2.5" - 6" Duct Seal-Off Nozzle (Adapter Only, Seal-Off Body Not Included)

The 58420 series seal-off adapters prevent air from escaping to ensure maximum pressure for faster and more efficient line blowing. The 58420-030 adapter is designed for use in 2.5-inch to 6-inch ducts or conduits. Don't forget to order your 58420-040 seal-off body (sold separately) at the same time as your adapter for ease of compatibility and reduced down time.
