Open-Ended Brake Line Wrenches 6-piece GEKO G11148, sizes 8–18 mm

Set of six open-ended brake line wrenches by GEKO covering metric sizes 8–18 mm. These wrenches are designed to grip and turn brake and hydraulic line fittings with a precise fit to reduce the risk of rounding or slipping. The set includes a range of commonly used sizes for automotive brake system maintenance and hydraulic repair work in workshops and garages.

Advantages

The open-ended design provides access to fittings in tight spaces while maintaining full contact on the nut surfaces for improved torque transfer. Each wrench is machined to a slim profile that fits around brake hoses and pipe assemblies, allowing work where conventional combination wrenches cannot. The set offers a complete size range to match various brake line nuts and fittings, reducing the need to improvise with incorrect tools.

Suitable for

• Automotive brake line maintenance and repair
• Hydraulic system servicing in vehicles and machinery
• Workshop and garage general maintenance involving pipe fittings
• Situations requiring a slim-profile wrench for restricted-access fasteners

Key specifications

• Set composition: six open-ended wrenches, metric sizes 8 mm, 9 mm, 10 mm, 11 mm, 13 mm, 14 mm, 15 mm, 17 mm, 18 mm — please verify included sizes in packaging
• Drive type: open-ended wrench profile for line fittings
• Material: hardened steel construction for durability and wear resistance
• Finish: corrosion-resistant surface treatment for workshop use
• Profile: slim head design to access confined spaces around hoses and pipes

How to use

Select the wrench size that closely matches the nut on the brake or hydraulic line fitting. Fit the open end fully onto the nut, ensuring full contact on the flats to avoid rounding. Apply steady torque while maintaining alignment with the fitting; use controlled force and, if necessary, counterhold adjacent fittings or lines to prevent twisting. After use, clean off debris and store the set in a dry place to preserve the finish and mechanical integrity.

Usage recommendations

Use these open-ended brake line wrenches with appropriate safety precautions: wear eye protection, work on cooled components, and avoid excessive impact force. For seized or heavily corroded fittings, apply penetrating lubricant and allow time to penetrate before attempting to loosen. Match wrench size precisely to the nut to reduce damage to fittings and ensure reliable maintenance of brake and hydraulic systems.
