The SNAPPY 1510431 is a 6-inch galvanized oval flat 90-degree elbow used in sheet metal ductwork systems. This fitting makes a sharp directional change in oval duct runs while maintaining a low-profile flat configuration, making it well-suited for installations where ceiling or wall clearance is limited. Fabricated from galvanized steel, it resists corrosion in typical HVAC air distribution environments. HVAC sheet metal mechanics and duct installers use this fitting in forced-air residential and light commercial systems where oval duct is the preferred trunk or branch configuration.
This elbow is used in supply and return air duct systems utilizing 6-inch oval flat duct. The flat oval profile allows routing through framed cavities, crawlspaces, and tight interstitial spaces where round duct will not fit. It is a standard component in new construction and renovation ductwork layouts requiring a 90-degree change in direction without transitioning to a different duct shape or size.
Designed for use with 6-inch galvanized oval flat duct systems in residential and light commercial forced-air HVAC installations.
Installation should be performed by a qualified HVAC technician or sheet metal mechanic in accordance with SMACNA duct construction standards and applicable local mechanical codes. Power down the air handling system before making any duct connections or modifications. Secure the fitting using sheet metal screws and seal all joints with UL 181-rated duct tape or mastic sealant to maintain system pressure integrity. Avoid over-driving screws into the fitting collar, which can distort the oval profile and compromise the seal.
