Duro Dyne 10031 Flexible Duct Connector Hvac Vibration Isolator

Product Description

The DURO DYNE 10031 is a fabric-based flexible duct connector designed to isolate vibration and airborne noise between mechanical HVAC equipment and the connected sheet metal ductwork. Measuring 1-3/4 x 3 x 1-3/4 inches, it consists of a flexible fabric section bonded to sheet metal flanges on both ends, forming an airtight joint that absorbs movement and dampens sound transmission. This type of connector is a standard component in any air handling installation where a fan or blower is present, preventing equipment vibration from traveling through the duct system and into occupied spaces.

The 10031 is suited for use in residential and light commercial heating, cooling, and ventilation systems. It installs between the air handling unit, furnace fan section, or blower cabinet and the adjacent sheet metal supply or return ductwork. Any installation where fan or blower vibration must be controlled before it enters the duct distribution system is an appropriate application for this connector.

Key Features

• Airtight flexible joint isolates fan and blower vibration at the source
• Fabric construction absorbs movement and prevents noise transmission into ductwork
• Sheet metal flanges on both sides allow direct connection to standard duct sections
• Compact 1-3/4 x 3 x 1-3/4 inch profile fits tight equipment clearances
• Suitable for heating, cooling, and ventilation duct applications

Compatibility

Designed as an OEM-style replacement or new-installation flexible duct connector for residential and light commercial HVAC systems where a fabric vibration isolator is required between blower equipment and sheet metal ductwork.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power to the air handling unit or furnace must be disconnected before beginning work. The connector should be secured to both the equipment collar and the duct section using appropriate sheet metal fasteners and sealed with duct tape or mastic rated for the application. Refer to local mechanical codes and SMACNA guidelines for flexible connector installation requirements.
