Brake Line Wrench, 12x14 mm, Double-Ended Flare Nut Design

Brief Overview

This is a specialized brake system service tool designed for technicians who need reliable, damage-free access to brake line fittings. The double-ended design provides two common sizes—12 mm and 14 mm—in a single tool, eliminating fumbling through multiple wrenches during hydraulic brake work. The box-style jaw profile grips the hex shoulders of flare nuts firmly while minimizing the risk of rounding, a critical advantage when working with soft brass fittings on modern vehicles. Stock this alongside smaller brake line wrenches and larger flare nut options to offer your customers complete brake system coverage.

Key Features

• Double-ended design: 12 mm and 14 mm sizes on one tool
• Box-style jaw profile: Engages four corners of the hex nut for superior grip and reduced cam-out
• Slim, tapered handle: Minimal material for tight engine bay access while maintaining strength
• Chrome-plated steel construction: Corrosion-resistant finish withstands aggressive brake fluid exposure
• Offset jaw geometry: Prevents knuckle contact on confined brake line routing
• Stamped size markings: Clear identification without time-consuming trial fitting

Business Advantages for Resellers

Brake line wrenches are non-negotiable consumables in any professional garage—technicians cannot safely service hydraulic systems without them. This 12x14 mm size is a high-turnover item for mid-range vehicle brake work. The box-jaw design commands a price premium over standard open-end wrenches because it eliminates costly fitting replacements when rounded nuts occur. Position this as part of a complete brake service kit or as an individual replacement for shops that wear out their existing tools. Low acquisition cost + high demand = strong margin opportunity.

Why This Matters

Technicians who use open-end wrenches on brake fittings create rounded nuts that require complete line replacement—a costly error that damages shop reputation and customer trust. This tool prevents that problem. The box-jaw design is the professional standard in brake service for a reason: it works. Order in bulk for your retail stock or distribute to your network of service partners. Brake systems are worked on year-round, making this a reliable revenue generator.
