Our PVC Poly Adapters connect Action's Heavy-Duty Manifolds to ¾", 1" or 1¼" Poly pipe. Our heavy duty manifold systems are constructed out of thick schedule 80 PVC, o-ring sealed for tool-less installation and fully unionized. Never cut your system apart again to change a junk valve. With our wide range of manifolds and adapters, you'll have you system up and running in no time.
