During engine operation, it performs a critical sealing function, effectively preventing oil leakage from the front cover and blocking dust and impurities from entering the engine interior. This safeguards the cleanliness of the engine's internal environment, maintains stable oil pressure, and provides reliable lubrication conditions for the normal functioning of all engine components. For instance, in generator sets, it ensures continuous and stable power generation; in construction machinery, it assists equipment in reliably completing various operational tasks.

T400601 is manufactured from premium sealing materials, exhibiting outstanding oil resistance, heat resistance, and durability. It withstands the high temperatures (up to 150°C) and moderate pressures (approximately 100kPa) generated during prolonged engine operation, consistently maintaining excellent sealing performance. Its dimensions are precisely engineered to match the specifications of compatible engines, ensuring high accuracy and straightforward installation. It forms a tight seal against the engine's front cover, significantly reducing the risk of engine failure due to poor sealing and extending the overall service life of the engine.
