N.T NICKLE TWIN SLEEVE 361N
The N.T. Nickel Twin Sleeve 361N is a heavy-duty, double-barrel copper crimp sleeve engineered in Japan by N.T. Swivel for high-strength terminal rigging. Built with a figure-eight dual-channel profile and finished with a saltwater-grade nickel coating, the 361N delivers secure, non-slip connections on heavy monofilament, fluorocarbon, and multi-strand wire leaders without compromising line breaking strain.
Key Features
-
Figure-Eight Twin-Barrel Design: Dual separate channels isolate each line pass, eliminating line cross-over, pinch damage, and friction during crimping.
-
Burr-Free Interior Edges: Smooth, chamfered internal entry points prevent leader chafing, nicking, or premature shearing under heavy strike shock.
-
Seamless Marine-Grade Copper: Annealed copper construction compresses uniformly across cup-to-cup crimping dies for maximum tensile holding strength.
-
Corrosion-Resistant Nickel Finish (361N): Plated specifically to resist oxidation, pitting, and salt spray in offshore and tropical saltwater environments.
-
Precision Japanese Manufacturing: Built to tight tolerances for consistent wall thickness and predictable crimp compression.

Recommended Applications
-
Offshore Game Fishing: Connecting heavy wind-on leaders to ball-bearing swivels, solid rings, and trolling lures.
-
Tooth-Resistant Traces: Constructing short wire or heavy mono/fluoro shock leaders for pelagics such as tuna, wahoo, mackerel, and billfish.
-
Deep Drop & Bottom Rigs: Crafting multi-hook droppers, spreader bars, and assist hook assemblies where knots add excessive bulk or create weak points.
