Waterway Plastics 672-4150 Manifold - 1.5 inch Spigot to 1.5 inch Slip with Four 0.75 inch Barbs
What This Part Is Used For
The Waterway Plastics 672-4150 Manifold is a hybrid plumbing distribution fitting used in spa circulation systems. It accepts a 1.5 inch spigot connection on one side and a 1.5 inch slip connection on the other, while branching flow to four 0.75 inch barb outlets. This configuration allows flexible installation between rigid plumbing and flexible tubing runs. It is commonly used to feed multiple spa jets from a single supply line.
Why This Part Matters
Proper flow distribution is essential for consistent jet performance and system efficiency. A damaged or incorrectly sized manifold can restrict flow or create pressure imbalances. Using the correct OEM manifold ensures reliable connections between rigid and flexible plumbing sections. Incorrect fittings may lead to leaks, vibration, or premature tubing failure.
