Fabricated from 24-gauge galvanized metal, this fitting delivers a rigid, corrosion-resistant connection point where a branch run intersects a main duct line. The crimp is supplied on the run outlet, allowing direct insertion into standard round pipe sections without additional fittings. HVAC sheet metal installers and duct fabricators use this tee in both new construction and retrofit duct systems where a reliable, code-compliant branch connection is required.\u003c\/p\u003e\n\u003cp\u003eThis tee joint is used on round sheet metal pipe in residential and light commercial forced-air HVAC duct systems. It suits supply and return trunk-and-branch layouts where a straight run requires a perpendicular branch takeoff at equal diameter. The 12-inch size is common in larger residential systems and small commercial applications where main trunk lines carry significant airflow volume. Installers working under CCR\/Title 24, IECC, HARDI, ACCA, AHREXPO, or ADI standards will find this fitting meets the applicable requirements for those specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12 x 12 x 12 inch equal-diameter tee for consistent airflow through run and branch\u003c\/li\u003e\n  \u003cli\u003e24-gauge galvanized metal construction for rigidity and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eCrimp supplied on the run outlet for direct insertion into round pipe\u003c\/li\u003e\n  \u003cli\u003eMeets applicable standards including CCR\/Title 24, IECC, HARDI, ACCA, AHREXPO, and ADI\u003c\/li\u003e\n  \u003cli\u003eUsed on standard round sheet metal pipe — no special adapters required for same-size connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 12-inch round sheet metal duct pipe in forced-air HVAC distribution systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or certified sheet metal workers. Power down the air handling unit and verify the system is depressurized before cutting into an existing duct line.
