plumbing adhesiveIf you are doing a plumbing job with copper piping and are uncomfortable using a torch to solder the fittings, you can try a copper adhesive. They come under various brand names, but they all do the same thing; connect copper piping and fittings together.

You will still need to prepare the fittings and the ends of the pipes, by cleaning them with either a brush or emory cloth. This will make the inside of the fittings and the outside ends of the pipes as shiny as a new penny. From there you will need to apply the adhesive.

The copper adhesive will come in a two-chambered syringe that allows you to dispense equal amounts of the product. Each chamber is filled with a different compound and when mixed make the adhesive. Depress the plunger until the product is at the tip of the syringe (you want to get out any air bubbles at the end here). Push out equal amounts of the products on a scrap surface (the product packaging works well here). Mix the two together with a wood stir stick vigorously until well mixed. Use the stick and apply a thin layer of the adhesive to the outside of the pipe and the inside of the fitting. Push the pipe into the fitting with a slight twist and wait until it takes hold.

The package will say how long to wait until you can turn the water back on, but it is usually within 30 minutes. It’s not for all applications, and I would rather solder a fitting, but in some situations it is a good fit.
