Properly Connecting PVC Pipes to Brass Pipes

Piping or Tubing

It doesn’t always look great to the naked eye, but sometimes (especially in plumbing applications) it is necessary to connect a PVC pipe to a brass pipe. Some basic plumbing knowledge and a specific list of tools are all you need to make it happen, so don’t panic if you’re not an expert-level plumber or handyman!

First off, you should realize that PVC and brass are very different from each other. PVC is fairly inexpensive and is a product made of lightweight vinyl. Brass on the other hand, is a material made of dark, rich metal. The reason why connecting these two pipes in the first place is so unorthodox is because brass pipes are usually in plain sight while PVC is hidden, behind the scenes. But they can be connected if the situation calls for it.

The tools you need to properly connect the quality PVC or brass pipes from Detroit Nipple Works using pipe couplings includes:

  • A metal-bladed hacksaw
  • Phillip’s head screwdriver
  • Plumber’s silicon grease
  • Tape Measure

A rubber coupling is best when actually attaching the pipes but there are certain specifications that call for certain corresponding couplings; if the pipes are of the same diameter, a standard coupling is necessary. If one pipe is smaller than the other, use a reducer coupling.

Once you’ve measured the diameters of your PVC or brass pipes, thus allowing you to decide on the size of your coupling, use your saw to cut both ends of the pipes off and make sure they are smooth and evenly-cut. Then apply a thin layer of plumber’s silicon grease around the end of each pipe. The coat should be about an inch wide.

Next you’ll want to slide your pipe coupling over one end of the brass pipe, to the point where it makes it halfway through, then you can slide the PVC pipe into the opposite coupling end. Use your screwdriver to then tighten the clamp on both sides of the coupling and make sure the connection is sturdy, leaving no possibility for future leakage.

If you decide to go the route of threaded joints, you’ll want to attach a PVC male threaded fitting to a threaded brass fitting or else you may notice dripping once your connection is put to use.
