Seal-tite 115014 Starting Collar 14 Inches Long

Product Description

The SEAL-TITE 115014 is a round duct starting collar designed to create a 14-inch branch connection from a supply or return trunk duct. Installed into a field-cut opening in the trunk, it forms a secure take-off point for round rigid pipe or flexible duct. The long-body design provides increased insertion depth compared to standard collars, which helps maintain alignment and connection stability during installation. HVAC technicians and sheet metal installers use this fitting as a foundational component when branching off main duct runs in residential and light commercial forced-air systems.

This starting collar is suited for new construction and retrofit applications where a 14-inch round branch must be tapped off an existing or newly fabricated trunk duct. The long collar profile is especially useful in tight plenum spaces or where the branch duct requires added support at the connection point. It accepts standard 14-inch round pipe or appropriately sized flex duct, making it compatible with common duct system configurations across residential and light commercial HVAC installations.

Key Features

• 14-inch round opening sized for direct connection to standard round pipe or flex duct
• Long-body design provides greater insertion depth for a more secure duct connection
• Installs into a cut opening in supply or return trunk duct
• Functions as a take-off point in forced-air distribution systems
• Suited for both new construction and retrofit trunk duct applications

Compatibility

Designed as an OEM-style replacement and standard-fit starting collar for 14-inch round duct branch connections in residential and light commercial forced-air HVAC duct systems.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal installer. Power down the air handling unit or furnace before cutting into the trunk duct. Use appropriate sheet metal tools to cut a clean, properly sized opening in the trunk before inserting the collar. Secure the collar and connected duct per local mechanical code requirements, which may reference SMACNA standards for duct construction and installation.
