Southwark Metal 55_8IN Duct Tee End Cap 8 Inch

Product Description

The SOUTHWARK METAL 55_8IN is a sheet metal duct tee end cap designed to terminate or cap off the end of an 8-inch diameter duct tee in forced-air HVAC distribution systems. Constructed from hot dip galvanized steel, this cap features a crimped end that allows it to slip securely over the tee branch outlet. It meets ACCA and SMACNA fabrication standards, making it a code-appropriate choice for residential and light commercial ductwork installations. HVAC sheet metal mechanics and duct installers use this component to close off unused tee branches or seal distribution points during system balancing or modification.

This end cap is suited for use in supply and return air duct systems where a tee branch requires permanent or semi-permanent closure. Typical applications include new construction ductwork, remodel projects where a branch is taken out of service, and system modifications requiring a clean, secure termination point. The crimped profile ensures a snug mechanical fit against the tee outlet without requiring additional fasteners in most installations.

Key Features

• Hot dip galvanized steel construction resists corrosion in typical HVAC duct environments
• Crimped end design provides a secure mechanical fit over the duct tee branch
• 8-inch diameter sizing matches standard round duct tee branch outlets
• Meets ACCA and SMACNA applicable standards for sheet metal ductwork fabrication
• Straightforward installation with standard sheet metal hand tools

Compatibility

Designed as an OEM-style sheet metal fitting for use with 8-inch diameter round duct tee fittings in residential and light commercial forced-air HVAC duct systems built to SMACNA and ACCA standards.

Installation Notes

Installation is typically performed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handling unit and ensure the system is depressurized before working on ductwork. Secure the cap over the tee branch outlet and fasten with sheet metal screws and foil-backed duct tape or mastic sealant as required by local mechanical code and SMACNA installation guidelines. Avoid over-crimping or forcing the cap, which can distort the fitting and compromise the seal.
