How to Attach White PVC to Black PVC How to Attach White PVC to Black PVC
Black ABS plastic pipe is often referred to as black PVC. It's similar in property to PVC, but is slightly different. The black ABS is flexible, and can be used in applications where flexibility is a must. It can be connected to PVC to form a water-tight seal. Connecting this type of pipe with standard white PVC is easy and straightforward. Here's what you need to know.
Step 1 - Loosen Clamps
You will need to make sure that the stainless steel clamps that are on your rubber coupling are loosened. You do not need to remove them, but just loosen them enough where you will be able to work on them. The best way for you to loosen them is to use your hex-head adapter. A drill will also be necessary while you are doing this.
Step 2 - Clean the Tubing
It is a good idea to make sure that you have the black ABS as well as the PVC cleaned on both ends. If there is any dirt or dust that is left on the ends, then the actual connection process can be interfered with. It is simple to clean the tubing. You will simply need to wipe it down using a damp cloth. Make sure that the cloth is not wet but slightly damp.
Step 3 - Rubber Coupling
You will need to get one end of your rubber coupling and then slide it over the end of your black piping. Once you have done this, you will then need to get the other end of your coupling and slide it over your white PVC pipe.
Step 4 - Tighten
You are now ready to get the stainless steel clamps tightened. In order to properly tighten them, you will need to get your tee-handled torque wrench out. It is important that you make sure the clamp sits in the molded groove portion of the rubber coupling before you start to tighten. This is done so that you will be able to make sure that there is a tight fit without risking damage to either the PVC or ABS pipes.
Step 5 - Testing the Connection
You will find that more often than not, the pipe combination that you are working on will most likely be used for a type of plumbing or a water application. Because of this, it is important that you take the time to test the connection for leaks before you attempt to install anything or begin work on it at all. If you begin to run water through your pipe and see any leaks at all, then you will need to check to make sure that you used the right torque for your clamps. You will need to fix this issue as soon as possible and do not stop until the leaks have ceased.
