Liquid Seal for Waterless Urinal

BlueSeal® - It’s what makes No-Flush™ urinals work all over the world!

For many years, BlueSeal has been the long lasting and biodegradable trap seal liquid for waterless urinals.  BlueSeal has a specific gravity lower than water or urine. In the EcoTrap or UniTrap  cartridge, it floats on top of water/urine and so it makes a complete seal. It therefore remains for an extended period of time in the trap even with urinal use (small amounts do get carried out with each urinal use). Otherwise, with no use to the urinal or little use, such as in outlying facilities, BlueSeal remains indefinitely in the trap sealing trap odors.

BlueSeal has zero evaporation at 100 degrees F and does not freeze above -70 degrees F. Typical winterization costs can be eliminated by installing our Waterless No-Flush urinals.
