The T-Cone Plug is the industry leader in reusable duct products. Containing no metal parts, the T-Cone provides a reliable seal against infiltration of debris, water and sewer gases. In blow out tests, the T-Cone has also been able to withstand 20 feet of head pressure.
The T-Cone's two-piece, threaded design, consisting of an expandable sealing gasket with a tapered poylegin-mating plug, provides for easy installation and removal. The T-Cone Plug is available in sizes ranging from 1" to 8" in diameter. Special sizes and configurations, including square gaskets are also available. T-Cone Plugs are also available with rope tie loops for tying off pull strings or ropes.
