Seal-tite 1210-1210 Duct End Cap 12x10 Inches

Product Description

The SEAL-TITE 1210-1210 is a duct end cap sized at 12 inches by 10 inches, designed to close off the open ends of rectangular sheet metal ductwork. End caps of this type prevent uncontrolled airflow loss at duct terminations, keeping conditioned air where it belongs and maintaining system static pressure. This fitting is a standard component in low-pressure supply and return air distribution systems. HVAC sheet metal mechanics and duct installers are the primary trades that work with this type of fitting during new construction, renovation, or duct repair projects.

This end cap is suited for rectangular duct systems in residential and light commercial HVAC applications where a 12-inch by 10-inch duct termination point requires sealing. Typical use cases include capping unused duct branches, closing off supply or return openings during phased construction, or permanently terminating a duct run. The 12 by 10 inch opening dimension matches standard rectangular duct sizing common in forced-air systems.

Key Features

• Fits 12 inch by 10 inch rectangular duct openings
• Closes off duct terminations to prevent conditioned air loss
• Standard rectangular profile compatible with common sheet metal duct dimensions
• Suitable for low-pressure supply and return air duct systems

Compatibility

Designed as an OEM-style replacement fitting for standard 12 inch by 10 inch rectangular sheet metal ductwork used in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal mechanic. Power down the air handling equipment before working on the duct system. End caps are generally secured with sheet metal screws and sealed with UL 181-rated duct sealant or approved foil tape to meet code requirements. Follow all applicable local mechanical codes and SMACNA guidelines for duct construction and sealing.
