How to Flare Copper Tubing Properly for Plumbing

How to Flare Copper Tubing?

To flare copper tubing, it is important to have the right tools and techniques in order to create leak-proof connections.

It is recommended to invest in a flaring kit or hire a knowledgeable plumber to ensure proper flaring.

The first step is to cut the copper tubing using a tube cutting tool.

After cutting, any loose pieces of copper should be cleaned off.

The actual flaring is done using a reamer placed on top of a flare form, with the conical point against the tubing.

Over-tightening can cause the copper to split, so caution should be taken.

Repairing a smooth flare can be done by making a new cut under the flared part and repeating the process.

Flaring smaller sized copper tubing for household use is relatively simple, while flaring copper water tubing for water service lines requires more skill.

It is important to use the proper type of copper tubing, such as Type K, which is ideal for flaring due to its thick wall.

Brass flare fittings must be used for flared copper tubing, as they provide durability, versatility, and resistance to corrosion.

Overall, the process of flaring copper tubing requires precision and attention to detail to ensure leak-proof connections.

Flaring copper tubing may initially seem challenging, but with the right tools and techniques, it can be a relatively simple process. Follow these step-by-step instructions to effectively flare copper tubing:

  1. Cutting the Tubing: Begin by using a tube cutting tool to cut the copper tubing accurately for a clean and precise cut.

  2. Removing Excess Copper: After cutting the tubing, ensure that there are no loose pieces of copper at the end of the tubing.

  3. Preparing the Flare Form: Place the reamer on top of the flare form, aligning the conical point of the reamer against the tubing.

  4. Flaring the Copper: Slowly and steadily tighten the reamer, allowing the conical point to gently flare the copper. Be cautious not to over-tighten, as this can cause the copper to split.

  5. Inspecting the Flare: Check the flare to ensure that it forms a 45-degree angle uniformly around the tubing and adequately covers the face of the flare fitting.

  6. Addressing Imperfections: If the flare is uneven or poorly formed, you can create a new cut beneath the flared part and repeat the entire process.

Remember, by diligently following these steps and utilizing the appropriate tools, you can successfully create accurately flared copper tubing connections.

  • Ensure that you have a tube cutting tool for a clean cut.
  • Pay attention to the angle of the flare, which should be 45 degrees.
  • Avoid over-tightening the reamer to prevent splitting the copper tubing.

Choosing The Right Type Of Copper Tubing And Fittings For Flaring

When it comes to flaring copper tubing, it is crucial to choose the right type of tubing and fittings for the job. Type K copper water tubing is ideal for flaring because it has a thick wall that can withstand the enlargement caused by flaring. On the other hand, Type L and M copper are meant to be soldered or brazed, not flared.

Furthermore, it is important to use brass flare fittings with copper tubing. Brass fittings are known for their durability, versatility, malleability, and resistance to corrosion. They also act as a good conductor, ensuring better efficiency when used for hot water distribution.

For water service lines with a diameter of up to 2 inches, K copper is preferred as it is relatively easy to bend or shape. However, working with 2-inch K copper may require the expertise of a professional plumber.

In conclusion, flaring copper tubing is a useful skill to have for various applications. By using the proper tools and techniques, such as flaring kits, you can ensure leak-proof connections. Avoiding improvised tools and investing in a flaring kit or hiring a knowledgeable plumber are highly recommended. Following step-by-step instructions and choosing the right type of copper tubing and fittings will further contribute to successful and durable flaring connections.

– Ideal for flaring: Type K copper tubing (has a thick wall)

Frequently Asked Questions

What technique must be used to make a good flare on copper tubing?

To make a good flare on copper tubing, it is essential to utilize the proper technique. Begin by positioning the reamer on top of the flare form, ensuring that the conical point is in contact with the tubing. Gradually tighten the reamer, allowing the conical point to gently flare the copper tubing. It is crucial to maintain a steady tightening motion, as the process becomes progressively more challenging. Continue tightening until the handle can no longer be moved, but it is vital to avoid over-tightening, as this may hinder the desired outcome.

Can you flare copper pipe?

Yes, copper pipes can indeed be flared. Flaring is a technique used to connect copper tubes to various fittings or to connect tubes together. Flared ends typically have a conical shape, allowing for a secure and leak-free connection. The bar-type flaring tool is commonly used for copper tubing as it comes with multiple bits that can accommodate different sizes of pipes or tubes. With this tool, you can easily achieve precise and reliable flares for your copper pipes.

What is the correct angle for flaring?

When it comes to determining the correct angle for flaring, it depends on the specific flaring fitting standard being used. The three most common standards include the 45° SAE flare, the 37° JIC flare, and the 37° AN flare. Each standard has its unique angle designed to ensure proper sealing and connection. Therefore, it is crucial to follow the appropriate standard’s recommended flare angle for optimal fitting performance and compatibility with the respective system.

What is the process of flaring?

Flaring is a process that involves the controlled combustion of natural gas when it cannot be economically or logistically utilized. This practice has been used for over a century in the oil industry to dispose of excess gas produced during oil extraction. However, flaring persists today due to a combination of factors, including market constraints and a lack of regulatory oversight, as well as insufficient political determination to address this issue.

When oil is extracted from the ground, it often comes with associated natural gas, which can be challenging to capture and transport. Flaring, therefore, serves as a method to safely dispose of this gas by burning it off. While efforts have been made to reduce flaring and promote alternative means of utilizing the gas, such as capturing it for energy generation or selling it, numerous obstacles remain. These include economic considerations, inadequate regulation, and a lack of strong political commitment to address the environmental and economic consequences of flaring. Consequently, despite its long history and known environmental impact, the process of flaring continues to persist.
