The Z-Vent III gas vent system features a snap connection pipe designed for quick, easy installation. No clamps or sealants are required, because the pipe ends contain a built-in silicone gasket. Inserting and turning the male ends results in a tight join. The Z-Vent III permits on site cutting of the pipe to required lengths. Pipe has fusion welded seams for a smoother finish and better fit.
