Seal-tite 217-08 T-joint Crimp on Run 8 in 24 Gauge

Product Description

The SEAL-TITE 217-08 is a T-joint crimp-on run fitting designed for use in sheet metal ductwork fabrication and installation. This fitting connects a branch run to a main duct trunk at a 90-degree tee configuration, secured with a crimp-style connection for a snug, low-leakage fit. Constructed to 24-gauge specification, it suits standard residential and light commercial duct systems where rigid metal duct is specified. HVAC installers and sheet metal contractors use this fitting during new construction and retrofit duct runs where a branch takeoff is required.

The 217-08 is sized at 8 inches to match standard round duct diameters common in residential forced-air systems. It is appropriate for supply and return duct configurations and is used where a branch must be added to an existing trunk line or where a multi-leg duct layout is being fabricated from scratch. The crimp-on design keeps installation straightforward and does not require additional couplers at the joint seam.

Key Features

• T-joint configuration provides a clean branch takeoff from a main duct trunk line
• Crimp-on run design allows secure, tool-assisted connection without separate couplers
• 8-inch diameter fits standard round duct used in residential and light commercial HVAC systems
• 24-gauge construction provides structural rigidity appropriate for forced-air duct systems

Compatibility

Designed as an OEM-style fitting compatible with standard 8-inch round rigid metal ductwork in residential and light commercial forced-air HVAC installations.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal workers. Shut down the air handling unit and confirm the system is depressurized before fitting new duct sections. Secure all joints with sheet metal screws and seal with listed duct mastic or UL 181-rated tape per applicable mechanical codes. Avoid relying on duct tape alone as a primary sealant on metal ductwork.
