Seal-tite 1210-1010 Duct End Cap 10 X 10 in

Product Description

The SEAL-TITE 1210-1010 is a duct end cap sized at 10 inches x 10 inches, designed to close off the open end of a rectangular duct section. End caps are used to terminate duct runs cleanly, preventing airflow loss and blocking unconditioned air, debris, and pests from entering the duct system. This fitting is a standard component in low-pressure HVAC duct assemblies and is typically installed by sheet metal workers, HVAC technicians, or mechanical contractors during new construction or system modification.

This end cap fits 10-inch x 10-inch rectangular duct openings and is suited for residential and light commercial HVAC applications. It is used wherever a duct branch or main trunk requires termination, including supply and return plenums, trunk line endings, and capped-off branch takeoffs during phased construction or renovation projects.

Key Features

• Closes open rectangular duct ends to prevent air leakage and contamination
• 10 inches x 10 inches nominal size fits standard rectangular duct dimensions
• Suitable for low-pressure supply and return duct systems
• Straightforward installation with standard sheet metal fasteners and duct sealant

Compatibility

Designed as an OEM-style replacement and standard fitting for 10-inch x 10-inch rectangular duct assemblies in residential and light commercial HVAC systems.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal mechanic. Power down the air handling unit and close the system dampers before fitting the end cap to avoid pressure-related displacement during installation. Secure the cap with sheet metal screws and seal all edges with UL 181-rated duct sealant or mastic to meet code requirements. Follow local mechanical codes and SMACNA ductwork standards for proper fastening and sealing practices.
