Duebre introduced this M3/M4 insert thread system for use with high pressure, high performance nozzles. Made out of special wear resistant steel this insert will keep the orifice dimension much longer and avoid the resulting system pressure drop. The hydrodynamic improvements have great advantages compared to sapphire inserts. Suitable for most nozzle types with M3/M4 threading.
