The 1 in. PVC Spigot or Slip adapters connect the Action Manifold System to your PVC pipe. You can glue 1 in. pipe to the inside or 1-1/4 in. pipe to the outside of the adapter. Action’s 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 your system up and running in no time.
