The Injector Tightening Nut is an important fastener for injectors. It locks the nozzle and seals the high-pressure fuel chamber. It is widely used on common rail injectors and mechanical injectors equipped for diesel engines of trucks, construction machinery and agricultural machinery. Forged and machined from premium alloy steel with precision turning and heat treatment, it features high strength and standard threads. It can steadily withstand high-pressure working conditions and ensure the sealing performance of assembled injectors, being a commonly used part for injector maintenance and assembly.
