The Insider Directional Flow Outlet is designed to fit directly inside 1.5" Schedule 40 pipe, providing a clean, low-profile solution for directing water flow. Featuring a self-aligning design, the outlet installs easily and positions itself correctly for a secure fit without complicated adjustments. The 3/4" eye opening creates a focused return stream that helps improve circulation, enhance water movement, and promote more even distribution of chemicals and water throughout the vessel.
