Duct fittings

摘要

Duct fittings can be formed or assembled from two or more components including a collar and a clamp. The clamp and the collar can be assembled and/or mated together to form the duct fittings. The collar can have a first annular portion to which a first layer of a multilayered duct is attached or connected. The collar also can include a second annular portion that can include splines to which a second layer of the multilayered duct is attached. The splines can accommodate or form fluid passageways. The clamp can be located on top of the second layer and can include attachment mechanisms securing the clamp to a support surface.

1. A duct fitting comprising:
a collar comprising a first annular portion comprising a support surface for engaging a first layer of a multilayered duct and a second annular portion comprising a plurality of splines having voids formed therebetween, wherein the splines are configured to support a second layer of the multilayered duct; and a clamp disposed around the collar and independent from the collar, the clamp comprising an attachment mechanism configured to connect the clamp to a support structure, wherein the clamp is configured to cooperate with the collar to secure the second layer of the multilayered duct between the clamp and the collar such that opposing sides of the second layer abut the clamp and the splines of the collar.
