Dongfeng LoongGine Engine parts oil pan gasket 1109012-E9300

Engineered for maximum leak-proof protection, this oil pan gasket utilizes a multi-layered composite structure, combining high-quality nitrile rubber (NBR) and a reinforced metal core. The NBR layer, known for its excellent oil resistance and elasticity, conforms tightly to the uneven surfaces of the oil pan and engine block, creating a reliable seal even under thermal expansion or vibration. The metal core (typically made of galvanized steel) provides structural rigidity, preventing the gasket from deforming under torque during installation. Rigorous testing shows the gasket can withstand engine oil temperatures up to 150°C and operating pressures up to 0.3 MPa, ensuring no oil leakage even in high-load engine operation—critical for protecting engine components from oil starvation and reducing maintenance costs

The 1109012-E9300 oil pan gasket is constructed with premium materials to resist degradation from engine oil, coolant, and environmental contaminants. The NBR rubber component is formulated with anti-aging additives, preventing hardening, cracking, or swelling over time—even when exposed to long-term contact with synthetic or mineral-based engine oils. The galvanized steel core offers strong corrosion resistance, protecting against rust caused by moisture or coolant leaks that may come into contact with the gasket. Furthermore, the gasket’s surface is treated with a non-stick coating that simplifies installation and removal, reducing the risk of gasket damage during maintenance. Under normal operating conditions, the gasket delivers a service life of 80,000+ kilometers, outperforming generic gaskets and minimizing the need for frequent replacements

Designed to handle the harsh operating conditions of Dongfeng LoongGine engines, this oil pan gasket features advanced engineering to ensure thermal stability and vibration resistance. The composite material’s coefficient of thermal expansion is matched to that of the engine block and oil pan (typically aluminum or cast iron), preventing gaps from forming as the engine heats up or cools down. This thermal compatibility maintains a consistent seal across temperature fluctuations, from -40°C (cold starts) to 150°C (high-load operation). Additionally, the gasket’s flexible NBR layer absorbs engine vibration, reducing stress on the seal and preventing premature failure. The precision-machined edges of the gasket ensure uniform compression during installation, avoiding over-tightening or under-tightening issues that often lead to leaks in lower-quality gaskets

The 1109012-E9300 oil pan gasket is designed with user convenience in mind, simplifying the installation process for mechanics and maintenance teams. Its pre-cut shape and clear bolt hole markers eliminate guesswork during alignment, reducing installation time by up to 30% compared to generic gaskets. The non-stick surface coating allows for easy positioning and prevents the gasket from sticking to the engine block or oil pan during removal, reducing the risk of damage to mating surfaces. Additionally, the gasket does not require additional sealants (compatible with standard engine sealants if needed), streamlining the installation process and avoiding sealant-related issues such as clogging of oil passages. The part is also marked with the part number, material specifications, and manufacturing date for easy identification and traceability, simplifying inventory management and ensuring the correct part is used for Dongfeng LoongGine engine repairs
