PVC primer is a must have for installations and repairs to PVC and CPVC piping. Our PVC primers are specifically formulated to remove dirt and oil from the surface of piping, as well as softening the piping in preparation for solvent welding. These primers have a purple tint to provide verification that the primer has been applied to the surface of the pipe. We offer a variety of brands, with quantities from 4 oz. to 32 oz., for every job, big or small. So whether you're installing a new sprinkler system, or making repairs to an existing system, purple PVC primer will help you get the job done.
