Seal-tite 106012 Round Galvanized Tee Joint 12 Inch

Product Description

The SEAL-TITE 106012 is a round galvanized metal tee joint designed for use in residential and light commercial HVAC duct systems. Constructed from 24-gauge galvanized metal, this tee fitting connects three sections of 12-inch round ductwork in a standard tee configuration. It is used to split or combine airflow at a junction point in a supply or return air trunk line. Licensed HVAC technicians and sheet metal mechanics install this fitting as part of a ducted forced-air system. The 24-gauge construction provides the rigidity required for a secure, long-lasting connection in both new construction and retrofit applications.

This tee joint is sized at 12 inches on all three openings, making it suitable for large-diameter round duct runs in residential and light commercial forced-air systems. It conforms to CCR/Title 24 and IECC applicable standards, which are commonly required in energy-code-compliant HVAC installations. Typical install scenarios include trunk-to-branch transitions in supply plenums, exhaust systems, and ventilation networks where a full 12-inch diameter must be maintained through the tee. No crimp is supplied with this fitting.

Key Features

• 24-gauge galvanized metal construction for durability and corrosion resistance
• All three openings are 12 inches for consistent airflow diameter through the tee
• Round duct shape compatible with standard spiral and snap-lock round duct
• Meets CCR/Title 24 and IECC applicable standards for energy-code-compliant installations
• No crimp supplied — field-crimped connections allow flexible installation sequencing

Compatibility

Designed as an OEM-style replacement and standard fitting for 12-inch round duct systems in residential and light commercial HVAC, ventilation, and exhaust applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Shut down and lock out the air handling unit before making duct connections. Seal all joints with UL 181-rated mastic or approved metal foil tape per applicable IECC and local mechanical code requirements. Field-crimp one or more openings as needed to allow for slip-fit assembly into adjacent duct sections.
