The AFW Single Barrel Leader Sleeves are the clean, reliable way to finish a crimped leader connection. Whether you're rigging wire leaders for wahoo, building mono rigs for marlin, or setting up shark leaders, these single barrel sleeves give you a secure, professional crimp every time — no knots, no guesswork, no slippage. The Crimp That Holds When It Counts A properly crimped sleeve outperforms a hand-tied knot in both strength and consistency. AFW's single barrel design compresses evenly under a quality crimping tool, creating a connection that holds at or near the rated break strength of your wire or mono. For offshore applications where a failed connection means a lost fish — or a lost rig — that consistency matters. Why Knots Fall Short on Wire Wire leaders and heavy mono don't knot the way lighter line does. Knots in wire create stress points that weaken the connection and can fail under the sudden load of a hard-running fish. Crimping eliminates that weak point entirely — the sleeve distributes the load evenly and holds firm whether you're trolling at speed or fighting a fish that doesn't want to come up.

When in doubt, go up one size rather than down. Always use a quality crimping tool: Pliers or generic tools produce uneven crimps that can slip under load. AFW's dedicated crimping pliers are designed to compress these sleeves evenly for a connection that holds at full break strength. Pre-rig your leaders before the trip: With 36 sleeves per pack, you have plenty to build a full set of pre-rigged leaders at home. Store finished leaders on leader wheels so they're ready to swap quickly when conditions change or a leader gets damaged. FAQ What size sleeve do I need for my wire? Size #1 (.033") is suited for lighter wire (30–60 lb); size #2 (.047") works for mid-range wire (90–135 lb); size #3 (.055") is designed for heavy wire (170–250 lb) and large shark leaders. Always match the sleeve diameter to your wire or mono for the strongest crimp. Can I use these sleeves with monofilament or fluorocarbon leaders? Yes — AFW Single Barrel Sleeves work with both wire and heavy mono or fluorocarbon leaders. Select the size that matches your line diameter for a clean, secure crimp. Do I need special tools to crimp these sleeves? A dedicated crimping tool is strongly recommended. Generic pliers produce uneven crimps that can slip or fail under load. AFW's crimping pliers are designed specifically for these sleeves and will give you a consistent, full-strength connection every time.
