Castle Farriers Choice Mixing Tips are a dual forced champer mixing tip for use with 200ml cartridges. These 6'' long tips have a dedicated nozzle for each side of the material to be injected through before they start mixing. This eliminates the concern for contamination from either side. The tip is keyed to fit into the cartridge only 1 way and the retaining cap slides on and a simple quarter turn holds everything in place. Also compatable with Hoof-Tite brand adhesives. Comes in packs of 12.
