The Waterway 413-4370 barb adapter is designed for compatible plumbing applications using a 3/4 inch barb connection and a 1-1/2 inch spigot outlet. This type of adapter is useful where flexible tubing must transition into a larger rigid fitting path without relying on several separate components to make the change.

In spa, water feature, and support-line plumbing, having the correct Waterway adapter can help keep the installation more compact and easier to service. Even where a similar configuration exists in another part number, matching the exact component to the system remains important.

For compatible plumbing service and installation work, this Waterway adapter is a practical choice when a 3/4 inch barb-to-1-1/2 inch spigot transition is needed.
