General Pump Blue Rotating Turbo Nozzle - 3650 PSI, 4.0 GPM

Cut cleaning time in half with the General Pump YR36K40 Blue Rotating Turbo Nozzle — the standard commercial choice for professional pressure washing rigs operating up to 3,650 PSI at 4 GPM. This nozzle spins a zero-degree pin-stream at high velocity into a wide, cone-shaped cleaning path, delivering the raw impact of a tight stream with the broad surface coverage of a fan nozzle. The result: faster cleaning, less fatigue, and more jobs per day.

Industrial-Grade Construction

At the core is a precision wear-resistant ceramic rotor and seat assembly that maintains tight tolerances over hundreds of operational hours — far outlasting metal internals that pit and erode. The ceramic core is encased in a thick, shock-absorbing blue rubber shroud built to survive daily drops, trailer vibration, and wash bay abuse.
