Imperial GV0734 Round Duct End Cap 4 Inch Galvanized

Product Description

The IMPERIAL GV0734 is a round duct end cap designed to close off the small crimped end of a round sheet metal pipe run. Constructed from 30-gauge galvanized steel, this cap installs directly onto the crimped end of a round duct using sheet metal screws for a secure, finished termination. It is a standard component in residential and light commercial HVAC duct fabrication and repair work, used wherever an open pipe end needs to be sealed cleanly and permanently. The galvanized finish resists corrosion in typical ductwork environments.

This end cap fits a 4-inch diameter round duct with a small crimped end profile. It is suited for low-pressure supply or return air duct systems in residential construction, renovation, and HVAC service applications. HVAC technicians and sheet metal installers reach for this part when capping unused branch takeoffs, sealing dead-end runs, or finishing rough-in ductwork during system commissioning.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified sheet metal installer. Shut down the air handling system and confirm the duct is depressurized before beginning work. Slide the cap over the crimped end of the duct and fasten with sheet metal screws at evenly spaced intervals around the perimeter. Follow local mechanical codes and SMACNA duct construction standards for fastener spacing and sealing requirements.
