Metal-Fab B-Vent 8

This category focuses on 8 inch Type B gas vent sections and fittings in the Metal-Fab B-Vent product line, organized so you can compare the details that affect fit. 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.

Look beyond the product name: confirm correct series, 8 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.
