What type of connectors are specified to control noise and vibrations in metal ductwork?

Flex connectors are specifically designed to control noise and vibrations in metal ductwork. These connectors allow for some degree of movement and flexibility, which helps to absorb vibrations that might otherwise be transmitted through the metal ductwork. This is particularly important in HVAC systems where equipment operation can generate significant sound and movement, leading to unwanted noise throughout a building.

Additionally, flex connectors can accommodate misalignment between duct sections or between the duct and the fan or air handler, which helps prevent stress on the duct system. This flexibility not only enhances the comfort levels in a space by minimizing noise but also contributes positively to the longevity of the HVAC system by preventing potential damage due to rigid connections.
