Removable extension hose. Our foam gun with valve has a total length of 63 cm/24.8 inches and consists of a 32.5 cm/12.80 inch long main spray gun and a corresponding extension hose 31 cm/12.2 inches long. The removable extension tube allows for greater reach in hard-to-reach areas, allowing you to decide whether to install it or not according to your needs. Easy Cleaning. The inside and outside of the expandable PU foam gun are coated with PTFE coating, which ensures non-stick properties and prevents the formation of residue. So no foam cleaner is needed when using the gun alone, saving you time and money. When using the extension tube, clean it with the long brush provided to prevent blockages. Waterproof Design. Our metal construction foam gun has a sealed valve. By closing the valve, the passage is blocked, and by further spraying, the remaining foam is discharged without the need for cleaning. Excellent Workmanship. The coated construction foam gun is made of high-strength aluminum alloy to ensure wear resistance. It features a brass nozzle and easily adjustable flow regulator for precise foam control, minimizing waste. Note: The foam gun uses a threaded fitting and is not compatible with foam cartridges without threads. Versatile applications. The expanding foam gun is ideal for filling gaps, sealing doors and windows and thermal insulation. It is widely used for installation, renovation and sealing of balcony doors/windows, bathtubs, air conditioning openings, roofs, interior/exterior walls, ceilings and fireplaces, and is an indispensable tool for construction and renovation projects.
