BlueSeal is what makes Waterless Urinals work! BlueSeal is a long-lasting and biodegradable trap seal liquid. BlueSeal® has a specific gravity lower than water or urine. It, therefore, remains for an extended period in the trap with urinal use (small amounts do get carried out with each urinal use), or BlueSeal remains indefinitely in the trap with no use, sealing trap odors.

BlueSeal has zero evaporation at 100 degrees F and does not freeze above -70 degrees F. Commercially available cleaners will not harm the BlueSeal in the EcoTrap®.

BlueSeal is added in three (3) ounce portions into the urinal EcoTrap. Please follow the instructions on the bottle.

Note: The cleaning of Waterless urinals is affected the same way as cleaning conventional urinals. BluseSeal is available in One-gallon and 4-quart sizes.
