Seal-tite 301-08 Airtite Takeoff 8 Inches Round Duct

Product Description

The SEAL-TITE 301-08 is an airtight duct takeoff fitting designed for 8-inch round duct applications in forced-air HVAC systems. Constructed from galvanized steel, it features a precision-engineered collar that creates a secure, leak-free connection at the trunk or plenum. Reducing air leakage at the takeoff point directly supports system efficiency and consistent static pressure throughout the distribution network. This fitting is installed by HVAC technicians in both residential and light commercial ductwork installations where reliable airflow delivery is required.

The 301-08 is suited for new construction and replacement ductwork projects involving 8-inch round branch runs. Its galvanized steel construction handles typical supply and return air temperature ranges found in residential and commercial forced-air systems. The airtight collar design minimizes uncontrolled air loss at branch connections, helping the system maintain designed airflow rates to each zone or register.

Key Features

• Precision-engineered collar provides an airtight, leak-free connection at the duct branch point
• Galvanized steel construction for durability in residential and commercial HVAC applications
• Sized for 8-inch round duct branch runs
• Designed to reduce energy loss caused by air leakage at takeoff connections
• Supports consistent airflow delivery across the duct distribution system

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 8-inch round duct branch connections in residential and commercial forced-air HVAC ductwork systems.

Installation Notes

Installation is performed by licensed HVAC technicians. Power down the air handling unit and close the system dampers before cutting into the trunk or plenum. Secure the takeoff collar to the duct with appropriate sheet metal screws and seal all joints with listed duct mastic or UL 181-rated tape in accordance with local mechanical codes and SMACNA standards. Do not rely on duct tape alone for an airtight seal.
