Flaring Tool Kit in Nairobi | Wisdo Merchants

Flaring Tool Kit for Leak-Free Copper Pipe Joints

Most refrigerant leaks on split air conditioners start at the flare joints. A cracked, off-centre or rough flare will seep gas slowly until the unit stops cooling, and the client calls you back. A good flaring tool kit prevents this by making clean, even flares every time. At Wisdo Merchants, we supply flaring kits to AC installers, refrigeration technicians and plumbers across Nairobi and Kenya.

A flaring tool spreads the end of a soft copper pipe into a cone shape. This cone then seals against a matching fitting when the flare nut is tightened, giving a metal-to-metal seal with no brazing. As a result, it is the standard way to connect the copper pipes of a split AC to the indoor and outdoor units.

Features and Benefits of the Flaring Tool Kit

• Clean, even flares. The cone and clamp form smooth, centred flares that seal properly against the fitting.
• Several pipe sizes in one tool. The flaring bar holds the common copper pipe sizes used in AC and refrigeration work.
• No brazing needed. Flare joints connect units without a torch, which saves time and avoids fire risk indoors.
• Easy to use. Simply clamp the pipe, turn the handle and the cone forms the flare.
• Portable. The kit packs into a carry case for site work.

For installers, this means fewer leaks and fewer callbacks. Meanwhile, clients get AC units that hold their gas for years.

Applications of the Flaring Tool Kit and How to Use It

• Installing split air conditioners, connecting pipes to indoor and outdoor units
• Replacing damaged flare joints on leaking AC lines
• Fridge and cold room repairs where flare fittings are used
• Fitting service valves and connectors on copper pipes
• Gas and water lines that use flare fittings

Making a Perfect Flare

Picture an installer connecting a new split unit’s pipes to the outdoor unit. First, they cut the copper pipe square with a tube cutter, never a hacksaw, and remove the burrs from inside and outside the pipe. Next, they slide the flare nut onto the pipe before flaring. After that, they clamp the pipe in the flaring bar at the correct height and turn the yoke handle until the cone forms a smooth, even flare. Finally, they check the flare for cracks, then tighten the nut onto the fitting with a torque wrench.

Once all joints are made, pressure-test with nitrogen and pull a vacuum using our professional dual gauge set. Then charge the system, for example with our HFC-410A for split units.

Tips for Leak-Free Flares

Always deburr the pipe, because burrs scratch the sealing face and cause leaks. In addition, a drop of refrigeration oil on the flare face helps the joint seal smoothly. For joints that must be brazed instead, use our screw-on brazing torch.

Safety and Handling

• Wear safety glasses. Copper burrs and filings can fly off when cutting and deburring.
• Use the right pipe. Flare only soft, annealed copper; hard copper can crack.
• Don’t over-tighten. Excessive torque on the flare nut can split the flare.
• Keep the cone clean. Wipe the cone and flaring bar after use so dirt doesn’t mark the next flare.
• Store in the case. This protects the cone and keeps all parts together.

Frequently Asked Questions

What size pipes can I flare?

The flaring bar holds the common copper pipe sizes used in AC and refrigeration. Check the sizes stamped on the bar, or ask our team before buying.

Why do I need to put the nut on first?

Once the pipe is flared, the nut can no longer slide on. Always fit the flare nut before flaring.

Why is my flare cracking?

Cracks usually come from hard copper, over-flaring or a dry cone. Use soft copper, set the pipe at the correct height and add a drop of oil.

Can I reuse an old flare?

It’s better to cut off the old flare and make a new one. Reused flares often leak.
