Royal Building Products 35-97 8 in Street 90 Degree Elbow

Product Description

The ROYAL BUILDING PRODUCTS 35-97 is an 8-inch single-duct gasket street 90-degree elbow fitting used in duct and ventilation systems. This fitting provides a 90-degree directional change in a duct run, using a gasketed street configuration that allows one end to insert directly into a matching fitting without a separate coupling. HVAC installers and sheet metal contractors use this type of elbow when routing ductwork around obstructions or making turns in tight spaces. The gasketed design helps maintain an airtight seal at the joint, reducing air leakage in the duct system.

This elbow is sized for 8-inch single-duct applications, making it appropriate for residential and light commercial HVAC duct systems where a standard 90-degree turn is required. It is commonly installed in supply or return air duct runs where the duct path must change direction. The street-end configuration simplifies the connection at one end of the fitting, reducing the number of components needed in a run.

Key Features

• 8-inch duct diameter for compatibility with standard single-duct systems
• 90-degree elbow provides a square directional change in duct routing
• Street configuration allows direct insertion into a mating fitting without an additional coupling
• Gasketed joint design supports airtight sealing at the connection
• Suitable for supply or return air duct applications in residential and light commercial systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 8-inch single-duct ventilation and HVAC duct systems requiring a gasketed street 90-degree elbow connection.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with applicable mechanical codes. Power down and lock out the air handling unit before working on any connected ductwork. Ensure the mating fitting is clean and free of debris before inserting the street end to achieve a proper gasket seal. Follow local mechanical code requirements for duct joint sealing and support spacing.
