Ideal for floor drains, basement drains, mop-sink drains, and other types of drains used in maintenance areas, AB&A Trap-Tite Floor Drain Trap Seal lets water flow down while keeping bad odors from drifting up. Sealing rings on the outer edges of the Trap-Tite keep the device in place for the life of the product, while the inner flaps open when liquids pour down the drain. In addition to keeping harmful and unpleasant sewer fumes out of buildings, the Trap-Tite also keeps vermin from entering and living inside of pipes. This trap seal is made of resilient polypropylene and silicone, which help mitigate trap seal loss due to evaporation. AB&A bath wastes, drains, fittings, cleanouts, and associated accessories are available in a variety of configurations and finishes to complement todayís designs and customer preferences, delivering consistent high quality in both new construction and retrofit markets.
