Frequently Asked Questions

Q: What sizes does this flare nut wrench cover?

A: This double-head open-ring spanner covers sizes from 8mm to 19mm. Each individual wrench features two different sizes on a single handle, maximising coverage while minimising toolbox space.

Q: What makes a flare nut wrench better than a standard open-end wrench for brake lines?

A: A flare nut wrench (also called a line wrench) has an almost-closed ring head with a small opening that slides over tubing. This design wraps around more of the fastener's surface than a standard open-end wrench, dramatically reducing the chance of rounding off the soft metal nuts commonly found on brake and fuel lines.

Q: Is this wrench suitable for professional automotive work?

A: Yes. Made from high-carbon steel alloy with a fully polished mirror finish, this flare nut wrench is durable enough for regular professional use on brake lines, fuel lines, and other tube-fitting fasteners in automotive and mechanical applications.

Q: How should I care for this wrench to maintain its finish?

A: After use, wipe the wrench clean with a dry or lightly oiled cloth to prevent surface residue build-up. Store it in a dry location. The high-carbon steel alloy construction provides inherent resistance to everyday wear and corrosion.
