What This Part Is Used For
The Waterway Plastics 672-4030 Barb Manifold is a multi-port distribution fitting used in spa and pool plumbing. It splits a single 1 inch feed into four 3/8 inch branch lines. This allows water or air to be evenly distributed to multiple jets or outlets. It is commonly found in spa jet plumbing layouts.

Why This Part Matters
Balanced flow is essential for consistent jet performance. A damaged or restricted manifold can cause weak or uneven output. Using the correct OEM manifold maintains proper distribution across all connected lines. Incorrect fittings can compromise system performance and longevity.
