## Description

For brake-line work that calls for single, double or bubble flares, the SEEKSELF FTOOL-45D-BLACK brings all three 45-degree flare types together in one vise-mounted tool kit.

Its four split-die sizes accommodate tubing from 3/16" to 3/8", including 4.75 mm, so you can select a die for the line you are working with.

The steel tool body, long lever handle and included plastic case make this a practical set for workshop repairs and tubing projects that need a specific flare profile.

## The essentials

This kit forms 45-degree single, double and bubble flares on stainless steel, steel and some soft-metal tubing, including copper. That range makes it useful for common automotive line work, where the required flare can vary by application. The manufacturer also identifies transmission cooler lines and fuel lines as examples of suitable projects.

The four split dies have limiting holes to help keep tubing in position during setup. To operate the tool, clamp its base securely in a reliable bench vise, the tool is designed for vise mounting and is not intended for use under a vehicle. A long lever handle turns to the left to apply force, a layout designed to make operation easier for right-handed users. The kit also includes a graphic instruction manual to guide setup and use.

Compared with a basic flaring tool intended for one flare style, this set offers three flare types and several tubing sizes in one kit. That flexibility is useful when repair work involves different line specifications rather than a single, repeated job.

## Size & fit

Choose from dies for 3/16" (4.75 mm), 1/4" (6.35 mm), 5/16" (8 mm) and 3/8" (9.5 mm) outside-diameter tubing. The listed materials include stainless steel, steel and some soft metals such as copper. Matching the die to the tubing diameter is an important part of setting up each flare.

The package includes the vise-mounted flaring tool body, four split dies, a long lever handle, an instruction manual and a plastic suitcase. The case keeps the tool and dies together between jobs, whether the kit is used for automotive repair or suitable plumbing work.

## Best use cases

This kit suits repair and fabrication tasks where a 45-degree single, double or bubble flare is needed on a compatible metal line. For example, a technician working on a brake line can choose the flare style and die size required for that particular section, then secure the tool in a bench vise for controlled operation. The same flare-making function can also serve work on transmission cooler or fuel lines when the tubing material and size fall within the stated range.

Before turning the handle, secure the tool firmly in the vise and wear goggles and gloves. Keep other people clear while operating, as the manufacturer advises that debris may be ejected during use. This setup makes the kit a workshop tool for bench work, rather than a tool to operate beneath a vehicle.

## What to clarify

**Which flare types can this kit make?** It makes 45-degree single, double and bubble flares, giving you options for different line requirements.

**What tubing sizes do the dies fit?** The four dies are for 3/16" (4.75 mm), 1/4" (6.35 mm), 5/16" (8 mm) and 3/8" (9.5 mm) outside-diameter tubing.

**How should the tool be mounted?** Clamp its base firmly in a reliable bench vise before use. Wear goggles and gloves, and keep others at a safe distance while turning the handle.

## Buying verdict

For automotive repairers and hands-on workshop users who need more than one flare style, the SEEKSELF kit combines three 45-degree flare options with four die sizes and a vise-mounted design. Its useful range across brake, transmission cooler and fuel-line work makes it a practical choice for projects involving compatible steel, stainless steel or copper tubing.
