The Hi-Seas Mini Double Barrel Sleeves are precision-engineered crimping components designed for building professional-grade leaders and rigs. Featuring a black finish and double-barrel construction, these sleeves deliver superior holding power for big game monofilament, wire leader, and other line types.

Double-Barrel Strength

The dual-crimp design provides twice the holding surface of single sleeves, creating exceptionally strong connections that won’t slip or fail under extreme pressure. When you’re targeting billfish, tuna, or other powerful gamefish, this extra security gives you confidence that your leaders will hold through brutal strikes and extended fights.

Professional-Grade Construction

Hi-Seas manufactures these sleeves to exacting tolerances with a burr-free, nonabrasive finish that protects your line during crimping and use. The high-strength material resists corrosion in saltwater environments while maintaining consistent compression characteristics that professional tackle manufacturers demand.

Perfect for big game monofilament leaders, wire rigging, and various line types. Whether you’re building wind-on leaders for marlin, wire traces for wahoo and kingfish, or heavy mono leaders for tuna, these mini double-barrel sleeves provide the reliability and strength your rigs require.
