DuraVent is the premier company in the venting industry. With a broad range of engineered venting products, DuraVent has earned its reputation as the industry leader by offering innovative, safe, and professional products for the HVAC and Hearth markets.
Type B Gas Vent DuraVent's innovative system for a lock-tight connection for Type B Gas Vent is called DuraLock. See the alignment indicators meet; feel the ends grasp together; hear the snap as the connection firmly locks into place.
Strong, durable galvanized steel outer pipe has internal spacing beads to assure a uniform insulating air space between pipe walls. Each end is die-formed to assure uniform sizing for strong, easy-to-connect joints. In Canada, some lengths are available in galvalume steel outer pipe.
The double wall (pipe within a pipe) construction with its built-in air space, provides permanent insulation and keeps the inner pipe hot and the outer pipe relatively cool. This construction creates quick, strong vent action reducing condensation in the pipe and overheating of nearby enclosure surfaces.
