The small end is factory-crimped for straightforward insertion into the next flue section without additional field modification. Licensed HVAC technicians and plumbers install this fitting when connecting mismatched vent pipe diameters on single-wall black stovepipe or appliance connector runs. At 13.57 pounds per carton of 12 units, each reducer is lightweight enough for single-person handling during installation.\u003c\/p\u003e\u003cp\u003eThis reducer is intended for use in single-wall black flue pipe applications, including those serving wood-burning stoves, fireplaces, and solid-fuel or gas appliances that require a standard black steel connector. It fits into venting configurations where the larger 8-inch collar must step down to a 7-inch flue pipe, accommodating common vent diameters found in residential heating installations. Sold in cases of 12, it is a practical stocking item for HVAC distributors and service contractors who handle multiple installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteps down from 8 inches to 7 inches for standard flue diameter transitions\u003c\/li\u003e\n\u003cli\u003e24-gauge black steel construction suitable for single-wall flue connector applications\u003c\/li\u003e\n\u003cli\u003eFactory-crimped small end simplifies insertion into downstream pipe sections\u003c\/li\u003e\n\u003cli\u003eConsistent sizing across a 12-unit case pack supports high-volume stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fitting for single-wall black stovepipe and appliance connector systems requiring an 8-inch to 7-inch round flue reducer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified tradesperson in accordance with the appliance manufacturer instructions and applicable local codes, including the International Fuel Gas Code where required.
