ForgeLine™ Pro — Seal Clean Double Flares Without Breaking a Single Line
Secure a Factory-Clean Double Flare — Right the First Time, Every Time
Introducing the ForgeLine™ Pro Brake Flaring Kit: a bench-clamp flaring tool that firmly clamps your 3/16" brake line into a heat-treated alloy block, then drives a two-stage punch straight down for a flawless 45° SAE double flare. No bent bars. No slipping tubing. No trimming extra line due to cracked lips.
Ditch the Bar-Style Tool That Costs You a Foot of Line Every Time
Anyone who's tackled a rear hard line flare on the driveway knows the routine. The cheap flaring bar bends under pressure. The tubing shifts out of the slot. You complete the flare, tighten the fitting, and still see brake fluid bead at the seat. Trim it down, re-bleed, and start over — now three feet shorter than when you began.
➤ Bench-clamp design, zero slip: The alloy block stamped 3/16 SAE 4.75 holds the line firmly with a positioning bolt — no twisting, no bending, no cracked tubing during the second stage.
➤ Dual-stage punch (OP1/OP2): This double-ended punch switches between first stage (mushroom) and second stage (fold-back) without needing to reset the line. Factory-precision double flare, identical lockup, consistent depth.
➤ Hand-tight or bench vise: Attach the rubberized handle for driveway work, or remove it and secure the body in a bench vise to tackle tough stainless steel and copper-nickel lines.
Why Your Last Flare Split — and How the Punch Fixes It
Traditional bar-style tools clamp tubing from the sides to a die. As the bar bends, the tubing shifts slightly, the die presses unevenly, and the flare lip cracks. ForgeLine™ Pro reverses this — the tubing is locked rigidly in the alloy block, while the dual-stage punch presses straight down into the bore. No bending, no slipping, no side load on the tubing wall.
Apply a dab of the supplied pink lubricant to the punch tip before each flare to let the metal flow smoothly instead of tearing. Burr-free lips, tight sealing cones, fitting holds full pressure on the first try. Heat-treated alloy on the block and punch guarantees the geometry stays true long after rust would have wrecked lesser tools.
Why Both Weekend Mechanics and Mobile Pros Keep One Handy
This kit ends up in toolboxes for one main reason: it reliably works on corroded 15-year-old hard lines where other flaring bars slip and bend. One mobile tech said: "Flared a rear hard line on an '08 F-150 in a parking lot last weekend. Three flares, all sealed first try. The bar tool I had before would've cost an hour and four feet of line." — Marcus T.

✓ Seals on the first try: Precise 45° SAE inverted double flares hold full system pressure — no leaks at the bench bleeding or under the vehicle.
✓ Compatible with the crucial metals: Steel, copper-nickel, aluminum, and stainless 3/16" tubing — the exact lines fitting cars and light trucks, including rusted originals.
✓ Perfect for driveway or roadside: The snap-lock case securely stores punch, positioning bolt, and lubricant — no loose parts rattling in your toolbox.
Three Simple Steps: From Cut Tube to Sealed Flare
Step 1: Place your prepared 3/16" line into the alloy block at the correct flare height, then tighten the positioning bolt until the line sits perfectly still.
Step 2: Screw the OP1 (mushroom) end of the double-ended punch into the body, turn the handle down fully, flip the punch, then run OP2 to fold the lip into a finished 45° double flare.
Step 3: Before every flare, apply the included pink lubricant to the punch tip. This ensures burr-free metal flow, tight sealing cones, and a fitting that holds on the first torque.

Common Questions From Users Who Own One
Will this fit 5/16 or 1/4 inch lines?
No — the alloy block is specifically sized for 3/16" (4.75mm), the standard on brake hard lines for almost every passenger car and light truck. Other sizes won’t lock properly or seal well.
Can I use it by hand, or do I need a vise?
Either option works. The rubberized handle provides enough leverage for steel and copper-nickel lines by hand. For stainless steel or tough old corroded lines, remove the handle and clamp the tool body in a bench vise for better control.
Why does the punch have two ends?
That’s the clever part. The OP1 end mushrooms the tubing for the first flare stage. The OP2 end folds the lip back for the second stage. Same tubing, same clamp — just flip the punch. No resetting, no second clamp, no risk of off-center second flare.
How durable is the kit?
The block and punch are heat-treated alloy steel — which is why it costs more than typical bar tools. Wipe it clean after each use, apply a bit of the supplied lubricant to the punch tip, store it in the snap-lock case. It should last longer than the vehicle it's servicing.
Can it repair a flare that’s already leaking?
No — if the existing flare is cracked, misshapen, or leaking, you’ll need to cut it off and start fresh. The tool creates a clean new flare on freshly cut tubing; it doesn’t fix damaged flares.
