Carlisle HVAC Products has released the Cartridge Killer extrusion gun kit, which provides applicators with a quick way to apply a fine bead of Spray-Seal Duct Sealant to boots, wyes and other fittings. The tool allows users to apply sealant via a spray-pump system, providing consistent bead sizes and eliminating the need for manual caulking guns. The lightweight, hand-held extrusion gun features a forward-facing trigger that controls application, and the rotating swivel allows users to apply sealant from any angle without kinking or binding the spray hose. Cartridge Killer’s specially designed tips—0.012, 0.017 and 0.022 inch—can be placed directly in the joint or seam being sealed.
