Description

The GearWrench 89100 5 Pc. Ratcheting Flex Head Flare Nut Wrench Set, SAE is the brake-line and fuel-line specialist set for loosening and tightening hex flare nuts without rounding them. On sale now for $73.33, down from a $166.65 compare-at price — a 56% discount you can buy online today.

Product Specifications

Sizes in the Set

5 double-size SAE wrenches — two sizes on each wrench, saving toolbox space
Covers the common SAE flare nut size range for fuel, brake, and hydraulic lines

Materials & Build

Durable alloy steel construction
Bright full polish chrome finish for corrosion resistance and easy cleanup
Ratcheting flex head bodies for angled access in tight engine bays

Functions & Compatibility

Hex-shaped heads wrap more of the soft flare nut than an open-end wrench, preventing rounding on brass and soft-steel fittings. The ratcheting action lets you work flare nuts in confined spaces without lifting the wrench, and the flex head reaches angled fuel and brake line fittings.

Best Use Cases

Brake line and hydraulic line flare nuts
Fuel line fittings and soft-metal hex nuts
A/C, transmission cooler, and general line service

Comparisons & Alternatives

Vs. standard flare nut wrenches, the 89100's ratcheting flex heads cut work time dramatically in tight bays. Vs. open-end wrenches, the full hex wrap eliminates rounding on soft fittings. At $73.33 versus a $166.65 value, it's a deal-price alternative to buying individual wrenches.

Frequently Asked Questions

What sizes are in the GearWrench 89100 set?

The 89100 includes 5 SAE wrenches, each double-sized to cover two flare nut sizes per wrench — the complete common SAE range for fuel, brake, and hydraulic line fittings.

Is the 89100 good for brake lines?

Yes — the hex-shaped heads grip soft steel and brass flare nuts fully, and the ratcheting flex head reaches fittings in tight engine bay and chassis locations without rounding them.

What is the current price and are there discounts?

The sale price is $73.33, down from a $166.65 compare-at price — 56% off. Coupon SAVE15 takes an extra 15% off, and the order qualifies for free shipping over $45.00.

How does this compare to standard flare nut wrenches?

Standard flare nut wrenches must be lifted and repositioned for every swing; the 89100's ratcheting flex heads keep engaging the nut in confined spaces, saving significant time.

Where can I buy the GearWrench 89100 online?

Right here at Driven Fastener Works — order online today to lock in the deal price, coupon savings, and free shipping.

Perfect for brake line work

Did a full brake line job on my F-150 with these and didn't round a single fitting. The flex head gets you the right angle in tight spots along the frame rail, and the ratcheting action saves a ton of time when you're working with short flare nut movements. Wish I'd bought this set years ago.

Great set, no case

The wrenches themselves are excellent. Smooth ratcheting, good flex head tension, and the flare nut design really does grip those soft fittings without slipping. Only knock is it ships in a plastic tray instead of a proper roll or case. Works great though, at this sale price it's a no-brainer.

Grip without the slip

These grip brake fittings better than any open-end I've used. Six points of contact and the ratchet means fewer broken knuckles on rusty fuel lines.

Decent but heavier than expected

Build quality is fine and the flex head works as advertised, but they're heavier in the hand than my old flare nut wrenches. Ratcheting mechanism occasionally feels gritty under load. Gets the job done.
