In order to insert the olive into Speed-Flex Hose, the stainless protective braid must be separated from the PTFE liner. This can be more difficult than it sounds. Earl's braid spreader solves the problem and eliminates the tiresome probability of poking holes in your fingers. In use, the tool is simply inserted into the cut end of the hose and pushed â€" spreading the braid. The olive is then placed on the tool mandrel, pushed over the hose liner, and under the braid until the liner bottoms against the shoulder of the olive.
