Elegoo SP Neptune 4 Plus / 4 Max Hardened Steel Nozzle Kit

The Elegoo Hardened Steel Nozzle Kit is a professional-grade replacement set specifically engineered for the high-flow hotends of the Neptune 4 Plus and Neptune 4 Max. These nozzles are constructed from high-strength hardened steel to withstand abrasive filaments like carbon fiber, nylon-CF, and glow-in-the-dark PLA that would quickly degrade standard brass. With an extended heating zone and various sizes, this kit ensures stable, high-speed printing up to 500mm/s without compromising on durability or precision.
