Faithfull Hose Clips are ideal for fixing flexible rubber hoses, plastic hoses and flexible pipes and can be used around the home, in the garden, workshop or the garage, in most applications where a water or air tight seal is required. The non-perforated worm drive used on these hose clips provides a high thread strength with a smooth running, snag-free winding surface. A hex shaped drive nut allows the use of either a slotted screwdriver, spanner, nutdriver or hose clip driver* when tightening or loosening the clips. Standard range hose clips are manufactured from mild steel and are zinc plated to aid corrosion resistance and are available in a wide variety of sizes. * The Faithfull Flexi-drive hose clip driver (product code: FAISDHOSE) is perfect for fitting and removing hose clips. The driver features a full sized, soft-grip, non-slip handle and a flexible drive shaft that allows easy access when removing or fitting hose clips in difficult to reach or offset positions.
