Abstract: A method of replacing an existing threaded coupler on an existing tubular fixture secured to a baghouse is provided to couple a pulse jet device to a blowpipe of the baghouse via the existing tubular fixture. The method includes the steps of disconnecting the blowpipe from the existing tubular fixture by removing the threaded coupler therefrom. The method further includes the steps of providing a spacer sleeve arranged co-axially within the existing tubular fixture, and providing a transfer tube arranged co-axially within the spacer sleeve. The method further includes the steps of coupling the transfer tube to the spacer sleeve, coupling the spacer sleeve to the existing tubular fixture, arranging the blowpipe within the spacer sleeve, providing a supply tube coupled to the pulse jet device, and coupling the supply tube to the transfer tube. In one example, the supply tube is flexible.
