Seal-tite 697-07 Adjustable Ductboard Takeoff 7 in

Product Description

The SEAL-TITE 697-07 is a 7-inch adjustable ductboard takeoff fitting designed for use in low-pressure duct distribution systems. Takeoff fittings connect branch runs to a main duct trunk, directing conditioned air from the central supply plenum into individual zones or rooms. The adjustable design allows the fitting to seat properly against ductboard panels of varying thickness, making field installation more forgiving and reducing the need for custom cutting or shimming. Licensed HVAC technicians and sheet metal installers are the primary trades that work with this fitting.

This fitting is suited for residential and light commercial HVAC installations where ductboard fiber glass duct systems are specified. It is commonly installed during new construction or duct retrofit work where a flexible, adjustable connection point is needed at the branch takeoff location. The 7-inch size corresponds to the branch duct diameter, making it compatible with 7-inch round flex or rigid branch runouts in low-velocity supply air systems.

Key Features

• Adjustable design accommodates ductboard panels of varying thickness for a secure, airtight seat
• 7-inch diameter opening matches standard branch runout sizing in residential duct systems
• Designed for ductboard duct systems, avoiding the need for sheet metal trunk modifications
• Takeoff configuration supports low-pressure supply air branch connections

Compatibility

Designed as an OEM-style replacement and new-installation fitting for fiber glass ductboard trunk systems requiring a 7-inch adjustable branch takeoff connection.

Installation Notes

Installation of ductboard takeoff fittings is performed by licensed HVAC technicians or qualified sheet metal installers. The air handling system and associated electrical controls must be powered down before any duct work begins. The fitting should be secured and sealed to the ductboard surface per SMACNA ductboard installation standards and local mechanical code requirements. Do not operate the system until all takeoff connections are fully sealed with approved duct mastic or UL-listed foil tape.
