Plumbing manifolds to distribute water and air to hot tub jets and air injectors.
Manifold port sizes are nominal PVC measurements that relate to the Inner Diameter of the Connecting Hose or Pipe.
About PVC Measurements
Example: A 2 inch slip port on a manifold accommodates a 2 inch inner diameter PVC flex hose or pipe. It also accommodates the 2" spigot connection of another PVC part. Hose and Spigot connections fit into Slip connections. Plumbing size is given by the hose inner diameter/plumbing size - not any part on the actual manifold or PVC part.
Got a 2 inch hose? You have 2 inch plumbing for that line. Got a 3/4 inch inner diameter hose? That is would need a 3/4" port on a manifold.
We also offer caps and plugs to seal off any unneeded manifold ports.
