BlueSeal Waterless Urinal Trap Seal Liquid 1 Gallon (3.78 L) | Odor Barrier for All Waterless Urinals

• ONE GALLON, MONTHS OF SERVICE — Each refill is a single 3 oz application, so one 128 oz gallon delivers approximately 42 refills. For most facilities, one bottle keeps a urinal on schedule for months — or runs a multi-urinal restroom program between reorders.
• MADE FOR ALL WATERLESS URINALS — One liquid works across waterless / No-Flush fixtures in mixed-brand facilities: EcoTrap style and cartridge-style systems, where it reinforces the seal. For waterless urinals ONLY — not for flush urinals, sinks, or floor drains.
• FLOATS INTO PLACE, SEALS ODORS — With a specific gravity of 0.84 (per SDS), BlueSeal floats above the trap contents, forming a liquid barrier that seals sewer gases below. Ready to use straight from the jug, with zero evaporation at temperatures up to 100°F.
• THE ORIGINAL FORMULA SINCE 1991 — From Waterless Co. Inc., pioneers of the No-Flush urinal since 1991. This is the trap seal liquid engineered for the patented EcoTrap system from day one — the original from the category's inventor, not a generic relabel.
• SPECS FOR YOUR COMPLIANCE FILE — Biodegradable, septic-safe formula: near-neutral pH 6.5–7.5, VOC under 10 g/L, no California Prop 65 listed ingredients, per the published SDS (available from Waterless Co.). Light berry fragrance — an odor blocker, not an air freshener.

• Ensure the waterless urinal basin is clean and free of debris. For best results, use the product in a urinal that is already functioning as a waterless system. — Prepare the Urinal
• Carefully pour approximately 3 oz (88.7 ml) of BlueSeal Trap Seal Liquid directly into the urinal trap. The liquid's specific gravity will allow it to float and form the odor-sealing barrier. — Apply the Liquid
• Reapply the 3 oz dose every 30-60 days, or as needed based on urinal usage and environmental conditions, to maintain the liquid barrier and prevent sewer gas odors. — Maintain the Seal
