Metal-Fab B-Vent 12

Find information and product listings for 12 inch Type B gas vent sections and fittings in the Metal-Fab B-Vent product line, with an emphasis on choosing the correct system. Type B vent is a listed gas venting system for appropriate gas-fired appliances; its double-wall construction is different from direct-vent concentric pipe.

Choosing the right item means verifying correct series, 12 inch nominal size, listed appliance application, fitting type, and mounting or termination requirements. The Metal-Fab B-Vent label identifies a particular product family. Nominal size alone does not establish compatibility with other brands or other venting designs.
