Injector Spring is a vital elastic component inside injectors. It controls needle valve closure via preload force and stabilizes injector opening pressure. It applies to both high-pressure common rail injectors and traditional mechanical injectors equipped on diesel engines of trucks, construction machinery, agricultural machinery and marine equipment. Manufactured from premium alloy spring steel wire with tempering strengthening treatment, it delivers balanced and lasting elastic force. It directly affects injection pressure and atomization effect, serving as a core vulnerable spare part for injector overhaul.

🔵 Made of premium alloy spring steel wire, fatigue-resistant with stable elasticity after long reciprocating operation
🔵 Standard winding process ensures uniform elastic force and steady injector opening pressure
🔵 Complete heat treatment, high temperature resistance to adapt to continuous high temperature in engine cabins
🔵 Strict dimensional accuracy and high concentricity for smooth assembly and great interchangeability with OEM parts
🔵 Complete specifications covering mainstream mechanical and common rail injectors for easy model selection
