Berkley FireLine Fused Original 0.25mm 18.4kg 300m Crystal

Berkley FireLine Fused Original — 5× tougher than conventional braid

The Berkley FireLine Fused Original combines eight micro-strands into a smoother, more abrasion-resistant superline. At 0.25 mm diameter and 18.4 kg breaking strain, this 300 m Crystal spool delivers long-distance casting and instant bite detection for spinning and baitcasting setups in freshwater.

Unmatched abrasion resistance for hard cover

Fused 8-strand technology bonds the fibres together rather than simply braiding them, creating a line that withstands rock edges, mussels, and wood five times better than conventional braids. You can fish confidently around structure without constant retying.

Zero stretch for direct contact

With 0% stretch, every tap, tick, and headshake transmits straight to your rod tip. You'll set hooks faster and feel bottom composition clearly—crucial for finesse presentations and vertical jigging where sensitivity makes the difference between a catch and a missed opportunity.

Choose the right variant

Berkley FireLine Fused Original is available in multiple diameters, breaking strains, colours, and spool lengths to match your tackle and target species. Select based on your fishing style:

• 0.12 mm / 7.2 kg (150 m, 300 m, 1800 m) — all-round finesse for perch, zander, bass

• 0.15 mm / 8.3 kg (150 m, 300 m, 1800 m) — versatile choice for zander, pike, medium-sized predators

• 0.17 mm / 10.7 kg (150 m, 300 m, 1800 m) — heavier lures, deeper water, larger zander and pike

• 0.20 mm / 13.9 kg (150 m, 300 m, 1800 m) — 0.25 mm / 18.4 kg (150 m, 300 m, 1800 m) — pike, big zander, medium predators in weedy or snaggy water

• 0.32 mm / 24.6 kg (150 m, 300 m, 1800 m) — heavy pike, catfish, big-bait presentations

• 0.39 mm / 29.1 kg (150 m, 300 m, 1800 m) — large catfish, extreme cover, trophy hunting
