Hart Cooley 16405 Round Gas Vent Pipe 7x8x12 Inch

Product Description

The HART COOLEY 16405 is a round gas vent pipe section from the RP Series, designed for venting gas appliances in residential and light commercial heating systems. Constructed from a steel and aluminum composite with a G90 galvanized finish, this pipe section measures 7 inches inner diameter, 8 inches outer diameter, and 12 inches in length. The galvanized coating provides corrosion resistance in flue gas environments. Wall thickness runs 0.012 inches on the aluminum layer and 0.018 inches on the steel layer. This section handles continuous flue gas temperatures up to 400 degrees F, making it appropriate for natural gas and propane appliance venting applications.

This pipe section is used in B-vent and Type L gas vent systems serving gas furnaces, water heaters, boilers, and similar appliances that require round vent pipe with a 7-inch nominal diameter. The 12-inch section length makes it useful for short runs, offsets, or completing a vent assembly where a full-length section is not required. Installation is typically performed by licensed HVAC technicians or plumbers working on gas appliance venting systems in residential or small commercial settings.
