DuraVent DirectVent Pro 46DVA-48B 48" Straight Pipe, 4" x 6-5/8", Black — Direct Vent Pipe

This DuraVent pipe is a 48" straight section for 4" x 6-5/8" DirectVent Pro systems, used to extend straight vent runs for gas fireplaces, stoves, and heaters. It uses fully unitized twist-lock construction for secure, tool-minimal assembly, with a black exterior and laser-welded outer wall seams. When calculating total installed length, subtract 1-1/2" per joint to account for the overlap at each connection.
