatibility make it an essential component for maintaining engine integrity and performance.
