The 3RP3 is a 3″ ID × 3-1/2″ OD × 3-foot length, round, double-wall Type B gas vent pipe section manufactured by Hart & Cooley.  It is designed for venting gas-fired appliances under negative pressure conditions, up to flue temperatures of ~550 °F (not suited for oil, multi-fuel or incinerators). The unit features an aluminum inner wall (0.012″ thick) and a G-90 galvanized steel outer wall (0.018″ thick) for corrosion resistance and durability.  Ends are lock-ring style couplings, and when multiple segments are joined the assembled length is about 1 ?″ shorter than the listed 3-foot length (because of the overlap). Minimum clearance to combustibles is 1″.

This vent section is appropriate for residential or light-commercial HVAC venting systems that follow manufacturer and building code guidelines.
