PA ST4 DRAIN CLEANING NOZZLE – 350 BAR
Code: 2256/A


Product detailed description
The PA ST4 DRAIN CLEANING NOZZLE is a versatile and effective nozzle specifically developed for high-pressure pipe cleaning tasks in domestic and semi-professional environments. With a working pressure capacity of up to 350 bar, it is ideal for tackling grease buildup, soap residue, limescale, and small blockages.
The ST4 is equipped with a combination of rear-facing jets, which provide self-propulsion through the pipe, and a forward-facing front jet, which delivers a focused perforating action to break through tough obstructions. This dual-jet configuration ensures both smooth navigation and maximum cleaning impact.
Its rounded design allows the nozzle to move easily through tight bends and curved sections of narrow pipework, improving reach and cleaning efficiency.
Key features:
-
Max pressure: 350 bar
-
