Centec 98691 8 Inch Pipe and Conduit Cleaning Nozzle with Locking Collar
An 8" curved cleaning nozzle designed to clean pipes, and conduit with a compression collar compatible adaptor attached to permit a mechanical lock of the tool onto the extension wand preventing unintended separation. 
Features and Benefits:
A 1.5" collar mounted on an 8 inch (200mm) curved pipe, conduit, and wire bundle cleaning nozzle.
A stiff nylon brush is centered in the cleaning opening running the full length of the curved portion of the tool. Centering the brush permits air to flow on both sides of the brush for more effective cleaning when the tool moves left or right across the surface.
An ABS collar feature permits the tool to lock into industry standard compression collars ensuring against unintended separation of the tool when working overhead.
