Description

The NPR piston rings with part number 8914500000 are high-quality components designed for combustion engines used in Liebherr construction machinery. Their function is to seal the combustion chamber, reduce gas blow-by, and transfer heat from the piston to the cylinder liner. Thanks to precise machining and the use of advanced materials, the rings are durable and resistant to extreme working conditions, including high pressures and temperatures. Manufactured according to NPR standards, they guarantee reliable performance and long service life.

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.
