Features

Performance Characteristics

Extreme Environment Resistance: The metal composite cylinder head gasket, designed for high compression ratios in diesel engines, can withstand high temperatures and pressures.

Superior Sealing: Rubber components (such as valve stem seals) are made of fluororubber (Viton) or high-grade nitrile rubber, offering strong anti-aging and oil resistance. Most aftermarket versions in 2025 will use asbestos-free materials.

OEM Standard: Precision down to the micron level ensures perfect alignment of all channels (water, oil, and air passages) after installation.
