Here at Able Skills we are now providing basic tutorial videos for our students and generally for people interested in learning new skills. In this tutorial our expert Plumbing instructor Jim goes over how to correctly join pipework together using compression joints. Compression fittings are used to join copper piping together for water and gas systems that provide a watertight seal between two pipes or a pipe.
The first step in this is making sure each ends of your pipework are round. It is important to inspect your tools and materials.
The second step in preparation. You will want to slide on the nut first followed by an olive as shown in the picture below.
Next, you will need to apply a sealing to the end of the pipe past the olive. You could use Plumbers blue, plumbers green and other products. Make sure that the product is WRAS approved as this is for Hot & Cold water surfaces. In this example, we are using PTFE. To do this wrap two turns around the pipe past where the olive is placed.
