Achieve a Factory-Perfect Double Flare — Right the First Time, Every Time
Introducing the ForgeLine™ Pro Brake Flaring Kit: a bench-mounted flaring tool that secures your 3/16" brake line inside a heat-treated alloy block, then drives a dual-stage punch straight down to produce a flawless 45° SAE double flare. No bending bars. No slipping tubes. No trimming extra line from cracked lips.
Ditch the Bar-Style Tool That Makes You Waste a Foot of Line Each Time
Anyone who’s flared a rear hard line at home knows the pain. Cheap flaring bars flex under pressure. Tubing slips out of the groove. You finish the flare, tighten the fitting, and still see brake fluid leaking. Cut it off, bleed again, repeat — now you’re three feet shorter than before.
➤ Bench-clamp design, no slip: The alloy 3/16 SAE 4.75 block holds the line firmly with a positioning bolt — no twisting, no flexing, and no tubing fractures during the second stage.
➤ Dual-stage punch (OP1/OP2): Flip the double-ended punch between first stage (mushroom) and second stage (fold-back) without unclamping. Clean, factory-quality double flare with consistent lockup and depth.
➤ Hand-tight or bench-mounted: Use the rubberized handle for driveway jobs, or remove it and fix the body into your bench vise for tough stainless steel and copper-nickel lines.
Why Your Last Flare Cracked — and How This Punch Solves It
Bar-style tools clamp tubing by pressing from both sides, causing the bar to bend and the line to shift slightly, which makes the die contact unevenly and breaks the flare lip. ForgeLine™ Pro reverses this setup — locking the line rigidly in the alloy block while the dual-stage punch drives straight down. No flex, no slip, no sideways pressure on the tube wall.
Apply a smear of the included pink lubricant on the punch’s tip before each flare to let the metal flow smoothly rather than tear. Burr-free lips, tight sealing cones, and fittings that hold full system pressure right away. The heat-treated alloy block and punch keep the tool precise even after beating rusty lines that ruin lesser tools.
Why Both Weekend Mechanics and Mobile Pros Keep This in Their Truck
This kit earns space in toolboxes for one reason: it handles the corroded, 15-year-old hard lines where other flaring bars fail by slipping or bending. One mobile technician said, “Fixed the rear hard line on an ’08 F-150 in a parking lot last weekend. Three flares, three perfect seals on the first try. The bar tool I had before would’ve cost me an hour and four feet of line.” — Marcus T.

The 3 Simple Steps From Cut Tube to Perfect Seal
Step 1: Place your prepared 3/16" line into the alloy block at the correct flare height. Tighten the positioning bolt until the tubing is firmly locked.
Step 2: Screw the OP1 (mushroom) side of the double-ended punch onto the body, turn the handle until it stops, then flip the punch and use OP2 to fold the lip into the final 45° double flare.
Step 3: Before each flare, wipe the punch tip with the included pink lubricant. This ensures burr-free metal flow, a tight sealing cone, and a fitting that holds at first torque.

Real Questions From Those Who’ve Tried It
Will it work on 5/16 or 1/4 inch lines?
No — the alloy block is specifically made for 3/16" (4.75mm), which is the brake hard line size used by nearly all passenger vehicles and light trucks. Other sizes won’t lock properly or seal correctly.
Do I need a vise, or can I use it by hand?
Both options work. The rubberized handle offers enough leverage for steel and copper-nickel tubing by hand. For stubborn stainless or corroded steel lines, remove the handle and secure the body in a bench vise for better control.
Why does the punch have two different ends?
That’s the clever part. The OP1 end shapes the tubing into a mushroom for the first stage. The OP2 end folds the flare back on the second stage. Same tube, same clamping — just flip the punch for perfect alignment. No resetting, no second clamp, no off-center flares.
How durable is the kit?
Made from heat-treated alloy steel, the block and punch last far longer than typical bar tools. Clean and lubricate the punch after each use, store everything in the snap case, and it should outlive the vehicle you’re working on.
Can it repair a leaking flare I’ve already made?
No — if your existing flare is cracked, deformed, or leaking, cut it off and start fresh. This tool creates a new clean flare on freshly cut tubing; it doesn’t fix damaged ones.
