WESPC U65996600 is a high-performance engine component designed for Perkins 403C series diesel engines, including models such as 403C-15 and 403C-17.​

It acts as a critical part in the engine's fuel filtration system, responsible for filtering impurities like dust, metal particles, and water from diesel fuel. This is vital for Perkins 403C series engines applied in small generator sets (10–30 kVA), compact agricultural machinery (such as small tractors and lawn mowers), and light construction equipment (like mini excavators and power trowels), protecting precision fuel injectors and pumps to ensure stable engine operation.​

U65996600 adopts high-efficiency filtration materials with a filtration precision of 5 microns, effectively removing tiny contaminants. It boasts strong pressure resistance (up to 12 bar) and high-temperature tolerance (-40°C to 120°C), maintaining stable filtration performance under harsh working conditions. Its precise size design ensures seamless fit with Perkins 403C series engines, extending the fuel system's service life and improving engine fuel efficiency.
