Accurate Tube Flaring for Trade Repairs

When a tube connection has to seal correctly, the quality of the flare matters. Garrick Herbert flaring tools give mechanics, technicians & workshop teams a controlled way to form tube ends for compatible brake lines, fuel lines & other workshop tubing applications.

The range includes the Garrick Herbert Double Flaring Tool Standard Kit, covering tube sizes from 3/16" to 5/8". With the correct tube preparation & setup, a dedicated flaring tool helps create consistent flare profiles without relying on improvised forming methods.

Good results start before the flare is formed. Tube diameter, material, wall condition, fitting type & specified flare all need to match. For related workshop equipment, explore Automotive & Mechanical, Hand Tools For Auto Repair & Fabrication Tools & Workholding.

What Are Garrick Herbert Flaring Tools?

Flaring tools form the end of compatible tubing so it can mate with the specified fitting or connection. Rather than leaving a tube with a straight cut end, the tool reshapes the end into the required flare profile.

A manual flaring setup typically combines a flaring bar, yoke & forming components. The bar grips the tube while the forming component applies controlled pressure to reshape its end.

With a double flare, the tube end is formed through an additional folding stage before reaching its finished profile. This reinforced configuration is used in suitable automotive & mechanical line applications.

Flaring should never be treated as a one-size-fits-all process. Tube outside diameter, material, wall thickness, fitting seat & flare specification must be compatible with one another.

Why Choose Garrick Herbert Flaring Tools?

A flare that looks close enough isn't necessarily a flare that fits correctly. Controlled tube holding & forming make a substantial difference when reproducing connections during workshop repairs.

Controlled Double Flare Formation

Double flaring requires the tube end to be folded & formed in the correct sequence.

A dedicated double flaring kit provides the clamping bar & forming components needed to carry out this process on compatible tubing, helping the operator maintain alignment throughout the operation.

3/16" to 5/8" Tube Capacity

The Garrick Herbert Double Flaring Tool Standard Kit accommodates 3/16", 1/4", 5/16", 3/8", 1/2" & 5/8" tube sizes, giving workshops a useful spread of capacities within one kit.

Always match the selected opening & forming component to the actual tube size before beginning.

Useful for Brake & Fuel Line Work

Brake & fuel line repairs can involve cutting out damaged tubing, preparing replacement sections & recreating the required end connection.

The correct flaring equipment helps complete that forming stage while maintaining control over the tube.

Built Around Workshop Repair Work

One damaged line can involve cutting, measuring, forming, fastening & inspection before the vehicle or equipment returns to service.

Pair flaring equipment with appropriate Testing & Measurement Tools when diagnosis & checking form part of the repair.

Common Applications

The flare may be small, but it can be a critical part of the finished connection. Garrick Herbert flaring tools suit workshops that regularly prepare compatible tubing during repair, replacement & fabrication work.

Brake Line Repairs

Brake tubing demands careful preparation rather than trial & error.

Before forming a replacement end, identify the required tube size, fitting & flare specification for the vehicle. Cut the tubing square, deburr it correctly & inspect its condition before securing it in the flaring bar.

For equipment used elsewhere in the repair process, see Car Repair & Maintenance.

Fuel Line Repairs

Fuel line work may require a replacement section to be measured, cut, routed & formed to suit the original connection.

Check that the tubing, fitting & flare configuration are specified for the application. Avoid assuming that a flare used elsewhere on the vehicle is automatically correct for the fuel system.

Fleet Workshop Maintenance

Repeated repairs make consistency increasingly valuable.

Fleet & mechanical workshops can encounter several tube diameters across different vehicles & equipment. A multi-size flaring kit keeps several forming capacities together for compatible repair work.

Replacement Tube Fabrication

A new line often needs to follow an existing route through brackets, bends & surrounding components.

Measure the finished route carefully & plan the order of operations before forming the final ends. This is particularly important when fittings must be installed onto the tube before it is flared.

Fabrication & Equipment Repairs

Tube connections aren't limited to vehicle servicing.

Suitable workshop machinery & equipment repairs can also involve formed tube ends. Identify the original connection specification before reproducing it rather than selecting a flare solely by tube diameter.

Product Selection Guide

Start at the connection & work backwards. The fitting specification tells you more about the required flare than the appearance of the old tube alone.

Identify The Required Flare

Determine exactly which flare configuration the system specifies.

A double flare should only be used where the fitting & application require that profile. Different flare standards shouldn't be substituted simply because their dimensions appear similar.

Measure The Tube

Confirm the outside diameter rather than relying on visual estimation.

The Garrick Herbert standard kit covers 3/16" through to 5/8", so select the corresponding position & forming components for the tubing being worked.

Confirm Tube Compatibility

Diameter is only one measurement.

Material & wall characteristics influence whether tubing is suitable for a particular forming operation. Confirm the tubing specification against the application & tool requirements.

Inspect The Mating Fitting

Check the fitting threads, seating surface & general condition.

A correctly formed new flare won't repair an incompatible or damaged mating component.

Plan The Complete Repair

Consider cutting, deburring, bending, measuring, fastening & inspection before starting the flare.

For complementary fastening work around mechanical assemblies, Wrenches provide options for suitable nuts, fittings & workshop connections.

Keep Supporting Tools Within Reach

A flaring kit handles one important stage of the job rather than every stage.

For broader workshop setups, Tool Sets can complement specialist equipment with tools used across surrounding mechanical tasks.

Expert Tips

The easiest flare to correct is the one you inspect before installing it. A few deliberate checks during preparation can prevent an avoidable remake later.

Cut The Tube Square

A clean, square tube end gives the forming components an even starting point.

If the cut is noticeably angled or distorted, correct it before continuing.

Deburr Without Damaging The Wall

Remove burrs produced during cutting while preserving the tube's shape & wall integrity.

Inspect both the internal & external edges before positioning the tube.

Put The Fitting On First

Don't finish a perfect flare only to discover the tube nut is still sitting on the bench.

Where the fitting can't pass over the completed flare, slide it onto the tube first & confirm its orientation.

Set The Tube Projection Correctly

The amount of tube extending above the flaring bar affects the finished result.

Follow the tool's specified setup rather than estimating the projection by eye.

Prevent Tube Slippage

Secure the tube correctly before applying forming pressure.

If the tubing begins moving through the bar, stop. Resetting the work is preferable to continuing with incorrect projection.

Keep The Forming Tool Centred

Check alignment before increasing pressure.

Off-centre forming can produce an uneven result even when the tube was cut & prepared correctly.

Inspect Every Finished Flare

Look for splits, obvious asymmetry, distortion, damaged edges & poor formation.

A questionable flare should be corrected before the line is installed. Additional tightening isn't a substitute for correct tube preparation.
