Sealed and/or Reinforced Flanged Ring Connector for Single- and Double-Wall HVAC Ducting

摘要

A flanged ring connector (50) for connecting adjacent ends of HVAC ducting (52) includes an insertion flange portion to engage within the interior of the ducting. A mating flange portion (56) extends laterally or transversely to the insertion flange portion (54).

主权项

1. A flanged ring connector to join ducts in an HVAC system, the flange ring connector comprising:
a. a first mating flange defining a first mating face, said first mating flange defining an outer perimeter portion and an inner perimeter portion; b. a first insertion flange extending laterally from the inner perimeter portion of the first mating flange, said first insertion flange having an inside surface and an outside surface, said first insertion flange having a sufficient length to allow fixed attachment to the HVAC duct; and c. a first formed seat extending along the first mating flange, said seat sized and shaped to receive one or both of the following within the seat:
(i) a seal to be disposed within and project from the first seat beyond the first mating face; and(ii) a reinforcing member disposed within the first seat to increase the structural integrity of the flanged ring connector.
