Compression fittings are a type of plumbing fitting that is commonly used to connect pipes together. These fittings are very popular because they are super easy to use and install. They do not require any special tools, and can be easily demounted and removed if needed. Typically they are made from Brass, which is a recyclable material, adding sustainability to its many accolades. Compression fittings are used across a range of applications, in residential and commercial plumbing systems, including water supply lines, gas lines, and air lines.
You might be wondering about how to fit compression fittings, In this article, we will discuss the steps involved in fitting compression fittings, along with some tips and tricks to make the process easier and more efficient.
Step 1: Gather Your Tools and Materials
Before we begin with how to fit compression fittings, you will need to gather the necessary tools and materials. Here's a list of what you'll need:
- Compression fittings (make sure you have the correct size and type for your application)
- Pipe (made to BS EN 1057)
- Pipe cutters
- Adjustable wrenches or pliers
- Deburring tool
Step 2: Cut the Pipe to the Correct Length
The first step in fitting compression fittings is to cut the pipe to the correct length. Use a pipe cutter to make a clean, square cut on the end of the pipe that will be inserted into the fitting. It is important to make sure that the pipe is cut to the correct length so that it will fit snugly into the fitting.
You need to make sure the pipe hits the pipe fitting back-stop, so that the olive can correctly grip the pipe. Secondly, don't make the pipe too long, otherwise you may introduce strain into the wider pipe system.
Step 3: Clean and Deburr the End of the Pipe
After cutting the pipe, it is really important to deburr the end of the pipe. This can be done with a deburring tool, which will remove any rough edges or burrs on the end of the pipe. Deburring the end of the pipe will remove any residue or dirt to help ensure a tight seal when the compression fitting is installed.
Step 4: Slide the Compression Nut and Ferrule onto the Pipe
Next, slide the compression nut and olive onto the end of the pipe, like you can see in the photo above. The compression nut is the part of the fitting that will be tightened to create a seal, while the olive is a small ring that fits inside the compression nut, simultaneously gripping the pipe and creating a watertight seal around the pipe.
Step 5: Insert the Pipe into the Compression Fitting
Insert the end of the pipe into the compression fitting. Make sure that the pipe is pushed all the way into the fitting until it reaches the bottom.
Step 6: Tighten the Compression Nut
Use an adjustable wrench or pliers to tighten the compression nut onto the fitting. Tighten the nut until it is snug, but do not over-tighten it. Over-tightening the nut can damage the fitting and cause leaks.
Step 7: Test your System and Check for Leaks
Once the compression fitting is installed, it is important to check for leaks. Turn on the water supply or gas supply and check all fittings for any signs of leakage. If you notice any leaks, tighten the compression nut a little more and check again.
