This swivel wye measures 6 inches by 5 inches by 3 inches and features a round, double-wall construction with an aluminum alloy inner wall at 0.012 inches thick and a G90 galvanized steel outer wall at 0.018 inches thick. The Sure-Lock twist-lock connection with integrated locking tab eliminates the need for sheet metal screws, reducing installation time and the chance of connection failure. Licensed HVAC technicians and gas appliance installers work with this fitting when routing B-vent systems around offsets or when branching vent runs.\u003c\/p\u003e\n\u003cp\u003eThe 6M5SY3 is suited for Type B gas vent systems serving natural gas and propane appliances such as furnaces, water heaters, and boilers. The swivel design allows field adjustment of the branch angle, which is especially useful when rough-in dimensions require flexibility. The double-wall configuration maintains the required air space between the flue gas path and the outer casing, supporting proper draft and surface temperature management. This fitting is applicable in both new construction and retrofit B-vent installations where a wye branch connection is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSure-Lock twist-lock connection with locking tab — no sheet metal screws required\u003c\/li\u003e\n  \u003cli\u003eDouble-wall construction: aluminum alloy inner wall and G90 galvanized steel outer wall\u003c\/li\u003e\n  \u003cli\u003eSwivel design allows field adjustment of branch angle during installation\u003c\/li\u003e\n  \u003cli\u003eHemmed flues and casings for added durability and reduced installation time\u003c\/li\u003e\n  \u003cli\u003eTested and listed to UL 441 for use with approved gas appliances\u003c\/li\u003e\n  \u003cli\u003eCompliant with NFPA 54 and NFPA 211 applicable standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Type B double-wall gas vent systems with approved natural gas and propane appliances.
