Metal-Fab has introduced a totally redesigned line of special gas vents for condensing gas appliances, CAT II, III, and IV. Corr/Guard® II features a new design that eliminates the need for sealant at the joints. Liquid-tight connections are accomplished at each joint with the specially compounded SII Silicone Gasket. The two pieces are simply butted together and connected with a Vee band connector, engineered for exact, leak-free fit around the pipe flanges, no joint sealant required.
