BlueSeal® is the original, long-lasting biodegradable trap seal liquid engineered for Waterless No-Flush™ urinals. It helps keep fixtures odor-free, dependable, and easy to maintain.
Developed by Waterless Co. Inc.—the pioneers who introduced the No-Flush urinal in 1991—BlueSeal is specifically formulated for superior performance in the patented EcoTrap® system.
How BlueSeal® Works
Continuous Protection: During normal use, tiny amounts of BlueSeal liquid are carried away, but remaining BlueSeal instantly floats back into position to maintain the odor barrier.
Zero Evaporation: When a fixture is inactive, BlueSeal stays in place indefinitely without evaporating away like water.
Year-Round Commercial Performance
Designed to withstand demanding commercial restroom conditions, extreme seasonal temperatures, and daily custodial maintenance:
Zero Evaporation up to 100°F: Maintains an active, dependable odor barrier even in high-temperature environments.
Freeze-Resistant to -70°F: Protects fixtures in freezing temperatures, helping facilities reduce seasonal winterization labor and maintenance costs.
Cleaner Compatible: Formulated to resist degradation from standard commercial cleaning chemicals when used in the EcoTrap system.
Eco-Friendly & Safe: 100% biodegradable, septic-safe, near-neutral pH (6.5–7.5), low-VOC (<10 g/L), and contains no California Proposition 65 listed ingredients (per SDS).
Light Berry Fragrance: Neutralizes drain odors at the source rather than masking them with heavy artificial scents.
Fixture Compatibility & Installation Notes
Direct Waste-Line Connection
Waterless No-Flush urinals connect directly to a standard 2-inch (50 mm) waste line, or to a 1½-inch (38 mm) waste line when used with a reducer bushing. Because the system eliminates flush valves, water supply lines, sensors, and other moving parts, it helps reduce plumbing complexity and ongoing maintenance needs.
Universal Liquid Seal Application: BlueSeal supports waterless urinal maintenance programs across various fixture brands. It is designed for EcoTrap-style systems and cartridge-style waterless urinals to reinforce the liquid barrier.
Intended Use: For waterless urinals only. Do not use in flush urinals, sinks, or floor drains.
BlueSeal comes ready to use right out of the bottle. For EcoTrap-equipped urinals, use the PortionAid® dispenser for exact dosing:
1. Attach Dispenser: Thread the PortionAid device onto the top of the BlueSeal bottle.
2. Measure: Squeeze the bottle until the PortionAid fills to the 3 oz mark.
3. Pour: Pour the 3 oz portion directly into the openings of the EcoTrap.
4. Repeat: Repeat the process until three 3-ounce portions (9 oz total for initial fill/replenishment) are added.
5. Maintain: Follow standard custodial protocols to clean the urinal bowl, similar to conventional fixture care.
Using the PortionAid system ensures precise dosing, minimizes spills, and prevents product waste.
