Jinkai Crimp Sleeves are made from a special aluminum alloy so they are easy to crimp and resistant to corrosion in saltwater. Together with a quality crimping (swagging) tool, these soft metal oval shapes sleeves compress to make the ultimate connection. Available in a wide variety of sizes, the line must match the sleeve. Great for all monofilament and fluorocarbon line rigging situations, especially big game fishing. These are not the best for stainless cable rigging. In these cases use a copper double barrel crimp. 

Size Chart - Line tests listed are for Jinkai's line which tends to be slightly thinner than other brands. Be sure to confirm your line diameters.
