Dallas Specialty Green Drain drain trap seal
The Green Drain drain trap seal from Dallas Specialty is used to prevent sewer gases, odors and insects from entering through the floor drain grate or shower drain. The flexible gasket has sealing ribs for easy installation into a variety of drain openings. The seal opens to allow drainage and closes when there is no flow of water, and it can be used in either new construction or repair applications where there is no trap primer. Sizes are available in 2, 3, 3 1/2 and 4 inches. 800-222-5644; www.dallasspecialty.com.
