Our Glidemaster brass valve fits the dual jet s-bend carpet extraction wand, and allows fluid to pass through the wand and be dispensed onto the carpeting. When the handle is released a spring is depressed, closing off the flow of liquid. The front of the valves screws onto the solution line of the hose, and a female quick disconnect, and a threaded barb are screwed into the back side of the valve. The female quick disconnect can then be attached to the solution line on the 25' vacuum/solution hose combo that came with your extractor.
A complete drawing of the drag wand assembly, and where this brass valve fits into that picture, can be found on the 1034-110015FB drag wand parts breakdown. For more parts for your carpet & upholstery tools, please check that breakdown, or take a look at our complete line of drag wand jets & parts.
