Seal-tite 301-06 Airtite Takeoff 6 Inches Round Duct

Product Description

The SEAL-TITE 301-06 is a 6-inch airtite duct takeoff fitting designed for round duct systems in residential and light commercial HVAC installations. Constructed from galvanized steel, it features a precision-fit collar that forms a secure, airtight connection at the trunk or plenum, minimizing conditioned-air leakage and supporting proper system static pressure. The tight collar fit reduces energy loss caused by unsealed duct joints and contributes to overall system balance. HVAC technicians install this fitting during ductwork fabrication or retrofit when branch runs require a reliable, low-leak connection point off a main trunk line.

The 301-06 is suited for residential forced-air systems and light commercial duct layouts where 6-inch round branch ducts are used. It is a practical solution for new construction duct runs and retrofit applications where an existing takeoff connection needs to be replaced or upgraded to reduce air leakage. Its galvanized steel construction holds up in attic, basement, crawlspace, and mechanical room environments where temperature swings and humidity are factors in long-term fitting performance.

Key Features

• Airtight collar design reduces conditioned-air leakage at branch duct connections
• Galvanized steel construction resists corrosion in typical HVAC install environments
• Precision-fit 6-inch collar seats securely without excessive fasteners or sealant
• Compatible with standard 6-inch round duct for straightforward branch connections
• Suitable for residential and light commercial forced-air system ductwork

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 6-inch round duct branch connections in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified sheet metal mechanic. Power down the air handler or furnace at the disconnect before working on the duct system. Secure the takeoff to the trunk or plenum using self-tapping sheet metal screws and seal all joints with listed duct mastic or UL 181-rated tape per applicable mechanical code requirements. Do not rely on friction fit alone as the sole means of retention in pressurized supply systems.
