Make the tippet to leader connection quick and easy and extend the life of your leader. Tippet Rings are a fast and easy system for changing the size of your tippet. Unlike a blood knot or double surgeon's knot, the use of a Tippet Ring allows a fly angler to connect a tippet that is significantly different in diameter than the end of the leader. For example, it's difficult to connect a 3X leader to a 7X tippet with a knot, but with the use of a Tippet Ring, it's quick and easy. These nickel alloy rings are very small, smooth and seamless connectors between your leader and tippet. Tie one on the end of your leader, then tie the tippet onto the ring These rings make changing or replacing tippet easy without nibbling away at the leader. They really have caught on among competitive fly fishers, because of the speed and ease with which tippet can be changed. May be used on any leader system and are excellent for tying droppers. Light enough to fish dry flies and midges on 7X tippets. In black. 3/32" or 2.5mm. 10 per pack.
