The Hart & Cooley 3RP5 is a 3-inch inside diameter, 5-foot length, Round Pipe (RP) Series B-Vent designed for gas-fired appliance venting applications. It consists of a double-wall, air-insulated construction (galvanized steel outer, aluminum inner) that meets UL 441 standards for Type B gas venting in negative-pressure or neutral-pressure installations with flue-gas temperatures less than approximately 400 °F above ambient (or up to about 550 °F in some references). This model is ideal for vertical (and some horizontal, with proper fan/draft control) installations of Category I gas-fired appliances. The product length is specified as 5 feet (60 inches) for the 3RP5 model.  Features include the locking joint/coupler system for secure ventilation runs and minimum clearance to combustibles of 1″ for standard sizes in the RP series. In summary: It's a robust, code-compliant vent pipe section for moderate-temperature gas appliances, offering a reliable and install-friendly solution for professionals in HVAC and venting systems.
