Metal-Fab, Inc. has introduced a new, totally redesigned line of special gas vent 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, precision molded to the contour of the pipe flange. At each joint, one flange has the gasket installed, the other does not. 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.

Corr/Guard® II is in full compliance with UL 1738 / CAN / ULCS636 - 1995. The flue is constructed with AL29-4C stainless steel. Choices of outside casings include aluminized steel, 430 stainless steel, 304 stainless steel, or 316 stainless steel. The new line includes a complete selection of pipe and components in 6” -24” diameter, including new 7” and 9” diameters.
