Rectorseal 803-8 Galvanized Steel Duct Ring 8 Inch

Product Description

The RECTORSEAL 803-8 is a galvanized steel duct ring designed to provide a secure transition between 8-inch round duct and ceiling diffuser or grille assemblies. Constructed from galvanized steel, it resists corrosion and holds up to the demands of both residential and light commercial HVAC installations. The duct ring ensures proper diffuser attachment and a reliable airflow transition at the register opening. Licensed HVAC technicians and sheet metal installers typically specify this component during new construction and retrofit duct termination work.

The 803-8 is suited for residential and light commercial HVAC systems where an 8-inch round duct terminates at a ceiling, wall, or floor diffuser or grille assembly. It serves as the mechanical interface between the round duct run and the diffuser frame, maintaining alignment and a flush fit at the finished surface. This ring is a standard component in forced-air supply and return duct systems.

Key Features

• Galvanized steel construction for corrosion resistance and long service life
• Sized for 8-inch round duct terminations
• Facilitates secure attachment of ceiling diffusers and grille assemblies
• Suitable for residential and light commercial forced-air HVAC systems
• Supports consistent airflow transition at the diffuser face

Compatibility

Designed as an OEM-style replacement and standard installation component for 8-inch round duct terminations used with ceiling diffusers or grille assemblies in residential and light commercial HVAC systems.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal workers. Shut down the air handling unit and de-energize associated controls before beginning duct termination work. Secure the duct ring to the duct end and diffuser frame using appropriate sheet metal screws or fasteners per local mechanical code requirements. Follow SMACNA duct construction standards and applicable local codes for proper joint sealing and support.
