ELRING 185.120 Seals

ELRING 185.120 Seals: Precision Engineered for Subaru Cylinder Heads

The ELRING 185.120 Seal is a high‑performance cylinder head gasket meticulously designed to meet the demanding specifications of Subaru engines, particularly the Legacy I (BC) 2.0L EJ20E/EJ20 EMPI series from 1991–1994. This component plays a critical role in maintaining engine integrity by ensuring a tight seal between the cylinder head and block, preventing coolant or oil leaks, and preserving optimal compression.

Key Technical Features

• Material Composition: Constructed from advanced metal‑soft composite material, combining a flexible metal core with high‑temperature resistant layers. This blend delivers exceptional sealing performance while accommodating thermal expansion and engine vibration.
• Design Geometry: The gasket features a precisely engineered profile that matches the cylinder head’s contour. Its shape accommodates the unique bolt pattern and head surface irregularities of Subaru’s EJ20 series, ensuring uniform pressure distribution across all mounting points.
• Temperature & Pressure Resistance: Rated to withstand operating temperatures up to 400 °C (752 °F) and internal pressures typical of a 4‑cylinder gasoline engine. This resilience guarantees long‑term reliability even under high‑performance conditions.
• Compatibility: Specifically tailored for the Subaru Legacy I, Liberty I, Impreza I, and Legacy II models equipped with the EJ20E/EJ20 EMPI 2.0L engine. The gasket’s dimensions align perfectly with these vehicles’ cylinder head designs.
• Installation Precision: Designed for exact fitment, reducing the risk of misalignment or uneven compression that could lead to leaks or reduced engine efficiency.
