Why this one
Open slot for tubing
The open-slot head slides over rigid tubing and wraps around more of the nut than a conventional open-end wrench.
Brake and fuel lines
Suited to brake line fittings and fuel line nuts, grips soft brass and thin-wall fittings, and is also suitable for water pipe connections.
Two sizes per wrench
Each wrench has a different size at each end. Sold individually, from 10 × 11 up to 19 × 22 mm.
Hydraulic work
Also suited to hydraulic systems on vehicles, where the opening lets you work over pipes.
Read the full description
When a brake line fitting or fuel line nut needs to turn, you need a tool that grips the flats without slipping. This Teng Tools double-end wrench is built for exactly that job. The open-slot head slides over rigid tubing and wraps around more of the nut than a conventional open-end wrench, giving you a solid purchase on soft brass and thin-wall fittings.
Sold individually in the 19 × 22 mm combination, this wrench lets you buy precisely the size your repair requires. Replace a missing piece from an old set, add a size your current collection lacks, or simply keep one in the glovebox for roadside work. Weighing 223 g, it travels light and stores easily.
Professional mechanics, fleet technicians, and serious DIY enthusiasts all benefit from having the right tool on hand. Clear size markings let you identify this wrench instantly, even under a dashboard or behind an engine. Pair multiple individual sizes to assemble a custom metric lineup tailored to the vehicles and systems you maintain every day.
Whether you are servicing hydraulic fittings, replacing a hard line, or performing routine maintenance on transmission cooler connections, this Teng Tools wrench delivers the secure grip that keeps nuts intact and knuckles unscathed.
