Product description

Piston Cooling Nozzle Cummins 4937308

The original Cummins 4937308 piston cooling nozzle is a precision oil system component designed to direct an oil stream directly onto the piston crown. This ensures effective cooling and lubrication, reducing the risk of overheating, excessive wear, and engine seizure. It is used in Cummins engines as well as construction, road, and industrial machinery from brands such as Hyundai, JCB, Terex, Hitachi, and Hyster.

Description

The Cummins 4937308 nozzle is made of high-quality steel resistant to extreme temperature and pressure. Its precisely engineered geometry provides optimal oil distribution on the piston, extending engine life and increasing efficiency. This component plays a key role in maintaining stable engine operation under heavy load and long-term use.

Opinion 5/5

Zakupiony komplet siłowników do Liebherr 564 był w doskonałym stanie, zgodnie z opisem i przesłanymi zdjęciami. Obsługa na wysokim poziomie, bardzo profesjonalna i pomocna – rewelacja. Co więcej, w kontakcie z firmą otrzymałem osobistego opiekuna, który zajmował się sprawą od początku do końca, mogłem również liczyć na bezpłatne doradztwo przy montażu. Szkoda, że w obecnych czasach nie spotyka się zbyt wielu firm z tak profesjonalnym podejściem do klienta. Gorąco polecam.
