B-Vent Fittings

About Type B Gas Vent Pipe Fittings

Update your HVAC setup with B-vent fittings from your favorite brands like DuraVent. A common question we get is what is the difference between type B gas vent pipe fittings and double-wall stove pipe? It's confusing because B-vent employs double-wall construction, but the ends are crimped so it doesn't qualify as 100% double-wall.
