The Waterway 672-4370 8-port manifold is designed for compatible plumbing applications using a 1 inch slip connection, dual 1 inch spigot connections, eight 3/8 inch barb outlets, and four included plugs. This style is especially useful in systems that need a high number of flexible branch outlets along with added configuration flexibility for ports that may not all be used at once.

The included plugs make it possible to customize how many outlets are active during installation or future service changes. With its multiple main-body connection options and eight branch outlets, this Waterway manifold is a practical choice for more complex spa and hydrotherapy plumbing layouts.
