ELRING 019.120 Seals

ELRING 019.120 Cylinder Head Gasket

The ELRING 019.120 is a high‑performance cylinder head gasket engineered for the Mitsubishi engine family, including models such as the L200 III, DELICA, GALANT, SPACE WAGON, and PROTON variants. Designed to replace original equipment (OE) components, this gasket delivers reliable sealing under extreme operating conditions.

Core Design Features

• Composite Construction: A multi‑layer composite core consisting of a high‑temperature resistant fiber matrix bonded with a flexible metal backing. This combination ensures excellent thermal conductivity and dimensional stability.
• Precision Machining: Each gasket is machined to exact tolerances, guaranteeing a perfect fit on the cylinder head and block surfaces. The result is minimal leakage of coolant or oil.
• High‑Temperature Resistance: Capable of withstanding operating temperatures up to 400 °C (752 °F), making it suitable for both normal driving conditions and high‑performance applications.
• Corrosion Protection: The metal backing is treated to resist corrosion from coolant acids, ensuring long service life even in harsh environments.

Material Composition

The gasket’s core layers are made of a proprietary blend of carbon fiber and aramid fibers. These fibers provide exceptional strength while maintaining flexibility. The metal backing is typically a high‑strength alloy such as Aluminum 6061 or Stainless Steel 316L, depending on the specific engine variant. This dual‑material approach balances heat dissipation with mechanical durability.

Compatibility Matrix

The ELRING 019.120 is specifically calibrated for a range of Mitsubishi engines:

For each engine, the gasket dimensions are matched to the head and block geometry, ensuring a seamless seal.

Installation Guidelines

1. Preparation: Clean all mating surfaces with a solvent to remove oil, coolant residue, and old gasket material. Inspect for scratches or damage; replace any compromised components.
2. Torque Sequence: Install the head bolts in a star pattern, tightening to the manufacturer’s specified torque values (typically 80–100 Nm). Re‑torque after the first full cycle of engine operation.
3. Sealing Surface Contact: Ensure that the gasket core is fully seated against both the cylinder head and block. Avoid any gaps or misalignments.
4. Coolant Flush: After assembly, flush the cooling system with fresh coolant to eliminate trapped air pockets.

Performance Benefits

• Leak Prevention: The composite core and metal backing work together to maintain a tight seal, preventing coolant or oil leaks that could compromise engine performance.
• Thermal Efficiency: Excellent heat transfer properties help keep the combustion chamber at optimal temperatures, improving fuel efficiency and reducing wear.
• Durability: Resistant to thermal cycling and chemical attack, the gasket offers a long service life even under demanding operating conditions.
• Ease of Replacement: Designed for straightforward installation, minimizing labor time during maintenance or repair procedures.

Quality Assurance

The ELRING 019.120 undergoes rigorous testing at the manufacturer’s facilities. Each batch is evaluated for dimensional accuracy, material integrity, and sealing performance under simulated engine conditions. Compliance with international automotive standards (ISO/TS 16949) guarantees consistent quality across all units.

Environmental Considerations

The gasket’s materials are chosen to minimize environmental impact. The metal backing is recyclable, and the composite core uses fibers that can be processed in specialized recycling facilities. Additionally, by preventing leaks, the gasket helps reduce coolant loss and potential contamination of surrounding systems.

Conclusion

The ELRING 019.120 Cylinder Head Gasket represents a blend of advanced materials engineering and precise manufacturing tailored for Mitsubishi’s robust engine lineup. Its superior sealing capability, thermal performance, and durability make it an ideal choice for both routine maintenance and high‑performance applications.
