The 12 Best line Wrench Sets (2023 reviews)

If you often find yourself confused about good set, crescent line wrench set should be your first option for buying. These flare nut wrenches fit well, and are constructed very well. It allows the user to apply more torque, reducing slips that lead to "knuckle busting" as well as allowing for much faster repositioning after each turn. The wrench ends are very thick to resist flexing when breaking a flare nut loose. It's a little slippery to hold so you have to grab it well when it gets wet with brake fluid but this also prevents you from over-torquing and braking bleeder screws. These are inexpensive and well made.

These sizes and lengths of the wrenches are great for smaller spaces and for brake lines as well. They work without rounding out compression fittings. The two-in-one design gives you six common sizes on three tools.

Wrenches fit snug against the nuts
Good investment for long term

Best For Flare nuts: Gearwrench line Wrench Set

Buy on Amazon

Best part: gearwrench line wrench set costs comparatively low and it is available to ship in 24 hours. You can use a regular wrench (or even a crescent wrench) on flare nuts, but these are much more convenient and much less likely to ruin the nuts. The Gear Wrench tool fit and finish is top notch and worked great for the break hose job on the 2001 Tacoma. It is perfect for working on tight spaces or angles. The Flex head design gives the tool a greater versatility when working in areas that are restricted, such as working on brake lines and small hydraulic fittings where many times, a straight wrench simply will not access.

The Flex feature is great for reaching hard to reach fasteners but on occasion makes it difficult to get a firm hold. The swivel heads also make them versatile and able to fit in tight areas. They can be very handy. The heads could be a little tighter but learning how to use a new wrench is part of the game.

Great tool, works better than regular straight flare wrenches
Perfect fit, no slop, high chrome finish
Nice fit and finish and the swiveling head is super handy
Blow-molded tray is a nice addition
