Crimps

Izorline Single Premium Aluminum Sleeves are perfect for monofilament lines using the ratings below.  Simply match the sleeve with the slot in the crimper and give it a firm hand shake.  Be careful not to get close to the edges of the sleeve, just crimp the middle of the sleeve.

Billfisher Aluminum Single Sleeve. Highest quality soft aluminum sleeves that work great with monofilament or fluorocarbon.  When crimping, make sure not to get close to the ends of each sleeve or it may cut into your line when fighting the fish.

The All-In-One Crimp Solution for Serious Offshore Anglers

When you're rigging for long range, heavy tuna, or kite fishing, your terminal connections have to hold. The Izorline Complete Crimping Kit gives you everything in one box — the right crimps, the right chafe protection, and the right tool — so you're never caught short on the water.

Built for Offshore Rigging

This kit covers the full range of offshore rigging needs, from lighter 80lb setups to heavy 400lb connections. Whether you're rigging wind-on leaders, kite clips, or heavy mono topshots, this kit has the crimp and chafe guard for the job. The included Izorline crimper is matched to every sleeve in the kit, so you're always using the right tool for the right crimp.

When Mono Connections Fail

Poorly crimped connections are one of the most common causes of lost fish offshore. Undersized crimps, wrong-gauge sleeves, and chafed mono at the crimp edge all lead to failures at the worst possible moment. This kit eliminates the guesswork — every sleeve is sized and matched, and the anti-chafing springs are lab-tested to increase monofilament break strength by up to 12%.

Aluminum Sleeves + Anti-Chafe Springs = Stronger Connections

The aluminum sleeves in this kit are engineered for monofilament and fluorocarbon — not braid. They compress with a firm, controlled squeeze; no need to over-crimp. The key is leaving 1/16" to 1/8" from both edges of the crimp to prevent stress fractures. Pair that with the included braid tube chafe guards and anti-chafing springs, and you've got connections that hold under serious pressure.

Tackle Express Tips

• Don't crimp to the edge. Always leave 1/16" to 1/8" from both ends of the sleeve to prevent stress fractures and connection failure.
• Match the sleeve to the line. These aluminum sleeves are designed for mono and fluorocarbon only — using them on braid will result in slippage. Use braid-specific sleeves for braid connections.
• Use the chafe guards every time. The anti-chafing springs aren't optional — they're what gives you that extra 12% break strength. Thread them on before crimping.

FAQ

Can I use these crimps with braided line?
No — the aluminum sleeves in this kit are designed for monofilament and fluorocarbon only. Braid requires a different sleeve type. Use the included braid tube chafe guards for chafe protection on braid sections, but crimp only mono or fluoro.

What's the correct technique for crimping?
Use a firm, even squeeze — not a death grip. Avoid crimping all the way to the edge of the sleeve; leave 1/16" to 1/8" on both ends. This prevents stress fractures and keeps the connection at full strength.

Does the kit include everything I need to start rigging?
Yes. The Izorline Complete Crimping Kit includes crimps from 80lb to 400lb, matching braid tube chafe guards, anti-chafing springs, and an Izorline crimper — everything you need to build solid offshore connections right out of the box.

The Sea Striker Billfisher Double Sleeves are great for attaching lures and hooks to heavy line without knots.  If crimped correctly, a sleeved line is stronger than a knot and has 100 percent breaking strength.  

You will notice on the line sizes below that there is no 100lb crimp.  It's because of the way that the sleeves are manufactured and aren't made at the 100lb diameter.  It is better to go with a little bigger crimp than a little smaller crimp, but they both will work.  

Another option is to use an aluminum sleeve since it's softer and has a greater tolerance to differing line sizes.  The The Sea Striker Billfisher Double Sleeves shown here are made of brass and are able to create a connection with a smaller profile.  Aluminum sleeves are longer so it comes into more contact with the line.  In the end, it's just personal preference as to what kind of sleeve you use.

If you ever find yourself looking for new set of Toit Fishing Crimpers, Crimping Pliers or a Swagger, ask a couple of questions first. What is torque and compressive strength? Torque rotational force represents the capability of force to affect something in a rotational motion. Compressive strength is basically the amount of load a specific area of a material can bear.

These 2 areas were the most essential problems to solve with the design strategy of our crimping pliers. The reduced surface area at the business end, in conjunction with the short distance to the pliers fulcrum (pivot point where pliers rotate), has allowed us to maximize torque and deform crimps. This easily allows us to crimp 400lb Multi-strand Stainless Cable and 400lb Mono or Fluoro leader material using either aluminum, copper or brass crimps. And it fits in your pocket!
