Waterway Plastics 672-4340 Manifold - 1 inch Spigot to Slip with Eight 3/8 inch Barbs

What This Part Is Used For
The Waterway Plastics 672-4340 manifold is used to distribute water or air from a single supply line into multiple smaller hoses. It is commonly installed in spa systems that feed several jets from one main line. The spigot to slip connection allows flexible plumbing configurations. This manifold simplifies complex hose routing.

Why This Part Matters
Balanced flow distribution is critical for consistent jet performance. Improvised fittings often cause uneven pressure and weak jet output. A purpose-built manifold ensures each hose receives a reliable supply. This helps maintain even therapy performance across seating zones.
