Seal-tite 1210-1610 Duct End Cap 16x10 Inches

Product Description

The SEAL-TITE 1210-1610 is a rectangular duct end cap designed to close off the open end of a flat-oval or rectangular duct section measuring 16 inches by 10 inches. It provides a secure, airtight termination point that prevents conditioned air loss and blocks debris, pests, and unconditioned air from entering the duct system. HVAC installers and sheet metal contractors use end caps like this during new construction, system modifications, and seasonal shutdowns to maintain system integrity and efficiency.

This end cap is suited for residential and light commercial HVAC ductwork applications where a 16-inch by 10-inch rectangular duct opening requires a clean, permanent closure. It is a common component in forced-air heating and cooling systems during trunk-line modifications, branch cap-offs, or when decommissioning a duct run. The part fits into standard low-pressure supply and return duct configurations typical of residential construction.

Key Features

• Closes a 16-inch by 10-inch rectangular duct opening for a complete air seal
• Prevents conditioned air loss at duct termination points
• Suitable for new installation, retrofit, and seasonal service applications
• Compatible with standard low-pressure residential and light commercial duct systems

Compatibility

Designed as an OEM-style closure for 16-inch by 10-inch rectangular duct openings in standard forced-air HVAC systems.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified sheet metal contractor. Power down the air handling system at the disconnect or breaker before working inside the duct. Seal the perimeter of the end cap with listed duct sealant or UL 181-rated tape per local mechanical code requirements. Do not use sheet metal screws alone as the sole means of air sealing.
