ABSTRACT:
A flex-duct end connector for connecting flex-ducting to fittings includes a cylindrical pipe and a pair of clamps configured to be mounted on the outside of the pipe. The outer surface of the pipe and the inner surfaces of the clamps may be provided with an adhesive to improve the connection. Outer wraps attached to the outside of the pipe include an adhesive side and a non-adhesive side. One end of the pipe may be tapered and the other end may include a rubberized coating. To connect the flex-ducting to the fitting, the insulation and outer jacket of the flex-duct is folded back from the liner. The liner slides over one end of the pipe. Adhesive may be provided on the pipe to provide a more secure fit. The clamps, which may also be provided with adhesive, are applied to the liner and pipe. The edges of the clamps overlap so that a fastener may be inserted through the clamps, the liner and the pipe. The insulation and outer jacket are then pulled over the clamps, and the outer wraps are deployed so that the adhesive side of each is applied to the outer jacket. The other end of the flex-duct end connector is inserted in the fitting. Zip ties or the like may be used at various points of the connecting process.
