This fitting bridges the transition between flexible stainless steel or aluminum gas liner and double-wall Type B vent pipe, maintaining a continuous and code-compliant flue path. It is installed by licensed HVAC technicians or plumbers working on natural gas or propane appliance venting systems where a flexible liner connects to a rigid B-vent run.\u003c\/p\u003e\u003cp\u003eThis connector is suited for residential and light commercial venting applications involving gas-fired appliances such as furnaces, boilers, and water heaters. It is used when a flexible gas liner terminates at or transitions into a Type B vent section, a common scenario during liner retrofits of masonry chimneys or when extending an existing B-vent system with a flexible run.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch diameter fits standard 3-inch B-vent and matching flexible gas liner sizes\u003c\/li\u003e\n\u003cli\u003eDesigned specifically to adapt Z-Flex gas liner to Type B gas vent pipe\u003c\/li\u003e\n\u003cli\u003eMaintains a sealed flue transition for safe combustion gas routing\u003c\/li\u003e\n\u003cli\u003eCompact connector form factor simplifies tight-clearance installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to connect Z-Flex flexible gas liner to Type B gas vent systems.
