Double Crimp Copper Sleeves Built for Serious Leader Rigging

These double crimp copper sleeves from Epic Fishing Co. are the real deal for building leaders that hold. Copper is the move over aluminum because it conforms tighter around your leader material without cracking or splitting under pressure. The double barrel design gives you two independent crimp points on every connection, so your loop stays locked even on hard drag runs. Available in five sizes from 1.0mm to 2.2mm, you can rig everything from 60lb kingfish leaders to 400lb blue marlin wind-on connections. Each bag has 100 sleeves, which is enough to build leaders for months. The black coating handles saltwater without corroding, and you can crimp these with a standard hand crimper. No bench crimper required.
  • Copper construction conforms tighter and holds stronger than aluminum sleeves
  • Double barrel design provides two crimp points per connection for maximum security
  • 5 sizes from 1.0mm to 2.2mm cover leaders from 60lb to 400lb test
  • Black corrosion-resistant coating built specifically for saltwater use
  • 100 count bags starting at $7.99 for serious rigging value

Perfect measurements and weight

Used this differently than its intended design. I made raft oars counter balances from them. Previously used steel 4lb mounted on the exterior near the grips. These I was able to install into the shaft and at 5lbs was able to get the weight away from the grips. Both oars took about 30 minutes. Another bonus is the seller got the weights to me in 4 days vice 12 Amazon predicted.

great bonito bait

Used these jigs this week and crushed the bonito on the east coast. This is a good bait to mimic the small bait fish in our area. Also great pack for a 2 pack. I bought a few different colors.

Awesome bait for Hybrid striped Bass.

Purchased these and first trip out boated several very nice Hybrids. The fish were in 5-7lb range. The bait falls fast and the hooks are very sharp for solid hook ups. Glad I had an extra one because I gave it to my buddy in the boat and he immediately hooked up. These baits worked so well, I ordered several more. I also referred several of my friends to the site to order this bait.

Quick delivery, great service

I live six hours from my boat in Swansboro and want my gear perfect when I step onto it a few times a month. I’ve counted on TheTackleRoom for many years to make sure I get what I need, when I need it before I head to the coast, and they have always delivered. I just received another order and am glad the level of service has stayed top notch.

Connections That Hold When It Counts

Every leader you build comes down to one thing: the crimp. You can use the best wire, the sharpest hooks, and the most expensive swivels, but if your crimp slips, none of it matters. That fish is gone and you're left staring at a curled-up piece of leader material.

Copper sleeves solve the problem that aluminum creates. Aluminum is cheaper, sure, but it cracks. It splits. It doesn't conform to the shape of your leader the way copper does. When you squeeze a copper sleeve down with your crimper, the metal flows around the leader and locks in place. It becomes part of the connection instead of just sitting on top of it.

These Epic Fishing Co. sleeves use a double barrel design, which means every crimp connection gets two separate compression points. That redundancy is why the pros use double sleeves on anything they care about landing. From 60lb kingfish rigs to 400lb marlin leaders, there's a size here that fits. And at 100 sleeves per bag, you're paying pennies per connection.

Copper Beats Aluminum Every Time

Aluminum crimp sleeves are cheap for a reason. They crack under pressure and don't conform well to leader material, which leaves gaps where your leader can slip. Copper is a softer, stronger metal that flows around mono, fluorocarbon, and wire when compressed. The result is a tighter crimp with more surface contact and zero air gaps. That translates directly to holding power. If you've ever had an aluminum sleeve split on a big fish, you already know why copper is worth the upgrade.

Five Sizes for Leaders 60lb to 400lb

Matching sleeve size to leader diameter is critical. Too big and the crimp won't compress properly. Too small and you can't thread the leader through. These come in five sizes that cover the full range of saltwater leader work. The 1.0mm fits 60-100lb leaders for kingfish and cobia rigs. The 1.3mm handles 100-150lb for tuna and wahoo. The 1.6mm covers 150-220lb for big game trolling. The 1.9mm fits 220-300lb for heavy marlin leaders. And the 2.2mm is built for 400lb wind-on connections and shark rigs.

100-Pack Value with Saltwater-Ready Coating

At $7.99 to $12.99 per 100-pack depending on size, you're paying 8 to 13 cents per sleeve. That's the kind of pricing that lets you rig leaders without thinking about waste. Pre-made leaders from tackle shops cost $8-15 each. Build your own and the sleeves are the cheapest part of the equation. The black coating on these sleeves isn't just cosmetic. It provides a corrosion barrier that keeps the copper from reacting with saltwater over time. Your crimps stay strong trip after trip.

How to Crimp Leaders with Double Sleeves

1. Select the right sleeve size for your leader diameter. 1.0mm for 60-100lb, 1.3mm for 100-150lb, 1.6mm for 150-220lb, 1.9mm for 220-300lb, 2.2mm for 400lb.

2. Thread your leader through both barrels of the sleeve, then pass it through your hook eye, swivel, or thimble, and back through both barrels again to form a loop.

3. Position the sleeve snug against the loop. Leave just enough space for the loop to pivot freely on the hardware, but no excess slack.

4. Crimp each barrel separately using a hand crimper. Start with the barrel closest to the loop, then crimp the second barrel. Use firm, even pressure.

5. Test the connection by pulling hard on both sides. A good crimp won't budge. If the leader slips at all, cut it off and start over.

Which sleeve size do I need for my leader? +
Match the sleeve to your leader pound test: 1.0mm for 60-100lb, 1.3mm for 100-150lb, 1.6mm for 150-220lb, 1.9mm for 220-300lb, and 2.2mm for 400lb. When in doubt, check our leader weight chart to match leader size to your target species.
Why are copper crimp sleeves better than aluminum? +
Copper is a softer metal that conforms tighter around your leader material without cracking or splitting. Aluminum tends to fracture under compression, leaving gaps where the leader can slip. Copper flows around the leader and creates more surface contact, which means stronger hold. Learn more about leader construction in our fishing leader FAQ.
How many crimps should I make on each double sleeve? +
Crimp each barrel separately for a total of two crimps per sleeve. Start with the barrel closest to the loop, then crimp the second barrel. Two crimps on a double barrel sleeve gives you redundancy that a single crimp can't match. Our step-by-step crimping guide walks through the full technique.
Do I need a bench crimper or will a hand crimper work? +
A quality hand crimper works perfectly for all five sizes of these sleeves. Bench crimpers are nice for high-volume rigging shops, but they're not necessary. The Epic 10" Hand Crimper is designed to pair with these sleeves and gives you clean, even compression every time.
Will these sleeves corrode in saltwater? +
The black coating provides corrosion resistance specifically for saltwater use. Uncoated copper will eventually react with salt and moisture, but this coating creates a barrier that keeps sleeves strong trip after trip. Store your pre-made leaders in a dry bag between trips and they'll last a long time. See our guide on wire vs mono leaders for saltwater for more rigging tips.
Can I use these copper sleeves on wire leaders? +
Absolutely. Copper sleeves are actually the standard choice for wire leader crimping because copper conforms around the individual wire strands better than aluminum. Whether you're using single-strand or 49-strand cable, just match your sleeve size to the wire diameter. Read our wire vs mono leader guide for sizing details.
How do I test if my crimp is good? +
After crimping both barrels, grab both sides and pull hard. A properly crimped sleeve will not move at all. If the leader slips even slightly, cut it off and redo it. You can also look at the crimp visually: it should be evenly compressed with no cracks or bulges. Our crimping guide covers testing in detail.
Is 100 sleeves per bag actually a good value? +
At 8 to 13 cents per sleeve depending on size, this is one of the cheapest components in any leader build. A single pre-made trolling leader costs $8-15 at most tackle shops. Build your own and the sleeves for 10+ leaders cost less than one pre-made rig. Check out our trolling spread rigging guide to see how many sleeves a typical spread uses.
