1. A flanged ring connector to join adjacent ducts in an HVAC system, the flanged ring connector comprising:
a. a mating flange defining a planar mating face, said mating flange also defining an outer perimeter portion and an inner perimeter portion;
b. an insertion flange extending laterally from the inner perimeter portion of the mating flange, the insertion flange having a length sufficient to allow fixed attachment to the interior of an HVAC duct;
c. a formed, enclosed seat extending around the outer perimeter portion of the mating flange, a portion of the seat being coplanar with the mating flange to serve as the radially outermost part of the mating flange, the seat extending from the mating flange in the direction that the insertion flange extends from the mating flange to define a cavity for receiving a reinforcing member; and
d. the reinforcing member disposed and securely held within the cavity of the formed seat to position the reinforcing member against the mating flange, wherein the seat closely surrounds the reinforcing member.
