The Waterway 413-4520 barb adapter is designed for compatible plumbing applications using a 2 inch spigot connection and a 3/4 inch ribbed barb outlet. This type of fitting is useful where a larger rigid plumbing line needs to transition directly to a smaller flexible hose or tubing branch.

In spa and water-system plumbing, that kind of reduction and connection-style change can often be handled more cleanly with a purpose-built adapter rather than stacking several separate fittings. This Waterway component helps support that more organized approach.

For compatible plumbing repairs and installations, this Waterway barb adapter is a practical solution when a 2 inch spigot-to-3/4 inch ribbed barb transition is required.

  • Waterway barb adapter
  • 2 inch spigot x 3/4 inch ribbed barb connection
  • Helps transition from larger rigid plumbing to flexible tubing
  • Useful for compact and efficient plumbing conversions
  • Supports cleaner line adaptation in spa and water systems
