uridan uriLOCK® – 0.3 L Blocking Fluid for Waterless Urinals

uridan uriLOCK® is the specially formulated blocking fluid used in all uridan waterless urinals to create the odour seal in the trap. It is lighter than urine, so it floats on top of the liquid in the trap, forming a stable barrier that stops sewer gases from coming back up into the bowl while still allowing each use to drain away.

This 0.3 L bottle is designed as a convenient refill size for individual fixtures. It’s ideal for cleaners and caretakers who need to top up uriLOCK® during routine servicing without carrying larger containers through the building. Simply pour the recommended dose through the trap cover to restore the seal as needed.

Used at the correct intervals, uriLOCK® keeps uridan urinals operating odour-free without any flushing water, helping facilities hit their water-saving goals while maintaining a clean, professional washroom environment.
