What You'll Need

Replacement fittings
Working gloves

Brass flare fittings are compression fittings, used with metal tubing. A flare fitting is located on the end of a copper or brass tube, which provides connection to your plumbing system. But there are times when the brass flare fittings end up having wear and tear, thus it is important that you know how to remove and replace them with new ones. When it comes to removing the brass flare fittings, here are some of the things that you need to prepare in order to remove the brass flare fittings.

Step 1 - Turn off Your Plumbing System

The first thing that you need to do is turn off your plumbing system, otherwise you will end up having more problems than you can handle as soon as you cut away the pipes, such as a stream or jet of water pouring all over the place. Put on a pair of work gloves prior to the next step.

Step 2 - Cut the End of the Tubing Using a Tube Cutter

In order for you to easily remove the brass flare fittings, you need to cut the tubing using a tube cutter. There are different types of tube cutters and since you are using a brass tube, make sure you use a tube cutter meant for this material. This process is important, since it will make it easier for you to remove the flare fitting later on and this does not hinder you while you loosen the flare fitting at the end of the procedure. In any case, do not worry about wasting the tube, since you will need a new tube to fit to your flare fitting if you are going to install a new one.

Step 3 - Slowly Remove the Flare Nut at the End of the Pipe

Using a cloth or rag, remove the flare nut from the end of the pipe. Use a crescent wrench to pry the flare nut open and loosen it up from the pipe tube properly. Wipe the end of the pipe tube with a clean cloth once you are done, and save the pipe tube later if you want to install a new flare fitting into the tube. To facilitate the removal of the flare tubes, make sure that you apply an industrial lubricating oil in order to loosen up the flare nut and other components that you want to remove on your brass fitting.

Step 4 - Wipe Dirt and Grime From the Tube

Once the brass flare fitting has been removed, use a clean cloth and wipe excess grime and dirt the from tube. Keep the entire plumbing system turned off or isolated, until you have installed a new flare fitting to the pipe.

Step 5- Install the New Brass Flare Fittings

To install the new brass flare fittings, all you need to do is to follow the steps that you did earlier in reverse order.
