This type of increaser is used in single-wall metal vent systems to accommodate diameter changes within a venting assembly. Licensed HVAC technicians and plumbers install these fittings when connecting appliances or vent sections that require a step-up in pipe size. The 5RV-I8 designation confirms the inlet and outlet dimensions: 5 inches inlet, 8 inches outlet.\u003c\/p\u003e\n\u003cp\u003eThis increaser fitting is suited for residential and light commercial venting applications where a Type RV single-wall vent system requires a diameter transition. Common install scenarios include connecting a smaller-diameter appliance flue collar to a larger-diameter main vent trunk or chimney connector. It is appropriate for gas appliance venting within the system type and diameter range specified by the fitting designation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions vent pipe from 5 inches to 8 inches in a single fitting\u003c\/li\u003e\n  \u003cli\u003eType RV single-wall vent construction\u003c\/li\u003e\n  \u003cli\u003eDesigned for secure, leak-resistant connection within a vent assembly\u003c\/li\u003e\n  \u003cli\u003ePart number 5RV-I8 confirms inlet and outlet sizing for fast field identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade fitting for Type RV single-wall gas vent systems with a 5-inch inlet and 8-inch outlet requirement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and applicable fuel gas codes such as the IFGC.
