What are flaring tools?
Flaring tools are specialised instruments used in plumbing and metalworking to create flared ends on tubes and pipes. The flared end ensures a tight and leak-proof connection when joining pipes or attaching fittings. These tools are indispensable when dealing with copper, brass, aluminium and other metal pipes that require secure connections in various applications.
Parts of a flaring tool
Handle: The part of the tool that provides leverage and control during the flaring process.
Yoke: This component holds the tubing or pipe securely in place while the flare is being formed.
Clamp: The clamp secures the tubing or pipe in the yoke, preventing it from slipping during the flaring process.
Flaring cone: The cone-shaped part that is inserted into the end of the tubing or pipe to form the flare.
Depth gauge: Some flaring tools include a depth gauge to ensure the proper depth for the flare.
Flaring tool uses
- Creating secure connections in plumbing and HVAC systems.
- Forming flares for fuel lines and brake lines in automotive applications.
- Constructing refrigeration systems.
- Crafting precise connections in gas lines and hydraulic systems.
How to use a flaring tool?
Prepare the tube
Cut the tubing or pipe to the desired length using a tubing cutter. Ensure the cut is clean and straight.
Insert the tubing
Slide the end of the tubing or pipe into the yoke of the flaring tool, leaving a small length protruding.
Tighten the clamp
Secure the tubing in place by tightening the clamp over it. The tubing should be held firmly without crushing it.
Lubricate the flaring cone
Apply a thin layer of lubricant to the flaring cone. This prevents friction and ensures a smoother flare formation.
Insert the flaring cone
Insert the lubricated flaring cone into the end of the tubing or pipe. Ensure it’s centred and aligned.
Apply pressure
Firmly hold the handle of the flaring tool and press down on the flaring cone. Apply even pressure to gradually shape the flare.
Inspect the flare
After forming the flare, release the pressure and carefully remove the flaring cone. Inspect the flare for evenness and quality.
How to use a flaring tool for copper tubing and piping?
Flaring tool uses swaging tools for copper tubing and piping. The following are the steps to use flaring tools for the same.
Measure and cut
Measure the required length of copper tubing and use a tubing cutter to make a clean, straight cut.
Smooth the edge
Use a smoothing tool to remove any sharp edges from the cut end of the tubing.
Insert the tubing
Place the cut end of the copper tubing into the yoke of the flaring tool, leaving a small length exposed.
Secure the tubing
Tighten the clamp over the tubing to hold it securely in place without damaging it.
Lubricate and insert
Apply lubricant to the flaring cone and insert it into the end of the tubing, ensuring proper alignment.
Form the flare
Hold the flaring tool’s handle and gently press down on the flaring cone. Apply gradual pressure to shape the flare.
Inspect and test
Release the pressure, remove the flaring cone, and inspect the flare for uniformity and smoothness. Test the flare’s fit with fittings.
FAQs
Can I use flaring tools for plastic tubing?
Flaring tools are generally designed for metal tubing and piping, not plastic.
What type of lubricant should I use?
A light oil or lubricant specifically designed for metalworking is suitable.
Are flared connections more secure than threaded connections?
Flared connections offer greater resistance to leaks, making them preferred in many applications.
Can I use a flaring tool for different pipe diameters?
Flaring tools are adjustable and can be used for various pipe diameters within their specified range.
Do I need to anneal copper tubing before flaring?
Annealing (heating and cooling) copper tubing may make it more malleable, facilitating the flaring process.
Can I use a flaring tool without a yoke?
A yoke provides stability during flaring, so using a tool without a yoke may lead to inaccurate results.
Are flaring tools suitable for DIY enthusiasts?
Yes, with proper guidance and practice, DIY enthusiasts can achieve reliable flared connections using flaring tools.
